چکیده
We extend our earlier studies of buuer requirements of TCP over ABR 10, 11, 12] in two directions. First, we study the performance of TCP over ABR in an ATM backbone. On the backbone, the TCP queues are at the edge router and not inside the ATM network. The router requires buuer equal to the sum of the receiver window sizes of the participating TCP connections. Second, we introduce various patterns of VBR background traac. The VBR background introduces variance in the ABR capacity and the TCP traac introduces variance in the ABR demand. Some simple switch schemes are unable to keep up with the combined eeect of highly varying demands and highly varying ABR capacity. We present our experiences with reening the ERICA+ switch scheme to handle these conditions.

متن کاملPerformance and Bu ering Requirements of Internet Protocols over ATM ABR and UBR Services
The Asynchronous Transfer Mode (ATM) networks are quickly being adopted as backbones over various parts of the Internet. This paper analyzes the performance of TCP/IP protocols over ATM network's Available Bit Rate (ABR) and Unspeciied Bit Rate (UBR) services. It is shown that ABR pushes congestion to the edges of the ATM network while UBR leaves it inside the ATM portion.
