Where To From Here?
Question/Comments

3. 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)....

5. Current Services Set

6. 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

7. 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

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

11. 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”

12. 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

13. 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

14. Questions/Comments?
Thanks!
