Transparent Caching for University Campus Networks
University students are high-volume consumers of Internet bandwidth. Demand for viral videos, file sharing, software updates, gaming, Netflix and similar entertainment services all combine to put a constant strain on the network. Data from PeerApp customers suggests that streaming video alone consumes up to 70% of universities’ network bandwidth. Meanwhile, the student community expects high quality broadband service and the University’s data network is even touted as a selling point to prospective students, faculty and researchers. University IT professionals need strategies that help them cost-effectively cope with this constant traffic growth.Transparent caching helps in two ways. First, it reduces network costs associated with constantly having to expand the campus network and Internet transit links. Second, it improves the end user experience. Transparent caching achieves both by automatically detecting popular content and serving it from within the campus network.
PeerApp’s UltraBand is usually installed at the Internet transit point of campus networks, but it can be deployed anywhere within the IP network. UltraBand scales from high-density systems designed for large sites and centralized deployments to appliance systems for smaller campuses and distributed deployments. In fact, UltraBand has been designed to meet the requirements of global telecommunications network operators so its scale, security, and reliability meet and exceed campus network requirements.
UltraBand connects to the University network via existing network elements using policy-based routing or a deep packet inspection (DPI) switch.
The PeerApp Impact"Rather than put students on a digital diet, network administrators at UCSB shifted a third of repetitive and high-bandwidth traffic to PeerApp's local cache. The move boosted network speeds and saved money by slowing expansion of the pipe."
