In ATM networks, congestion usually results in cell loss. In this paper, an arbiter method for congestion control is proposed. Based on the time limit and priority, the cells that compete for the same output line could be lined according to the character of real-time services. We define /spl Pi//sub ij/ as the transmission probability of a cell to be transmitted from the input line i to the output line j. So each cell can be described clearly and the congestion control arbiters (include internal arbiter and external arbiter) could classify the cells that in competition. Experiments show that this method is effective in improving cell loss rate.
