CAMPUS NETWORK UPDATE Terry Gray Director, Networks & Distributed Computing UW Computing & Communications June 1999

A Look Back Oct 1988:Ordered first Cisco campus router May 1989:Solve DECnet problem via TGV Multinet license Aug 1989:AutoIP deployed Jan 1990:Became NOC for NWNet (replacing BCS) Nov 1990:Began evaluating 10BaseT Ethernet Mar 1991:Began deploying 10BaseT Ethernet May 1992:Dual apex network topology deployed Jun 1992:Began transition to OSPF routing Sep 1992:Last host removed from original "flat" campus Ethernet Oct 1992:Began DialIP (PPP) project Jan 1993:Completed transition to OSPF routing Mar 1993:First MBONE deployment Jul 1993:Retired Micom switch Jun 1994:Completed NWNET transition to OSPF May 1995:Adopted quad backbone topology May 1995:First DHCP deployment Jun 1995:DialIP (PPP) service finally rolled-out

More... Feb 1996:First 100Mbps Ethernet deployment Apr 1996:SNNAP conceived Mar 1997:NWNet acquired by Verio Apr 1997:USNO Stratum-1 GPS timeserver deployed Jun 1997:First fiber between UW and Westin operational Jul 1997:SNNAP switches deployed Sep 1997:SNNAP "operational” Dec 1997:AutoIP retired Jan 1998:Surveyor net monitor deployed for Advanced.org Jan 1999:AMP net monitor deployed for NLANR/MOA May 1998:First use of metropolitan Gigabit Enet (Westin ) ??? 1998:First drop-in authenticated net connections Sep 1998:UW connects to vBNS backbone Sep 1998:UW connects to Abilene backbone Nov 1998:K20 Phase I complete (9 ESDs connected) Sep 1998:PNWGP "operational" Jan 1999:Verio connection to SNNAP operational Jan 1999:Retired last Cisco AGS campus router Apr 1999:Deployed first Gigabit Enet on campus

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...

Future Milestones July 1999:UW ceases to be NOC for Verio/NWNet July 1999:4th commodity Internet DS3 Aug 1999:K20 Phase II complete (296 districts) Sep 1999:First DWDM deployment Oct 1999:Survive Fall Internet 2 meeting Oct 1999:Campus-wide multicast support Fall 1999:V.90 modem pool upgrades Phase-out last Cisco AGS MAN/WAN routers Deploy separate experimental GE backbone Network hardening -especially in HS First host connected at GE First VoIP First HDTV over IP Dynamic DNS deployed First use of DiffServ/QoS First MPLS virtual circuit deployment 10b2 phase-out Web-based realtime performance monitoring Continuous MPEG2 stream available and usable on campus Availability of wireless on campus A better solution to authenticated network access

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

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: – For upgrades, prefer to do entire subnets Current pricing: –$100/port for switched 10Mbps/HD –$200/port + cat5 infrastructure cost for 10/100 FD
