University of WashingtonComputing & Communications Topics Scope Services Stats –Subnets –Devices –Traffic –P2P/Dorms –Dialup Wireless Security Monitoring Upgrades Failures Trends Priorities

University of WashingtonComputing & Communications Scope of UW Networking Campuses –UW-Seattle –UW-Bothell –UW-Tacoma Medical Centers –UW Physicians Network –UW Medical Center –Harborview Medical Ctr MyUW.net Service PNW Gigapop –Peering / Exchange (Local, National, International) –Transit ( Regional, Commodity, Internet2, PLR/NLR ) K20 Network –K12 –2yr colleges –4yr colleges –Libraries

University of WashingtonComputing & Communications Baseline Services Shared 10Mbps HD Switched 10Mbps HD Switched 10/100Mbps FD –backed by GE switch/router infrastructure Goal: Switched 10/100 FD for all; GE as needed Reality: Cat3 wireplant upgrade will take multiple years and multiple millions of dollars

University of WashingtonComputing & Communications Advanced Services Multicast –Harder than it looks –Enabled on ~ 200 subnets –Older routers/switches can’t handle QoS –Moot on 10Mbps (half-duplex) subnets –No substitute for adequate provisioning –Probably use in K20 network first IPv6 –Native: not yet

University of WashingtonComputing & Communications Traffic: Backbone

University of WashingtonComputing & Communications Traffic: Border Sample from yesterday: AVERAGE MAXIMUM INBOUND: 83Mbps 162Mbps OUTBOUND: 223Mbps 400Mbps

University of WashingtonComputing & Communications Dialup Users

University of WashingtonComputing & Communications Dialup Use

University of WashingtonComputing & Communications P2P and ResHall Traffic Traffic levels out of control Dramatic increase this year Violation of existing server policy Substantial cost implications Cause: P2P music/video sharing Solution: Packeteer bandwidth manager

University of WashingtonComputing & Communications Wireless Pilot successful DIY secure WAPs? g just approved a affordable

University of WashingtonComputing & Communications Security Logical Firewalls: success stories Evaluating other subnet options Secure server sanctuaries Host-based firewalls Protecting the network devices

University of WashingtonComputing & Communications Network Monitoring For diagnosis, capacity planning, accounting HP OpenView upgrade Asta product: top-talkers Homebrew tools, e.g. –netflow graphing –port-based accounting –Layer2 device monitoring –automatic database synchronizer Still need better “Finger Pointing Tools”

University of WashingtonComputing & Communications UW Network Upgrades DHCP servers –New hardware –New software: better failover –Longer leases: better stability Evaluating replacement routers –Foundry and Cisco Dialup –V.92/V.44 support –RADIUS authentication

University of WashingtonComputing & Communications Ouch: some failures A few partial backbone switch failures Masked by redundant backbones Excessive errors on optical interface Impact: intermittent application failures Action: improved monitoring tools

University of WashingtonComputing & Communications Pacific Northwest Gigapop

University of WashingtonComputing & Communications PNW Gigapop

University of WashingtonComputing & Communications PNW Gigapop Services Peering / Exchange –Local (e.g. ATTBI, Microsoft) –National (e.g. ESnet, DREN) –International (Canada, Taiwan, Australia) Transit –Regional (Intra-Gigapop) –Commodity Internet –Internet2 (Abilene) –PLR/NLR

University of WashingtonComputing & Communications NW Local Exchange Points Seattle –SNNAP/Pacific Wave (500Mbps!) (UW benefit: 200Mbps/ $30K/mo) –SIX –PAIX Portland –NWAX

University of WashingtonComputing & Communications PNW-GP Upgrades Commodity Internet –Doubling capacity to 3Gbps –Three providers: Level3, Verio, C&W –Substantial cost reduction! Internet2 -NG –Link upgrades: 2.5 -> 10Gbps –Gigapop router upgrades: Juniper T320
