Agenda History Current Service Set/Statistics What’s New Where To From Here? Question/Comments

History Routeviews started life as a purely operational tool We needed a way to look at how operators saw our routes Randy Bush was kind enough to give me a view from one of his MAE-WEST routers People started using routeviews and contributing views But this is what caused things to really take off (circa 1993)....

Current Services Set

A Few Statistics 2 Cisco VXRs (cli access) 8 Zebra Collectors Soon to be BGPmon (see bgpmon.netsec.colostate.edu) Realtime (telnet://routeviews.routeviews.org) takes O(10K connections/day) > 12 Tbytes of archived BGP data Both MRT and ‘sh ip bgp’ formats Earlist archived data circa 1997

A Little More on What’s Archived Collect RIBs in 'show ip bgp' format Collect MRT format RIBs and updates Repository is O(12 TB) and growing at 9%/month BGPMon will add XML format RIBs/UPDATES Working on database front-end(s) Goal is to enable data mining/visualization

What’s New This visualization of the characteristics of IPv4 WHOIS data was created by The Measurement Factory under subcontract to CAIDA.

What’s New... BGPMon http://bgpmon.netsec.colostate.ed u XML Format RIB/UPDATEs “Real Time” More Collectors Long term archival storage Google/Yahoo “Mirrors”

Issues Zebra/Quagga suitablity/stability eBGP Multihop Code base split into two trains Single threaded: Dumper thread procesing causes BGP keepalive timeouts MRT’s one second granularity -- suffiient? And MRT bugs :-( Hope BGPMon solves many of these issues eBGP Multihop Some routers don’t do eBGP multihop well Can’t study events between speaker and listener

Issues Large scale archivial data storage/access A perennial problem Operations Running routeviews is like running a “control-plane only” ISP All the same problems And as always, funding and person- power issues
