1 January 2003 CSG Meeting Terry Gray University of Washington
Bandwidth Management January 2003 CSG Meeting Terry Gray University of Washington

2 Issues Preventing illegal activity Protecting legit activity
Moral grounds Legal liability Protecting legit activity Containing costs My job is to focus on the last two

3 Options (I2 BW BOF) do nothing per-IP quotas (rate-based)
per-IP quotas (volume-based) per-class quotas (rate-based) per-class proportional sharing per-IP proportional sharing usage-based charges after quota per-application quotas (rate-based) outsource res hall networking block servers via NAT or firewall

4 UW ResHall Policy Block incoming to usual TCP server ports
Spring 2002: note BW costs escalating Fall 2002: Commodity Internet caps Incoming p2p to 20Mbps Outgoing p2p at 2Mbps Max for all traffic = 100Mbps I2 and campus traffic not capped

5 Results Initial uproar has subsided… Replaced by Guerilla warfare
Increasing "unclassifiable" traffic 10 Mbps of "Ident" traffic Currently few complaints Need to examine campus and I2 traffic

6 Future ResHall: usage-based charges???
Campus: two-tier subscription model?? For sure: more complexity
