Does streaming music, downloading files and surfing the Web seem
faster on campus? CIT has recently implemented two new on-site
content distribution networks (CDN), which offload university
Internet bandwidth and provide faster response times.
CIT deployed two on-campus caching systems during summer 2012.
Google Global Cache speeds up Google services, including news, maps
and search. UB also recently partnered with the Akamai Accelerated
Network, which provides content for many popular sites, including
CNN. While each vendor maintains their servers remotely, UB
provides space, cooling and power for the CDN edge servers in our
As a result of these CDNs, website response times at UB have
significantly improved, with download speeds up by approximately
400%. Having an on-site CDN also allows Internet bandwidth
reductions, providing savings over time as caching rates continue
to increase. Through the caching initiative, UB is saving
approximately 300Mbps at peak, which translates to 20% of the total
bandwidth used. As demand for high bandwidth media grows, so does
the benefit to UB.
The on-campus CDNs were recently put to the test on September
19, when Apple released their latest version of iOS software.
Universities across the country saw their Internet bandwidth
skyrocket, causing slowness and visible outages. During this
timeframe, the cache at UB served close to 1Gbps, with the Internet
link remaining unaffected.
