York University has a 1 Gbps connection to ORION (the Ontario provincial
Research & Education Network), and 300 Mbps to cogent. We shape the cogent
traffic using a Packetshaper 10000. During peak periods this box is very
busy, although the box isn't overloaded, I would be concerned about putting
more bandwidth through it. The packetshaper is pretty good at P2P
identification, but as is the nature of the game, it's almost always one step
behind the P2P coders who are purposefully looking for ways around shapers.
And encryption is making this even harder.
If I was purchasing today I'd probably look at the following vendors:
Ellacoya - this product seems to be focused towards and popular with
broadband ISP operators (which in many ways is what university network
services groups have become).
Cisco Service Control Engine - which is also targeted at broadband ISP.
