AN ADDRESS-BASED QUEUE MECHANISM FOR SHARED BUFFER ATM SWITCHES WITH MULTICAST FUNCTION

The address-based queues are widely used in shared buffer ATM switches to guarantee the order of the cell delivery. In this paper, we propos e an address-based queue mechanism to achieve an efficient use of the shared memory under a multicast service. In the switch. both cells and the address queues share the common memory. Each queue length changes flexibly according to the number of the stored cells. Our approach si gnificantly reduces the cell lass probability as compared with the pre viously proposed approaches.
