Total number of users in dorms? 7,500 Total Internet bandwidth reserved for residence halls (to your ISP): No bandwidth is reserved specifically for the residence halls. Do you have a cap (Mbps) per users? If so, at what speed? More MB/week-- we utilize weekly bandwidth accounting. Students purchase a tier of service of service, and are unlimited in speed unless they exceed their allocation, then are reduced to modem speeds until their weekly reset or they purchase a higher tier (no harm/no foul). This is for all students resident/commuter. Resident tiers are priced/packaged differently due to their greater consumption patterns (to avoid subsidies). If you cap, do you set it at the switch port using QOS (wireless controller for wireless) or use an appliance such as a Packetshaper or Firewall? When do you decide to upgrade your bandwidth? When you hit 80% or do you wait until you bump up against your limit? If your connection is over 1 gig to your ISP, are you using a 10Gig handoff or multiple one gig handoffs bundled together? We pay for a committed rate of ~5Gbps at the 95th percentile for the entire campus, however have two 10Gbps ports to our provider due to bursty traffic which will occasionally exceeds 10Gbps. The residential service pays for its portion of use. That is calculated across all wired and wireless consumption on campus by their users (not just in the residence halls).
When to worry is a bit more complicated given access rate versus committed rate -- and also sampling rates. I drive the committed close to 100%. Access, depends on the price, 30% if you can afford it. But looking at short-term sample rates may indicate otherwise (1, 10, 30, 60 second samples). -William ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
