It's also probably helpful to use SNMP to verify that the data you're getting from netflow is at least somewhat accurate and that the routing changes are actually effective in getting the desired results.

We were using Internap, but ended up writing our own so that we could look at larger number of speakers. The technology is not that complicated, you basically take netflow data and send it to a host that has tunnels over each one of your BGP peers that you care about. It then uses a combination of traceroute and ping to collect its data that is then injected back to the router over BGP. ><> Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com
