Congestion control is very important for e!ective and stable operation of ATM (Asynchronous Transfer Mode) networks. Owing to the bursty and unpredictable characteristic of data network tra$c, its congestion control is particularly a challenge for network researchers and designers. The ATM Forum has

In this paper, we investigate the dual control problem\*TCP #ow control at the TCP layer and ABR #ow control at the ATM layer. First, we observe that TCP #ow control and ABR #ow control cannot co-operate well. The worst case is that the slow start after packet loss causes high but unused ACR (Allowe
This paper aims to present a comparative simulation study of the performance of TCP traffic over ATM networks with UBR and ABR services; to identify weaknesses of currently most promising ATM congestion control schemes; and to indicate the requirements for a fairer, simpler and more robust congestio
