A switch guaranteeing a minimum amount of memory space for desired connection while allowing efficient dynamic change of maximum memory space that can be used by a connection. Only an amount of memory space which is required for guaranteeing the minimum amount of memory space is reserved. When the reserved space is decremented due to new cells being received on connections, the maximum memory space reserved for each connection is dynamically increased. For multicast connections, only a single copy of the cell data is stored even though a multicast cell is transmitted on several ports. Multicast cells can also be processed using the same signals used for processing unicast cells.

Efficient method and apparatus for allocating memory space used for buffering cells received on several connections in an asynchronous transfer mode (ATM) switch
