  1. Interdomain Routing Streams Timothy G. Griffin AT&T Research griffin@research.att.com Z. Morley Mao UC Berkeley zmao@cs.berkeley.edu MPDS 2003 June 7, 2003

  2. Architecture of Dynamic Routing IGP EGP (= BGP) AS 1 IGP IGP = Interior Gateway Protocol Metric based: OSPF, IS-IS, RIP, EIGRP (cisco) AS 2 EGP = Exterior Gateway Protocol Policy based: BGP The Routing Domain of BGP is the entire Internet

  3. How Many Routes? Thanks to Geoff Huston. http://bgp.potaroo.net on May 30, 2003

  4. Update Rates

  5. Something went Bump!

  6. Naughty, Naughty Routes!

  7. Worm Holes in the Control Plane!

  8. Questions • What is a “BGP routing anomaly”? • Can we express BGP anomaly detection as stream query? • Can these be expressed as stream queries: • Update counts (Yes, of course!) • RFD Penalties? • BGP Table?
