Perhaps students are not average users, but our Resnet currently has: * Approx 2000 connections, most at 100 Mbps. * These are divided into 4 areas, each area is connected with 1 Gbps to central location (so on average you could say we have 500 users sharing a 1 Gbps link) * Central location has 10 Gbps uplink; stats for this link over the last 7 days at 10-min average polling interval are: in: min 422 Mbps, avg 883 Mbps, max 1570 Mbps, 95th pct 1250 Mbps. out: min 48 Mbps, avg 272 Mbps, max 571 Mbps, 95th pct 459 Mbps.
Perhaps these numbers can be used as an indication for your sizing/design.
Most useful response so far, thanks very much :) adam.
