The Challenge
Cisco has a similar story, with a proprietary system
blog.sflow.com -> peter files musing
sflow.org to see if equpment supports it.
bgp stuff at oboarder, vs netflow?
sflow allows full bgp + as paths to be sent
very high-value measuremnt, to look at as paths and peering arrangment
allow you to break down by ip addr, subnets, protocols, min myb min
pull for accounting and routing perf
if routers don't support htat, can peer with router and pull aspaths in
and splice in to sflow/netflow feed, and do similar analysis
wan pov, realtime access allows for attack analysis
so a reason to find into wan routers as well as l2 switches.
