1 State of the Network 1 May 2007 Computing Support Meeting Terry Gray Assoc VP, Technology & Architecture C&C

> 2007

Recent Changes  Expansion, both wired & wireless initiative  Router upgrades (Foundry -> Cisco)‏  Core/Backbone: Layer 2 -> Layer 3, 10Gbps  Network Information & Security Tool portals (Beta)‏  Spanning Tree deployment (just beginning)‏  Tipping Point & Packeteer upgrades  Building & Outside Plant upgrades  Metropolitan Ethernet transport system  First 10GE connections (HDTV & Imaging)‏

Growth... (except for modems!)‏

Modem Users -a dying breed

Devices Seen on Network (adjusted)‏

Campus Backbone Traffic >40TB/d

Perimeter Security  Firewalls  DIY Logical FWs ( >70 on campus)‏  Managed subnet FWs (new svc, using Cisco FWSMs)‏  P172 (private addresses plus NAT)‏  IDS/IPS  Tipping Points  Homebrew, based on Netflow data  Dark net monitoring  Also, supporting host security:  Vulnerability scanning  Managed host service (Nebula)‏  Security tools portal  UW Policies: computer & data security standards

Trends...  Growth continues (speed, capacity)‏  Higher availability expectations  More wireless/mobility  More convergence (e.g. VoIP, video)‏  More TDAs (Traffic Disruption Appliances)‏  More “gated communities” (aka “Balkanization”)  Backlash/Consequences  Complexity/MTTR challenges –harder to diagnose  More tunneling & encryption  FutureNet = local nets linked together by Port 443  More “personal lambda” & “bypass” nets  More SSL VPNs to get around security

Immediate Focus Areas  Wireless Initiative, year 3 (remaining 40%)  Stability: router upgrades, spanning tree  Improving diagnostic & management capability  Self-service tools  Improved security visibility and reporting  Next-Gen network requirements gathering

Future Needs / Requests  More and fewer security/admin perimeters  Abandoning traditional geographic topologies  More/faster wireless; n, UWB, etc  Building upgrades (40-50 need it)‏  More visibility into traffic, incl. trend analysis  Perimeter defense bypass  MAC Registration (at least wireless)‏  Network Admission Control (wired)‏  Traffic shaping, by application  Separate and/or faster nets  Jumbo Frames  Dynamic DNS  IPv6

Questions/Comments  At the break.... or via 
