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...

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?

13
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"

14
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

15
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

16
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...

17
Who You Gonna Call?

• For installation or upgrade
• install_at_cac.washington.edu
• 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
