Abstract
ATM networks are quickly being adopted as backbones over various parts of the Internet. This article studies the dynamics and performance of the TCP/IP protocol over the ABR and UBR services of ATM networks, sp ecifically the buffering requirements in the ATM switches as well as t he ATM edge devices. It is shown that with a good switch algorithm. AB R pushes congestion to the edges of the ATM network while UBR leaves i t inside the ATM portion. As a result, the switch ABR buffer requireme nt for zero-packet-loss high-throughput TCP transmission is a sublinea r function of the number of TCP connections.
