I've got a huge pcap file (many GBs) that I just can't load in wireshark. What I need is extracting bandwidth usage information, both total and per-protocol (in both incoming and outgoing direction), from it, and possibly graph it in a manager-friendly way.
Essentially, I need something that can process pcap files on the command line, and outputs usage statistics in a format suitable for visualization or usage with tools like rrdtool et al. Any advice welcome.
