In this paper, we investigate the dual control problem - TCP flow control at the TCP layer and ABR flow control at the ATM layer. First, we observe that TCP flow control and ABR flow control cannot co-operate well. The worst case is that the slow start after packet loss causes high but unused ACR (Allowed Cell Rate) which raises the potential of cell loss and an underflowed switch queue which reduces ABR throughput. We suggest to implement a use-it-or-lose-it policy for ABR and fast recovery for TCP to avoid these phenomena.
