IPTV

Lancaster University has invested £5m to upgrade its network in order to cope with increasing demand on bandwith and to provide IPTV and VoIP services.

The University plans to film lectures and broadcast them over the network directly to students’ PCs and laptops, significantly increasing traffic volumes.

Infrastructure improvements include the installation of Category 6 cabling, together with ‘Big Iron’ RX backbone switches with 10Gbyte upgradeability, IPv6
compatibility and multicast capabilities, supplied by Foundry Networks.

The upgraded network is capable of sustaining high bit rates and can deliver up to 10gbps feeds to 15,000 students in different buildings on the campus, The old 100mbps network was demonstrating high levels of latency, jitter and packet loss when using applications such as video.

The University has introduced a rating system which helps it to manage bandwidth. The system identifies the areas of heaviest use and can determine whether the network is being used for activities such as illegal downloads of films.

Network managers can then implement immediate measures to prevent such activities.
