Using Available Bit Rate (ABR) service of Asynchronous Transfer Mode (ATM) at a backbone link will provide a lossless network. It, however, causes congestion at an edge-router and is reported to show poor end-to-end TCP performance. We consider how to improve the performance of TCP over a backbone ABR network. By using ABR feedback information (ACR) at edge-routers, we can adjust intervals of TCP Acknowledgement packets. This adjustment couples the ABR rate-based control loop and the TCP window-based control loop. Based on this scheme, we can achieve a good end-to-end TCP performance as well as good ATM layer performance over backbone ABR. This paper describes comprehensive study on the proposed mechanism.
