Presentation Transcript

  1. CAMPUS NETWORK STATUS/FUTURES Terry Gray Director, Networks & Distributed Computing UW Computing & Communications October 2001

  2. 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

  3. Pacific Northwest Gigapop

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

  7. 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...

  8. 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%

  9. UW-S Building/Subnet Status

  12. Number of Devices

  13. Backbone Traffic

  14. Border Traffic 1999 (2 day)

  15. Border Traffic 2001 (2 day)

  16. Border Traffic 2001 (6 hour)

  17. 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

  18. Networking Hot List • Campus building/subnet upgrades • Backbone upgrades (production, experimental) • Regional networking • Internet 2 • Network Hardening • Security • Advanced Services • Wireless • Management/diagnostic tools

  19. 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

  20. Questions? • Or comments… • Or complaints...
