In this paper we propose a novel algorithm for the implementation of best effort services in ATM LANs. The algorithm is a peculiar version of ABR in which sources can transmit only at two different cell rates, the Peak Cell Rate (PCR) and Minimum Cell Rate (MCR); for this reason, the proposed algorithm is called Stop Si Go ABR. The Stop & Go ABR algorithm is first described, and then evaluated by detailed simulation of a simple ATM LAN configuration with best effort TCP connections as well as interfering VBR connections, showing that it is capable of providing very good performance and fairness.
