This may be more than you're looking for: http://www.renesys.com/ Very detailed analysis of peer connections. A bit spendy, but I had a demo license for a while and found it incredibly useful. If you run an ISP with clueful customers who demand to know what's going on, it's worth the investment to back up your statements. JT On Aug 20, 2010, at 9:03 AM, David Hiers wrote:
Come to think of it, I've been more annoyed in the past month or so...
Anyone know of a tool that can maintain/display a traceroute-like history? Not all network problems cause bgp route updates, and would be nice to monitor traffic paths to peers for possible correlation of path changes to SIP events.

We'll lose one gateway from a peer for a minute or so, then it'll come right back up. Sometimes the SIP bounce is accompanied with a BGP route flap, sometimes not. It almost always happens late at night, but a few sneak in during the day.
We've got plenty of redundancy to cover the events, so ASR remains high.
Part of our root-cause analysis is seeking an uderstanding of the experiences of similar networks, so I need to ask... Is anyone else seeing a general increase in internet-based peer bounces?
