Abstract :
Measurements on an experimental ATM switch in a local area network have demonstrated significant performance gains for TCP traffic with ATM-level flow control. Without flow control, buffer overruns at the ATM switches feeding into bottlenecks can prevent the TCP from using more than a few percent of the potential bandwidth. A detailed analysis of the cell loss patterns that foil the TCP´s loss recovery strategy is presented. With flow control, the efficiency is nearly perfect. ATM flow control prevents cell loss due to congestion, and as a result the TCP can avoid retransmit time-out delays and maintain a high transmission rate
