inter-domain routing (BGP) data  


not much instrumentation/diagnostics/data sources
UO's www.route-views
RIPE's www.ripe.net/ris
Merit's IPMA /www.merit.edu/ipma
really need real-time instrumentation
(w/o impacting forwarding performance)
ideal: route-lookups in real-time w/o kernel
need data for realistic inter-domain routing models
identification/vis of flaps, outages, critical pts
correlation of perf. w/some measure of path `length'
comparison of forward path with
BGP path
shortest path
reverse path
