commercially, we're really fond of 'packeteer'. we use its traffic shaping
a lot on our campus network, to great effect.
freeware based, and hence it may get overloaded and crash, i like 'iptraf'
a lot. it can measure protocols and ports, does so pretty well on a
decently size LAN (ie 10/100) using a typical OpenBSD desktop.
hope this helps. i'm sure other people will chime in with better
suggestions.
