Bill, Usually the Internet core routers try to keep IP packets reletivly have the same size or without Option's field in order switch packets in the hardware roueter backplane. Ther are many studies will be reflected one way or another on the IP packet size. One of them might be found on the URL http://diffserv.Ics.mit.edu. Regards, Ehab H. Hadi Nortel, LTD.

TO: nanog@merit.edu Sender: owner-nanog@merit.edu

Anyone know of any studies documenting this? A know that IP packets over the Internet tend to be smaller rather than larger, but I wondered if anyone has published something.
