Hello Bill We have a total of 6000 student rooms connecting to our core over a number of 1Gb leased lines. These feed into a Cisco 6509 which aggregates the data and connects to our firewall through a 10Gb connection.
The traffic is passed through a Tipping Point device prior to being passed out of the firewall and into the internet on a single 1Gb connection. The Tipping Point is primarily used for P2P policing. Each user is limited to 4Mb down and 1Mb up, implemented through per-user microflow policing on the 6509. We have had a maximum of 732Mb being generated from the residences, with the daily average being 385Mb.

We currently have two 100Mb diverse Internet connections. We have about 3500 students in our campus residence village and another 500 at remote residences. The individual residences each have a 10Mb fiber back to the campus but that's a discussion for a different day. Most of the wired and wireless traffic from the on campus residence halls is directed to one of the 100Mb links while admin, faculty and some other small student population uses the other. We use Packeteer to rate limit and the two links are pretty much maxed out for a good part of the day and night. I'm curious at to what bandwidth some of the other universities have and also what type of management policies and techniques people are using. Thanks. Bill William F.
