Looking for HS protocol analyzers options that can, minimally, filter real time traffic (e.g., ports, applications, sessions/conversations, byte/bit offsets) at rates up to and exceeding OC-3/12 and GigE. Being limited to a few seconds makes troubleshooting or analysis very difficult if not impossible. Our routers are able to keep up with a decent amount of "high touch" and still maintain the pace of traffic flow by employing accelerators (e.g., ASICs). Great.. Now, how do we troubleshoot problems?
