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 500 GB/day
Peak Inbound traffic: nearly 50Mbps
Doubling time: 1.3 years
Hosts: nearly 40,000
Modems: over 2,000
Backbone Traffic -Linear
Backbone Traffic -Log
Number of Hosts
Border Traffic
How will we use the bandwidth?
• Aggregation: more users, longer use
• Old Apps going faster
• New Apps previously impossible

Enabled by Middleware
Will NetMeeting one day be usable?
Bulk VoIP?
HDTV over IP?
Advanced Services, anyone?
• Multicast
– Deployed on 16% of subnets
– Waiting for new router software
– Target: Oct 99, but more testing needed
• QoS
– Planning underway
– Whitepaper "Real Soon Now"
Baseline Services
• Shared 10Mbps HD
• Switched 10Mbps HD
• Switched 10/100Mbps FD
– backed by GE switch/router infrastructure
• Goal: Switched 10/100 FD for everyone…
• Reality: Cat3 wireplant upgrade will take
multiple years and multiple millions of dollars
Building/Subnet Status
• Connected buildings: 150
– Category 3 = 133
– Category 5 = 17
• Buildings with 10/100 FD and GE backing
– Physics/Astronomy (6 subnets)
– Soon: new Fish/Ocean (6 subnets)
• Departmental subnets: 278
–

–
–
Shared 10 = 208 (23 soon to be sw 10)
Switched 10 = 58
Switched 10/100 = 12
So: 1/3 of subnets (93/278) switched by year-end
Premium Services, Anyone?
• Wide-area QoS chargeback?
• Subscription ($$$) services?
– Switched 10 with expedited forwarding?
– Switched 10/100 with expedited forwarding?
• Lots of interesting policy and tech issues...
Who You Gonna Call?
• For installation or upgrade:
– [email protected]
– 543-5068
• For upgrades, prefer to do entire subnets
• Current pricing:
– $100/port for switched 10Mbps/HD
– $200/port + cat5 infrastructure cost for 10/100 FD
Hot List
• Campus building/subnet upgrades
• Regional networking:
K20, SNNAP, PNWGP, UWPN, CCA...
• Network Hardening
• Network Security; Access control
