Highlands County School District

Highlands County School District was dealing with severe network congestion, with Chromebook updates taking up to a week to download—causing headaches for the IT team and disrupting classrooms. Technology Manager Harry Howes, with 25 years at the district, knew that upgrading links across all 18 schools wouldn't make a difference, and would be costly, complex, and time-consuming.

Somerton School District 11

Somerton School District 11 initially set out to replace outdated Apple caching servers at three of its seven schools, aiming to improve its network's capacity to support its 1:1 Apple Air initiative.

However, it soon became clear that bandwidth alone wasn't the issue. Despite having the necessary capacity, the district's existing network hardware — particularly the firewall — couldn't handle high throughput during peak times. As a result, up to 50% of their bandwidth was routinely blocked, causing severe congestion and impacting classroom activities.

Matanuska-Susitna Borough School District

Matanuska-Susitna Borough School District, the second largest district in Alaska, faced a significant challenge when its Qwilt cache server reached end of life.

For years, the district had relied on caching to ensure that staff and students could access digital resources quickly and reliably. Now, without a cache server, every single content request or update would now be served directly from the Internet, rather than the local network, overwhelming the district's internet connection.

Jefferson County School District

At Jefferson County School District, the second largest school district in Alabama, Chromebook updates were maxing out the district's bandwidth.

To alleviate the strain, the district implemented CACHEBOX.

West Clermont Local School District

Over the course of 6 years West Clermont Local School District had to increase its Internet connection 4 times to accommodate growing demand. Tech Director Larry Parece recognized that this was quickly becoming a never-ending upgrade cycle – and that more bandwidth was not the solution.

This time, instead of opting for another costly and time-consuming bandwidth upgrade – along with the additional kit needed to support it – Larry considered caching.

Fabens Independent School District

At Fabens Independent School District, students and staff should be experiencing superfast internet access, with 4 times the FCC's recommended bandwidth per student. However, despite this, they still faced slowdowns during peak usage periods.

Closer inspection confirmed that congestion was not causing the slow speeds. Even if it had been, increasing capacity wasn't a feasible or financially sustainable option. Tech Director Michael Perez realized that a caching solution was the answer.

Whiteriver Unified School District 20

Whiteriver Unified School District 20 was struggling frequently with Chromebook system updates consuming its entire connection, grinding the network to a halt, and putting classroom learning at risk. With internet costs already exceeding $650,000 annually, upgrading the connection wasn't a cost-effective option.

Tech Director Pierre Dehombreux sought a less costly way to reduce the strain of software updates. His ideal solution needed to be easy to set up and maintain.

Finkelstein Memorial Library

Finkelstein Memorial Library first deployed an E-Rate-funded CACHEBOX in 2016 as part of a broader network overhaul.

Since then, the appliance has become a core part of the library's network to maintain fast performance for users across a wide range of user access computers, loaned Chromebooks, and devices accessing the free public Wi-Fi.

Caching underpins edtech investments at nations' 4th largest school district

Classroom content accelerated: 230Kbps from web, 4.5Mbps from cache

Chicago Public Schools (CPS) has been using caches for over a decade to accelerate access to resources in the classroom and make their network radically more efficient. And even with upgraded networks, that's just as relevant today as it's always been.

HTTPS express: Schoology speeds surge with CACHEBOX

Schoology content at Bellefontaine City Schools was slow. Despite a 500Mbps connection, content was often arriving to students at less than 1Mbps.

District Technology Coordinator Marc Stakey recognized that upgrading to a higher-cost, higher-capacity core connection wouldn't solve the problem.

Wildcats fight off bandwidth blues

Osage County R-2 Schools, a school district in Missouri, had first introduced a partial BYOD (Bring Your Own Device) scheme in 2017. With 400 users connecting to its 30Mbps internet at peak times, the district consistently found its bandwidth maxed out by software updates.

Caching a piece of Kake

Twenty thousand dollars. That is what Kake City School District in Alaska pays for its 200Mbps internet connection per month.

Bandwidth in Alaska is notoriously expensive with schools paying big bucks for small connections. Another recurring issue is the distance between districts and their service providers. Kake City's service provider is located on another island, which adds to the latency the district experienced.

CACHEBOX turns up the heat

Perry County School District in Alabama needed a solution to maximise its limited bandwidth. With 2,000 devices on a 1Gbps link the district's connection was struggling to keep up with growing internet traffic. Content was slowing down due to congestion, and the district wanted to protect access to its rich online curriculum content.

Bayless pay less

Bayless School District, home of the Bronchos, in Missouri first deployed a CACHEBOX in 2017. Tired of having to manually perform their Chromebook and Windows updates, Tech Director Fadil Hamidovic was in desperate need of a different solution.

CACHEBOX provided Fadil with the solution to his problems with updates, and also resolved his underlying issues with speed and costly bandwidth. At the time, Bayless's 100Mbps connection was not sufficient to fully support its students, resulting in dramatic slowdowns in the classrooms and disengaged students.

Libertyville frees up core caching content

Libertyville Elementary School District 70 is a 1:1 device district, implementing an array of iPads and Chromebooks for students to use.

However, the district would routinely find its network congested and, even during quieter school hours, teachers would still complain about learning content like videos being slow to load.

CACHEBOX charms Kalispell

With plans to expand its 1:1 device scheme across its 11 schools, Kalispell School District 5 soon found its network regularly congested. With thousands of users accessing bandwidth-heavy content at the same time, the network would become saturated bringing things to a grinding halt.

Lewis County finds gateway to YouTube content

Lewis County C-1 School District is a 1 device per student (1:1) district in Missouri with almost 1,000 students. The district relies heavily on Google Classroom and YouTube content for teaching. However, students were easily distracted by other content on YouTube and, due to a failing YouTube filter, teachers had no way to control the content that students were exposed to.

Martins Ferry steams ahead with caching

Martins Ferry City School District's online curricula mainly consists of Google Classroom content and, as such, it has fully adopted a 1:1 Chromebook scheme. But, with a 500Mbps connection and 1,500 students often in need of simultaneous internet access, the district's broadband connection could not handle peak-time demand.

CACHEBOX? More like CASH box

Waldron Public School District 45 in Arkansas caters for 1,400 students across four schools. Its 1:1 initiative has seen students equipped with Windows, Chromebook and Apple devices. But, with its 450Mbps bandwidth capacity under pressure from hundreds of students connected at the same time, congestion soon became a problem, causing slow web access in class.

CACHEBOX flattens peaks

After introducing a 1:1 program with 350 Chromebook computers, Schlarman Academy would often find its 200Mbps internet connection congested. The resulting slowdown was causing disruption in the classroom.

Caching and bandwidth in unity at Community

Community R-VI School District in Missouri first purchased a CACHEBOX in 2017. Back then the district had first implemented a 1:1 program for its 350 students and needed a solution to optimise its small bandwidth of only 50Mbps.

CACHEBOX is big in the Empire State

Manhattan Christian Academy in New York benefits from a large 1Gbps internet connection to support its less than 300 students and with a state-of-the-art computer lab set up, student learning should be at an all-time high.

Caching is sweet at Mount Carmel

With whole classes accessing the same online content at the same time, Our Lady of Mount Carmel's 100Mbps link was regularly congested. Requests quickly backed up, leaving students and teachers with such a slow user experience that student engagement was put at risk.

Alaska: The Fast Frontier

Yakutat, like a lot of remote Alaskan school districts, pays eye-watering sums for below-average internet capacity. Despite paying out $30,000 a month, classroom demand would quickly overwhelm its 25Mbps connection, making online testing, learning and independent research almost impossible for its students.

Caching updates is the Maine event

Despite an impressive 6.4Mbps per-student capacity, Maine School Admin District 49's (MSAD) network would still grind to a halt. At peak times classroom demand would overwhelm its internet link, causing a dramatic slowdown as requests queued and students were forced to wait for content to download.

Amsterdam nether knew faster web

In order to sufficiently support it's 143 students, by FCC standards, Amsterdam Elementary District 75 needs more than triple its current bandwidth. With a vision to provide students with a quality learning experience, Amsterdam needed a solution that would accelerate its current bandwidth, without an actual bandwidth increase.

Dedicated caching for a dedicated community

As the fourth largest school district in Thurston County, Washington, Yelm Community School District handles traffic for up to 7,500 users daily, all accessing the internet using a variety of devices – from Apple Macbooks and iPads to Chromebooks and laptops.

Believers Academy's faith in caching rewarded

Believers Academy is a charter school in Florida, dedicated to providing free education to students aged fourteen to twenty one. The school provides a safe place for them to learn valuable reading and math skills as well as building on their vocabular abilities.

Discovery fights off latency

With a 1:1 scheme consisting of 1,000s of Apple devices, Discovery High School quickly found out how great an issue software updates are going to be for its network. With student learning at risk, Discovery needed a way to clear out its updates faster.

Having initially looked at getting an Apple caching server, Discovery chose CACHEBOX after seeing exactly how much it could benefit from caching everything rather than just Apple traffic. Not only does CACHEBOX serve 98% of content from Apple.com, but between 50 and 60% of content from educational sites like biology4kids.com is served locally by cache.

CACHEBOX fires up Mandan's 'IGNITE' project

Mandan School District in North Dakota has started implementing its personalized learning environment initiative, Ignite 2025. A core part of this initiative is the integration of technology into its 11 schools. The school district launched a 1 device per student (1:1) scheme in 2020, providing iPads to K-12 students for media-rich learning resources to use at home and school.

With thousands of devices all connecting to the internet at the same time, the network was sure to suffer – especially at the start of lessons or when it was time to download and install operating system software updates.

CACHEBOX is Central Valley's perfect fit

Central Valley Christian Schools, a small school district in California, deployed several hundred Chromebooks for its e-learning program. However, with multiple operating system updates all downloading at the same time, the school's classroom learning was put at risk.

CACHEBOX, a purpose-built caching device, offered Central Valley the perfect solution to its problems. It picks up the strain caused by software updates while also serving learning content through the cache at much higher speeds – despite the school having less than 1 Mbps available per student.

Cache-rich sultans enjoy faster web

With an open network policy and hosting over 750 devices for students and staff, Bagdad's 300Mbps connection was routinely congested by huge software files from Windows, Microsoft and Apple, causing web browsing to be slow and unreliable.

With plans to introduce more interactive media content and further invest in digital learning platforms, Network Administrator, Gary Cummins, was concerned the district's link would not be able to cope with additional demand.

Media Library's massive impact

Childress Independent School District in Texas originally deployed CACHEBOX to deliver state testing, ensuring that tests load quickly, regardless of any other activity on the district internet connection. Since then, teachers discovered CACHEBOX's Media Library feature and its ability to provide students with online video without exposing them to inappropriate comments and links.

By providing controlled access to online video content, the district is able to block direct access to video platforms, allowing teachers to use powerful content in class without any buffering and with confidence that they're compliant with the Children's Internet Protection Act (CIPA).

CACHEBOX heats things up for Dillingham

Paying over $80,000 per month for a 20Mbps internet connection sounds ridiculous elsewhere in the US but it's the reality for many Alaskan districts, including Dillingham. Even worse than the huge bill, 20Mbps is insufficient to support over the district's 500+ devices.

A bandwidth upgrade was out of the question: an extra 30Mbps would cost them over $200k per month. This is not cost-effective and there is no guarantee that it would even prevent further congestion.

Bigger bandwidth ≠ faster internet speeds

At Lytle Independent School District the students and staff should be enjoying superfast internet access in class with 5 times what the FCC's recommends, yet they still found it slowing down during peak times.

Closer inspection confirmed that congestion was not causing the slowdown and, even if it were, a higher capacity connection was not a feasible or financially sustainable solution. Having worked with caches before at Pearsall ISD, Richard Tollett knew exactly what solution he wanted.

With the help of E-Rate funding, Lytle purchased a CACHEBOX310, a dedicated caching solution to give the school the boost it needed and now content is delivered up to 300 times faster.

Warsaw SD is saving cash by using cache

Warsaw R-IX school district in rural Missouri was struggling to manage peak-time internet demands with a 600Mbps connection and 1,500 devices connecting to the network every day.

The district was reluctant to invest in expensive bandwidth upgrades as the congestion only affected the network for short periods, usually at the start of lessons when students all attempted to access online resources at the same time. Additionally, the internet slowed down even more when over a thousand devices tried to simultaneously download new Google and Chromebook updates.

CACHEBOX saves the day

Kerrville Independent School District teachers wanted to use more online video content in the classroom. But its 500Mbps connection was not enough to support the 5,000 students on its network, and congestion was causing delays all day long.

Kerrville didn't have the budget for a bigger connection and the school needed to find a better way to manage capacity with its existing connection.

Caching beats bandwidth on Merritt

With plans to expand its 1:1 scheme, Merritt Island Christian School expected its internet traffic to grow. It needed to reduce congestion from Operating System software updates for its current fleet of student devices and control the growth in traffic from its new devices.

The school district deployed a CACHEBOX230 in 2016 to help optimize its bandwidth. Video content from sites like YouTube already consumed a large proportion of its internet capacity and after COVID, the amount of requests greatly increased. But with CACHEBOX in place, Merritt Island was able to handle the increase without the internet connection slowing down.

"CACHEBOX is the type of appliance that does its job quietly without any need to manage it to the point that the teachers and staff think the internet is simply fast, but actually I know that if we pulled it out, our internet would slow right down!"

CACHEBOX delivers instantaneous results at Louise ISD

Louise Independent School District in Texas wanted to incorporate more video content into its e-learning scheme. And with more than the FCC's recommended 1Mbps available per student, there should not have been any issues – but the school's network was not able to keep up with the amount of repeat content requests. Congestion was causing delays all day long.

With the connection already struggling to keep up with regular classroom demand, teachers feared the worst for when it was time for online testing. The slow speeds were putting students' test performance at risk and the school district needed a solution that will not only support the classroom content, but proctor caching during exam season as well.

Caching decision as easy as 51, 2, 3

Greenwood 51 – a local school district in South Carolina – needed caching to reduce the volume of large files that need to be downloaded from its internet connection and to accelerate classroom content.

As software updates were causing the most stress to its network, the district was looking for an appliance that could handle updates from multiple different operating systems as well as various different educational content providers. The right solution would also cache YouTube and support proctor caching for important standardized testing periods.

CACHEBOX is also serving online test and YouTube content:

As its network is no longer being saturated by software updates, Greenwood 51 is experiencing faster content in class, and can be confident of rock-solid access to test content.

Caching multiplies capacity for 3x devices on the same connection

When Friends Central School deployed a BYOD scheme for 800 devices in 2017, the number of devices tripled overnight. The school had planned a bandwidth upgrade to 200Mbps to pick up the increase in classroom traffic, but even a massive update would not be enough to prevent congestion caused by all the extra software updates.

Friends Central school first implemented an Apple caching device, but wanted a permanent solution that would cache all of its traffic and be compatible with multiple software vendors.

"We invested in CACHEBOX to deal with our Windows updates as they were crushing us in terms of our internet speeds and CACHEBOX helped us deal with this," says Dan Crowley, Technology Director.

Bandwidth hogs eating up your bandwidth? Let CACHEBOX give them something to chew on

With only 300 devices on a 500Mbps bandwidth things should have been smooth sailing at Rutland Independent School District. But large Windows updates were already starting to eat up the network capacity, putting plans to expand their amount of 1:1 internet devices on the rocks.

Rutland needed to manage their bandwidth-hungry content to maintain a fast classroom experience. But a state-limited connection meant that more bandwidth was not an option – and even if it were, it would only provide temporary relief until the connection was yet again choked up from the ever-growing number of large files.

In 2016 Rutland used E-Rate funding to purchase a CACHEBOX to clear congestion and deliver content at much faster speeds by using their existing bandwidth efficiently. And, when the State increased their bandwidth allocation, CACHEBOX continued to boost performance and delay the need for constant upgrades as internet traffic increases.

Dale Moeller, Tech Director, explains how Rutland's use of CACHEBOX has changed over time:

"When we first bought CACHEBOX bandwidth savings was our priority. CACHEBOX makes a big difference when it comes to reducing peak demand and allowing us to get more out of our bandwidth capacity. However, over the last years, the State has increased the size of our bandwidth connection, so now we see the most benefits from the speed increases and clearing large software updates from our internet pipe quickly."

Now in 2022 Rutland Independent School District is still happily caching along and are seeing major speed benefits from local caching. Overall, 95% of their requested content is served by CACHEBOX – now served up to 180 times faster.

x6 devices with only x2.5 bandwidth

Chapel Hill's tech director was advised by a neighboring school that buying CACHEBOX was the best investment he could make to maximize bandwidth and prevent network congestion.

This advice was soon proved true when the impact of the pandemic led to a drastic change – the district increased its number of Chromebooks for 1:1 learning from just 100 to over 600, a 600% increase.

The simultaneous demand from so many new devices in the classroom would have required a huge bandwidth upgrade. But having already installed a CACHEBOX, that was not needed – CACHEBOX handled the huge increase in device demand for software upgrades, serving the majority of requested data from local storage. Chapel Hill was instead able to make a modest bandwidth increase, from 200Mbps to just 500Mpbs – 250%.

As students returned to school with new devices in hand, CACHEBOX was there to help meet the surge in demand. Be for Windows updates, Google or Apple, CACHEBOX served up to 96% of demand locally.

Continually saving 70% and higher, CACHEBOX allowed the district to keep bandwidth low and better plan for more efficient, controlled and sustainable bandwidth upgrades, avoiding any need to upgrade network kit until it's needed.

Chapel Hill has now upgraded network switches and bandwidth to 1Gbps, and simultaneously upgraded to the larger CACHEBOX210, providing more caching capacity to match the school's higher traffic throughput and additional planned devices.

CACHEBOX saves the day at Troy Unified School District

In rural Kansas, a 1Gbps bandwidth capacity can easily cost thousands of dollars – and at prices that high, schools would want to get the best benefits they can from it. Troy Unified School District 429 thought that, with 1Gbps bandwidth upgrade that offers 3 times the FCC's bandwidth goal of 1Mbps per student, it would be getting the best internet experience possible.

However, the district still found its network congested, and upon closer inspection, network engineers discovered that Microsoft updates were accounting for over 60% of the district's internet traffic. Derek Gilbert, who had previously deployed a CACHEBOX at neighboring Riverside Unified School District, suggested they use caching to resolve their bandwidth issues.

Now, CACHEBOX is serving over 90% of Troy's Microsoft updates, up to 4 times faster from cache than the internet. The district can make use of other educational websites as well, which would have caused the network to slow down in the past, because caching is there to pick up the strain. Crucial classroom content is now served 5x, 20x, and even 45x faster.

"Even though we have a fast internet connection (1Gbps for 400 devices), there are a lot of benefits to bringing the content closer to users and serving content locally – this really improves the user experience!", Jared Pickerel, Technology Teacher, Troy Unified School District 429.

Caching delivers the high-speed content that Lakota's large connection could not

With over 17,000 students in need of faster internet speeds, and the cost of its 5Gbps connection already climbing to over $4,000, an upgrade was not a cost-effective option for Lakota Local School District.

Having already deployed ApplianSys' DNSBOX solution, Lakota investigated whether CACHEBOX could help it to avoid slow internet access caused by congestion.

Deploying CACHEBOX was all it took to transform the e-learning experience in the classroom, with content delivered to student devices up to 60 times faster.

31% of content from Google was served from cache and, as it was the cause of congestion, this freed up most of Lakota's bandwidth and ensured fast content from online learning sites like Coolmathgames and KamiHQ.

"Everything has been great with CACHEBOX – it's helping offload bandwidth to free up capacity for dynamic content," says Peter Mitchell, the Network Infrastructure Manager, "It's very much set and forget – we've had no issues and have found the general support from ApplianSys to be great!"

Improving speed at three different schools at once is no feat for CACHEBOX

In order to support classroom internet usage, the FCC recommended that school districts had at least 1Mbps per student by 2018. BUT, several years later, in 2022, Irvington Community School District was able to support its 1,037 students despite having just 500Mbps – equivalent to less than 0.5Mbps per student.

By deploying CACHEBOX and configuring HTTPS caching, they were able to avoid congestion on their internet link and improve the speed that students received content from the internet by up to 60%.

The download speeds table shows just how much of a difference caching had made for classroom content.

With CACHEBOX, latency was never an issue and school districts could make efficient use of smaller, less expensive connections. Content was served from within the district's network, at LAN speeds – and that could be many times faster than from the internet.

Double digit speed increases were common in schools and some of Irvington's content was served more than 100 times faster from cache.

Because they could access more content in class, at greater speeds than its internet connection could handle, Irvington had delayed the need for regular bandwidth updates – saving them money and turning their cache into cash.

Mansfield offloads terabytes of Microsoft traffic with caching

Mansfield Township, a 540 student district in New Jersey, had less than the 1Mbps per student target that ensures sufficient capacity to support e-learning in classrooms. It needed to boost performance to support growing use of online content in class and opted to deploy a cache for reliably fast access to e-learning content.

As part of its e-learning scheme, Mansfield relies heavily on websites like Apex Learning and Epic Books for its testing, and uses streaming services like YouTube to provide a highly engaging learning experience. The district also implemented a 1 device per student scheme (1:1), putting further pressure on its 500Mbps internet connection. Because most of the student laptops use Microsoft's Operating System, the district's internet connection would be congested any time that devices simultaneously requested software updates.

Mansfield Township deployed CACHEBOX at the end of July 2021. Just one month later, it was already seeing 96% of all content served from cache, including 99% of microsoft.com traffic. In addition to saving bandwidth, CACHEBOX also serves this Microsoft traffic 6 times faster than the district's internet connection is able. Therefore, software update traffic no longer congests the district's Internet links for long periods of time, freeing up capacity for other content to be delivered at high speed.

On average, the district has saved 96% of its internet capacity with CACHEBOX . Michael Miller, JDM Group (the district's technology partner) is very pleased with the results "Everything looks good - [CACHEBOX] is really helping with the Mansfield's bandwidth availability."

Edison offloads heavy traffic to give teachers the speed they need

Edison School District uses a combination of online learning tools to facilitate e-learning for its 1,100 students. This includes online videos and Pearson testing.

Despite paying almost $4,000/month for bandwidth in 2018, Edison SD was limited to just 100Mbps. That's just 90kbps per student, insufficient for modern web content.

At the start of lessons, teachers in classrooms across the district would direct hundreds of students to video content simultaneously. At these times, bandwidth quickly became saturated, causing slow speeds.

The district also struggled with online testing periods. The sheer increase in network traffic from Pearson Testnav caused the network to grind to a halt at this crucial time for students and teachers.

By deploying CACHEBOX, Edison SD had eliminated congestion from software updates, freeing up expensive bandwidth capacity for the content that matters to students and teachers.

Large software update files were a significant cause of network congestion for school districts. The files were often requested by the entire fleet of student devices simultaneously. At these times Gigabytes or Terabytes of software updates generated large spikes in demand, leaving little capacity for critical classroom content.

On average, the district had benefited from bandwidth savings of between 87-93% each month.

The vast majority of cached traffic comprised Microsoft and Windows updates, as well as Google video content.

Stop huge 1:1 device updates from crippling your network

Kirkwood's plans to expand 1:1 would not only replace 1700 laptops at the High School but add an extra 4,000 iPads to the network. With so many devices accessing the web, it expected a huge increase in demand for bandwidth especially for software updates.

But seeing the results of caching in similar-sized neighboring district Lindbergh, Kirkwood quickly followed suit and opted for CACHEBOX to help meet demand.

More bandwidth doesn't guarantee speed in the classroom

To secure the best e-learning experience for its students, Fowler invested heavily in bandwidth. So much so, it surpassed the FCC's 2018 'per student' target back in 2016.

Faster web access by maximizing existing capacity – no upgrade needed

With 1500 student devices regularly accessing the internet, Hollister School District's 1:1 250Mbps link was often congested. The resulting slowdown was causing significant disruption in the classroom. Teachers were struggling to use video, and with online testing coming soon, the district was worried.

By removing the need for bandwidth upgrades, Chase Raymond future-proofs its 1:1 scheme.

We've worked with many districts that have invested in student devices only to find that their internet connection cannot cope with the additional demand. The most obvious step is to upgrade bandwidth but smart districts are turning to caching for a long term, cost-effective fix.

Chase-Raymond invested in 300 iPads in order to launch a 1:1 scheme across its three schools, but with school traffic already causing frequent congestion on their 50Mbps connection, they feared any further rise in demand would quickly render the devices unusable.

Caching performance that grows as you grow

Having more than twice the number of devices to students, Keokuk's 1:1 scheme was seeing huge increases in connections from all corners of the district, as well as giant leaps in media-rich content access - both likely to push beyond their 1Gbps bandwidth capabilities.

But with CACHEBOX in place, a bandwidth upgrade is the last thing on their mind. Despite the traffic increase nobody complains of slow service. That's because up to 78% of content is served from cache, and on average, it's 10x faster than from the web - with some sites as much as 100x faster - making a huge difference in the classroom for teachers and students.

Gilmer eliminates bandwidth congestion with caching that handles all software vendor's files

Gilmer's 1:1 scheme means that up to 2,400 devices access the network many times a day. Those devices frequently request huge software update files from vendors like Microsoft and Apple.

But Terabytes of duplicate requests for these quickly congested the internet connection, resulting in slow access to critical e-learning content.

Significant annual savings with CACHEBOX

Implementing 1:1 was likely to saturate their network but a doubling of capacity would cost a further $7000 a year.

But CACHEBOX - recommended by neighbouring school Webb City - handled new levels of peak traffic, including demand for YouTube for significantly less. A one-off cost of $7k would save them $28k over 5 years, as well as postpone infrastructure upgrades.

McGregor reduces congestion, makes content faster and avoids updating its filter.

In 2017, McGregor students benefited from a very high 'per student' ratio of 721kbps - 7 times the FCC recommendation. But with increasing numbers of iPads and iMacs in daily use, and high demand for video, the network was constantly under pressure. Combined with the sheer number and size of iOS updates regularly demanded from each device, congestion was impacting the classroom.

Super BHR - constant 80%+ on a high capacity connection

Delano, an award-winning school in California, seeks the ideal learning environment for its students, particularly its in-class e-learning user experience. That's why it paid over $10,000 per month for 1Gbps bandwidth - enough to secure 236kbps per student and a responsive service.

However, the FCC had projected its 2018 need will reach 5Gbps - a significant upgrade that will require substantial additional budget. But, having experienced caching in a former role, Delano's Director of IT chose CACHEBOX to free up capacity instead, future-proofing the network.

Pyramid Lake Schools, NV

Despite its rural location and small admission of 72 students, Pyramid Lake - a public tribal school - has prioritized web access for its students. To ensure capacity for future BYOD access, it upgraded to a 100Mbps connection - but at an expensive $4482 per month.

But even before BYOD launched, the districts connection was routinely congested. Despite a 'per student' capacity of 1,388kbps - 13 times higher than the target set by the FCC - slow, unreliable web access was getting in the way of learning.

High costs for rural bandwidth limiting learning? Let a cache take the strain.

Clarksville ISD's rural Texas location meant bandwidth was expensive. Already paying more than $3k every month for 100Mbps, even a small increment would impact precious learning budget.

But with 620 Chromebook, iPad and PC users - and whole classes that accessed the same web content simultaneously - demand often spiked way above capacity. This led to congestion and slow network speeds, which impacted learning.

Caching offloads the bandwidth-hungry content today's devices demand

In suburban Queens, New York, The Mary Louis Academy is committed to providing its technology-savvy students with the best learning experience available. But, in the classroom, teachers were complaining - web access was slow, and video-buffering was a constant problem.

CACHEBOX caches everything a school needs

A growing private school district in suburban Des Moines, Iowa, DMSC handled traffic for up to 1200 users, all accessing the internet using a variety of devices - from Mac Airs and iPads, to Chromebooks to Windows PCs, as well as BYOD.

Despite having increased bandwidth from 75Mbps to 155Mbps, Information Technology Manager Jeremy Mead knew that the sheer number of devices in use could still rapidly congest the network the moment they needed to update operating software.

Only CACHEBOX can cache everything a school needs

Franklin already spent $1700+ each month for 300Mbps web access – any higher and the cost would have impacted other school priorities. Yet the addition of more user devices was squeezing capacity beyond its limits.

When more devices were added it's not just learning traffic that grew. Each device regularly downloaded sizeable files to stay up-to-date, often consuming huge chunks of bandwidth throughout the school day – severely limiting access for others.

Arkadelphia deploys caching to work within state bandwidth contract limits

Arkadelphia School District is a public schools district in rural Arkansas, with 5 schools that access the internet daily. Over 2000 devices rely on a 500Mbps bandwidth allocation provided via a state-controlled contract. However, when whole classes simultaneously accessed content in the classroom, the resulting spikes in traffic quickly caused congestion, jeopardizing learning every day.

Caching enables more devices to connect at TAFT

With web demand growing, Taft Independent upgraded bandwidth to ensure adequate connectivity. But with just 100 users accessing the web - the internet seemed slow and unresponsive.

In upgrading from to 200Mbps, Taft expected popular content from YouTube and KhanAcademy, to be much faster in the classroom. Instead, they found the network frequently congested.

Southwest Barry

Southwest Barry Community School District R5 paid $3k per month for its 80Mbps internet connection. That's $37.50 per Mbps to provide 100Kbps per student.

Besides being poor value for money, the capacity available was nowhere near what the school required at peak times.

By deploying CACHEBOX, actual peak demand had been revealed. Requests for 275Mpbs of data had been reported during peak times with CACHEBOX serving 195Mbps on top of the 80Mbps from the district's connection.

The district's CACHEBOX cost little more than 1 months bandwidth and, by saving an average 40% bandwidth, it paid for itself in just a few months. More importantly, 275Mbps of effective capacity was available to the school at a more sustainable price.

With caching at Technology Centre Du Page, annual bandwidth upgrades are a thing of the past

TAs teachers become more able and inclined to use online resources in class, a school's bandwidth requirement inevitably grows. But continuously upgrading bandwidth to meet new demand is costly and often requires changes and additional cost across the network. School Districts like Technology Center of Du Page (TCDP) in Addison, Illinois use caching to handle growth more efficiently.

Big Horn offloads big files for big savings

Like many rural districts, Big Horn County Independent School District 3 in Wyoming pays a high price for bandwidth: $3,275 per month for a 200Mbps internet connection.

Since the district deployed caching in 2017, their virtual capacity has quadrupled allowing them to benefit from up to 800 Mbps of capacity at a quarter of the price per Mbps.

Southeast Webster offloads software updates for trouble-free online testing

With a device ratio of two to every student, SouthEast Webster Grand USD was experiencing high levels of traffic demand problem that resulted in congestion, impacting lessons and raising concerns over reliability during state testing season.

But with CACHEBOX deployed speed and reliability was secured. By offloading bandwidth-intensive software updates for the district's many devices, much of the district's capacity was reclaimed. This resulted in testing season flying by without a hitch.

Slow public bandwidth bypassed with high speed caching

Orient-Macksburg Community SD serves 160 students in rural Iowa. In expanding its online learning capabilities, Orient-Macksburg's internet traffic started to overwhelm its 175Mbps capacity - resulting in slow, unresponsive classroom web access.

Alcorn lifts block on internet usage during state test season

Back in 2017, whenever state testing time arrived at Alcorn, it would instruct all other web users to disconnect, hoping to ensure fast enough access for fair student assessment. So the district upgraded their bandwidth - from 100Mbps to 250Mbps. However, with multiple online sessions taking place at the same time across the district's classrooms, access speed still suffered.

Rural Ronan's slow web speeds knocked right out the park

In rural Montana, bandwidth often comes at a high price. Ronan pays almost $2,000 for a 700Mbps connection to cater for its 1,472 students at 2 campuses. But as web-based learning and device numbers have grown, so has traffic from the classroom.

With whole classes accessing the same online content at the same time, demand regularly spikes way above capacity. Requests quickly back up, leaving students and teachers with such a slow user experience learning and student engagement is put at risk.

To cater for rising demand the FCC recommend Ronan upgrade capacity to 1.5Gbps - but such a fast connection would be too costly.

Instead, with CACHEBOX, Ronan has put their speed issues behind them, and without upgrading.

By meeting much of that high, concurrent demand from cache, core learning content is now delivered locally. And because it's served from within the LAN, it arrives at lightning LAN speeds. There's no more waiting, no more delays.

Content arrives at Mbps instead of Kbps. Learning material, as well as problematic software updates, are accelerated even faster... 49x, 141x, even 185x faster!

And by reducing demand on its current internet link, that recommended bandwidth upgrade just isn't needed – Ronan can postpone this cost hike indefinitely.

Browning School District got faster web access for less $ per Mbps

Browning Schools in rural Montana spends $3750 per month for a 550 Mbps connection to share between 2200 students at 10 sites.

With up to 800 devices connecting to the internet simultaneously, peak demand would spike to 2.4x the maximum bandwidth capacity. At peak times, the district needed 1.3Gbps - much of which was large operating system updates from Microsoft and Apple. With more demand than the network could handle, access to e-learning and video content was slow.

How much of your internet bandwidth remains after software updates?

Claremont Unified School District is an Apple flagship customer in southern California. The district's 5Gbps internet connection was routinely congested with operating system software updates. Despite most of the students using exclusively Apple products, its existing Apple caching system was only able to serve 50% of their software updates. These updates were clogging the district's bandwidth connection and leaving teachers unable to deliver their lesson plans.

Apple was unable to offer a simple and effective technical solution that would resolve the school district's connectivity issues.

Caching delivers more as usage increases

In 2016, El Dorado Springs introduced 1:1 to enable eLearning and improve student learning outcomes. But with hundreds of devices using its 60Mbps internet connection, large, duplicate software update files quickly saturated the link.

To postpone a bandwidth upgrade, the district turned to CACHEBOX. As soon as the caching appliance was deployed, those large bandwidth hogs were taken off the WAN, cached and served to students at LAN speeds – alleviating network congestion and creating more capacity for other education content.

900Mbps in classrooms with 100Mbps connection

Per-student bandwidth targets are a helpful tool for planning investment in connectivity. But purchasing more capacity isn't the most cost-effective, reliable way to deliver the bandwidth you need. As Fredericktown Local found, caching represents the best value.

If Fredericktown Local in rural Ohio was to achieve the FCC's 'per student' target of 100kbps, it faced a big leap in bandwidth costs. The district was already paying $2,600 for 100Mbps - around 85Kbps per student.

Faster content from cache keeps Peoria's students engaged

When East Peoria decided it was ready to expand e-learning across more of its core curricula and increase student device numbers, it was concerned that its 300Mbps internet connection might be insufficient.

The tech team were right to expect problems. Once the 1:1 scheme launched, they quickly found huge spikes in concurrent demand would saturate the network. Occurring whenever whole classes of students accessed the same online material individually, but at the same time - throughout the school day.

Abundant bandwidth still outpaced by caching

Snyder Independent SD has a 1Gbps connection at its High School with smaller schools connecting to it via high-speed WAN links. Thankfully the district doesn't come close to saturating its internet link, typically consuming just 350Mbps bandwidth at peak times.

With no congestion, even hundreds of simultaneous classroom requests don't cause queues for content. But despite having all that excess capacity, Snyder understood that not all content would arrive fast enough for the ideal user experience it sought. Only caching could serve its content faster.

Having deployed a CACHEBOX420 at the high school it quickly saw just how much faster. Content from domains that would previously have been delivered at 1Mbps are now reaching over 100Mbps.

CACHEBOX brings banned YouTube back to class

As Hannibal SD expanded e-learning across its 8 schools, it found its network regularly congested. With multiple users accessing bandwidth-heavy content such as video at the same time, and learning content arriving from particularly slow servers upstream, traffic would simply clog their internet link.

The result? A slow, often unusable service. With bandwidth maxed out, video would simply not load, apps wouldn't work, content would take forever to appear. Even during off-peak times the district found learning content still slow to arrive.

With teachers and students frustrated, the district was forced to ban YouTube altogether - even though teachers were keen to use it.

Having realized that increasing bandwidth again and again was never going to solve the problems, Jonathan McCammon Technology Coordinator was excited to be shown CACHEBOX via his local schools' consortium. By storing popular content locally and streaming it direct to end-users from within the LAN, huge swathes of internet demand were offloaded, and any upstream web latency is avoided.

With CACHEBOX Hannibal had dramatically accelerated learning content – it wasn't just 2 or 3 times faster, but 15, 22 even 97 times faster!

And by slashing demand on its internet link, Hannibal had freed up lots of space for more bandwidth-hungry content such as YouTube videos. Teachers were delighted to include video in lesson plans again.

Brookfield lays the ground for enhanced digital learning

Brookfield Christian School in Milwaukee serves 288 students. In addition to a dedicated computer lab for technology classes, the school has a mix of around 75 Chromebooks, Windows laptops, iPads and Apple TVs to enhance the overall digital learning experience.

Fast, free-flowing content at Black River Falls

School District of Black River Falls in Wisconsin has a 1Gbps connection shared across its two Elementary Schools, Middle School and High School, which is essential for delivering its 1:1 e-learning program.

However, with a growing number of devices connecting to the network and downloading software updates in the background, students and teachers were facing frustrating delays when accessing educational resources and YouTube videos.

Internet speeds flying at Airport

Airport Community SD in Michigan had a healthy 410Kbps per student. Yet the internet connection was proving too slow for 700+ concurrent users, causing YouTube videos to buffer. With more devices being added all the time, they deployed a web caching solution to free up bandwidth and increase web content speeds.

Internet speed 10 times faster for growing school network

At Brandon School District in Michigan, bandwidth was being eaten up by more and more network devices downloading software updates. Their options? Buy more bandwidth. Or use a cache to get more from what they already had.

The school had 3,000 or so devices registered to their network, with up to 800 connecting simultaneously at peak times. Big system updates from Microsoft and Google were consuming bandwidth, resulting in slow access to digital learning and video content. With 10-15% more network devices expected in the coming years, the situation was likely to get worse.

Trinity School slashes peaks

The introduction of additional student devices puts pressure on existing internet connections. But, as the tech director at Trinity School could see, growth in demand would continue to grow long after the devices are first deployed. Like other districts, Trinity School needed a long-term solution.

Trinity introduced an independent learning scheme in 2016 to help stimulate student engagement and improve learning outcomes. However, upon launch, students found the internet slow and unresponsive, threatening the engagement levels the school was hoping for, and lesson plans suffered.

Faster content, by an order of magnitude

The data from Laurens County in South Carolina illustrates the order of magnitude of speed at which a cache can serve up content quicker than the Internet. It also shows that, even in upgrading to multi-Gigabit links, schools cannot accelerate content that is inherently slow at the server source or is delayed by latency.

When Laurens decided to roll out 1:1 learning to each of its 9 schools it chose to upgrade bandwidth to 1Gbps to ensure capacity. That equated to 175kbps per student, nearly double the FCC 2016 'capacity per student' target. However, in daily use, it still found content was too slow in the classroom, including core lesson content. One particular favorite - CoolMath - was not responsive enough to be an effective learning tool.

North Ottawa Lions roaring about CACHEBOX

When bandwidth is prohibitively expensive, caching is a financial no-brainer. But even if connectivity prices fall dramatically, the evidence from North Ottawa shows that caching is an essential tool for delivering fast classroom connectivity.

In rural Kansas, North Ottawa County's 600 students relied on 100Mbps to access learning content at a cost of $1,475 every month.

But with CACHEBOX, an average of 69% of all district content was delivered locally from cache storage. Users needed to access the internet link for just 31% of requests. The district effectively satisfied demand with just 50Mbps capacity and could have saved around $9000 per year.

A few years on and North Ottawa decided to upgrade bandwidth as part of a wider 1:1 initiative. Thanks to lower costs a giant leap to 1Gbps was feasible and the district chose to upgrade its CACHEBOX to handle this higher throughput. Why? North Ottawa had seen first hand CACHEBOX's ability to serve content at LAN speed regardless of the availability of upstream bandwidth.

Only CACHEBOX can guarantee that education content reaches students faster.

Sioux Central eliminates start-of-lesson peaks

Peak demand at the start of lessons meant Sioux Central Community SD internet link was often congested and painfully slow to use. Teachers reported that students trying to download the same video at the start of a lesson needed to wait for several minutes before being able to watch a single minute.

Before CACHEBOX - its 35 Mbps internet connection was saturated for much of the school day.

Equitably faster online learning county-wide

Because of its huge geographic span, 220 of Miami-Dade's schools are remote, with typically smaller rural Internet connections.

For many rural students access to the district's online learning platform was so slow they were waiting as long as 30 seconds for a page to load. Constant traffic congestion from duplicate learning requests would see lost learning time rapidly reach many minutes in just a single lesson - putting those students at a disadvantage to those with access to larger connections.

After installing CACHEBOXes, Miami-Dade found 97% of requests for learning content being served from cache. With that content being served locally - at LAN speeds - load times were drastically slashed.

A classroom of 30 students used to waiting 30 seconds for a page to load saw that drop to just 2.45 seconds.

In serving the vast majority of content from cache, congestion had been eliminated - freeing up precious bandwidth - enabling the 3% of dynamic content not served from cache to also load much faster.

Miami-Dade's results show how caching can help provide equitable access to accelerated e-learning in remote schools.

Learning platform without caching: 30 requests * 1 second for each = 30 seconds load time.

Learning platform with CACHEBOX: 29 requests at 0.050 seconds each + 1 uncacheable file at 1 second = 2.45 seconds load time.

Oak Grove cuts bandwidth requirement

A 40% Byte Hit Ratio (BHR - the ratio of internet requests that were duplicates and could therefore be served by CACHEBOX) in May 2017 meant that only 356GB of 592GB content accessed within the school came from the internet.

Durant can balance bandwidth and caching to deal with huge traffic spikes

Like many schools, the amount of bandwidth that Durant needs during peak demand is many times higher than it needs most of the time. However, Durant's situation is worse than most and, due to its rural location, the cost of bandwidth is extremely high.

The school had 85Mbps and needed around 120Mbps on average during the school day. At peak times it needed almost 700Mbps. At the $50 per Mbps that the district already paid, Durant would need to spend over $30k per month extra!

By investing $7,000 in CACHEBOX230 Durant had been able to serve up to 682Mbps with just an 85Mbps connection.

The district could make a far more cost-effective investment in additional bandwidth of $4250 for an extra 85Mbps. In this case CACHEBOX would have paid for itself in less than one month and saved the district over $300k per annum:

Annual cost to serve peak demand without caching: $30k x 12 = $360k

Annual cost to serve peak demand with caching: $4250 x 12 = $51k

Annual bandwidth cost saving ($360k - $51k) = $309k

Total saving ($309k) - cost of caching ($7k) = $302k pa

Woodland can reach FCC target at a fraction of the cost with CACHEBOX

Setting per-student bandwidth targets is a smart way to plan bandwidth requirements. But meeting your targets shouldn't be a question of simply purchasing additional capacity. Caching will enable you to deliver target capacity reliably and cost-effectively.

With just 250Mbps shared by 6190 students, Woodland School District 50 is some way below the FCC's 100Kbps per student 2016 target. To reach this target, the school would need a further 370Mbps which, with their current supplier would cost an additional >$2000 per month.

Fortunately, as a long-time CACHEBOX user the district knew that, on the occasions that demand exceeded 250Mbps, CACHEBOX would be able to help. The graph below shows that, for the majority of the time, 250Mbps was sufficient to handle demand. At times, they have needed 650Mbps which is just over FCC target at 110Kbps per student. Caching had bridged the gap at a fraction of cost of doubling the bandwidth all year around to manage the handful of occasions where it was needed.

Highland's students get faster priority classroom content

In a rural setting, Highland Local Schools would struggle to meet the FCC's 100Kbps per student target without spending a very large proportion of budget on bandwidth capacity. Fortunately, CACHEBOX offers a smarter way to guarantee fast content to students.

By storing content locally and serving it from within the LAN, Highland Schools avoid the potential causes of slow content like network congestion or a content provider's slow web server.

CACHEBOX outruns 10Gbps bandwidth

With a student population of approximately 30,000, Anaheim is one of the largest school districts in California, with Internet throughput to match. But as an urban district, Anaheim has access to cheaper bandwidth - they pay the same price for 10Gbps that a rural Texan district pays for 50Mbps.

That puts Anaheim's bandwidth capacity per student way above average - so students shouldn't suffer the effects of network congestion. However, even at 400Kbps per student (4 times the FCC's 2016 target for schools), Anaheim's students still find web content arrives at sub-optimal speeds.

The download speeds table shows classroom content from the internet arriving at vastly slower speeds than the network can handle. This can be due to any number of issues upstream and beyond a schools control.

But with CACHEBOX latency is never an issue. Content is served from local cache, at LAN speeds – and that can be many, many times faster than from the internet.

• Apex Learning is served 48x faster from cache
• Sparknotes is served 35x faster from cache
• Primarygames.com is served 27x faster from cache
• Historyonthenet.com is served 10x faster from cache

Even with 10Gbps link that is underutilized, it is caching that delivers the responsive browser that the classroom demands

Glenbard reclaims capacity for education content

With a mix of Apple and Windows devices in use by over 8000 students and staff, software updates make up well over half of all Glenbard's internet traffic.

Large update files are a significant cause of network congestion for school districts. The files are often requested by the entire fleet of student devices simultaneously causing large spikes in demand and leaving little capacity for other content.

By deploying CACHEBOX, Glenbard has eliminated the software update bandwidth hog, freeing up expensive capacity for the content that matters to students and teachers.

The table below highlights that Apple alone consumes 55% of all traffic. Some software vendors provide their own caching solutions but, to support environments with kit from multiple vendors (like Glenbards), network admins would need to manage a collection of caches and wouldn't improve the performance of education content.

BYOD enabled for Pickens County

Pickens County serves 16,200 students across 16 elementary schools, 5 middle schools, and 4 high schools, covering an area of 504 square miles.

The district wanted to implement a Bring Your Own Device scheme but needed to ensure that congestion would not cause slow internet, damaging student engagement in class. Pickens County consulted with neighboring school district Laurens County and, impressed with their bandwidth saving solution - CACHEBOX - deployed their own.

With CACHEBOX, Pickens was able to support over 7,700 devices on its 2Gbps bandwidth link, including student and staff laptops, desktops and interactive Promethean boards. BYOD had been fully enabled without congestion, and rather than delays in content delivery, speed in the classroom had increased.
