FEEDBACK RESTRICTED ACCESS QUEUES FOR CONTROLLING CELL LOSS IN ATM NETWORKS

A system is proposed whereby at the switching nodes in an ATM network, the probability of cell loss due to buffer queue overflow is not cons tant for each virtual channel but can be controlled in accordance with the rate of cell generation. There is evidence to show that for video services, such a system would improve the quality of service for the majority of users. The system has the advantage that the control would be applied at intermediate nodes in the network without the necessity for additional signalling between nodes.
