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

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

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...

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

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