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

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

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

Premium Services?
• Wide-area QoS chargeback?
• Preferred access to Internet for a fee?
• Lots of interesting policy and tech issues...

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...
