University of WashingtonComputing & Communications Scope of UW Networking UW Campus Networks –Seattle –Tacoma –Bothell/CCC Medical Centers (net design) –UW Physicians Network –UW Medical Center –Harborview Medical Center Pacific/NorthWest Gigapop –Pacific Wave exchange point –Pacific Light Rail Statewide K20 Network

University of WashingtonComputing & Communications Baseline Connectivity Shared 10Mbps HD Switched 10Mbps HD Switched 10/100Mbps FD –backed by GE switch/router infrastructure Goal: Switched 10/100 FD for all; GE for a few Reality: Cat3 wireplant upgrade will take multiple years and multiple millions of dollars
5
University of WashingtonComputing & Communications Advanced Services Multicast –Partially deployed –Older routers need to be replaced QoS –Laissez faire? Premium service? –Best with FD connections. VoIP –Needs QoS, extra-high availability –POE desirable; implies UPS in closets IPv6
6
University of WashingtonComputing & Communications Premium Services? Wide-area QoS chargeback? Preferred access to Internet for a fee? Lots of interesting policy and tech issues...
7
University of WashingtonComputing & Communications Mistakes We Didn't Make FDDI to the desk VLANs ATM Various "cut-thru IP switching" digressions Claim: Staying with pure IP and Ethernet has served UW very well...

University of WashingtonComputing & Communications Current Statistics Avg Backbone traffic: nearly 2 TB/day Peak Inbound traffic: 100 Mbps (40 in 1999) Peak Outbound traffic: 160 Mbps (20 in 1999) Doubling time: Less than 2 years!! Hosts: over 50,000 Modems: over 2,000 Switched subnets: 70% (30% in 1999) 10/100 FD subnets: 25% (5% in 1999) Cat 5 buildings: 10%

18
University of WashingtonComputing & Communications Recurring Theme: Explosive Growth More users More devices Longer use New (bandwidth-intensive) applications –e.g. remote collaboration tools –audio/video streaming –tele-immersion –distance learning
19
University of WashingtonComputing & Communications Networking Hot List Campus building/subnet upgrades Backbone upgrades (production, experimental) Regional networking Internet 2 Network Hardening Security Advanced Services Wireless Management/diagnostic tools
20
University of WashingtonComputing & Communications Some Success Metrics 10/100 FD connections: xx% Multicast deployment: xx% QoS deployment: xx% Dept’l wireless coverage: xx% Router center hardening: xx% Backbone capacity IPv6 capable routers
