  • Arbitration mechanism for a multicast logic engine of a switching fabric circuit
    Patent number: 5898687
    Abstract: A multicast engine of a shared-memory switching fabric circuit increases the replication rate of data elements destined for multicast connections within a network switch by manipulating address information relating to those elements. The multicast engine cooperates with other components of the switching fabric circuit to minimize the total buffer requirements of the switch by storing only a single copy of each multicast data element in a location of shared memory. Specifically, the engine has a pipelined architecture that provides a multicasting capability for the switching fabric circuit by replicating only an address pointer to that memory location for each destination of the multicast connection.
