I am in the middle of some experimentation with network traffic simulations. I think it will be better if I describe what I am looking for. I need a IP packet capture utility which can store the entire IP packet. I also want a utility that can playback the stored packets (meaning sending it out on the network) honoring the time intervals. Meaning if there was a gap of 2.5 seconds between two consecutive IP packets, then it should playback the packets with the same gap. I tried checking the ftp.ee.lbl.gov and the Internet traffic archive but could not find a exact match for my requirements. Before I go off writing such a tool, I would like to find out if anyone know of such a tool? I appreciate any help. If anyone is interested in knowing what exactly I am doing, I will be more than glad to fill in the details. Thanks for any help.
