Thanks, John and Bob,

Bob, I've installed Netmon and I am struggling (though winning, I think) with getting it to work the way I'd like it to work. Capturing isn't the problem - it's displaying the right stuff while discarding/disregarding the minutiae.

John, I will try WireShark presently.

What I'd really like to have is an accumulating histogram of the packet traffic that comes and goes between each of the nodes on my LAN and the Internet. I don't care about all the other traffic that's going on between my LAN nodes. (Someone(s) in my house is using most of the bandwidth (!!) and I'm going to find out who -- heh! heh! We're still waiting for FIOS in our neighborhood.)
