METHOD AND APPARATUS FOR BYPASS ROUTING OF MULTICAST DATA PACKETS AND AVOIDING REPLICATION TO REDUCE OVERALL SWITCH LATENCY

摘要

An apparatus for routing multicast data packets, the apparatus includes an ingress port to receive data streams of multicast data packets and status data about egress ports available to transmit the multicast traffic data streams. A processor coupled to the ingress port, to identify source data of the multicast data packets of the data streams to match the multicast data packets with available egress ports. The processor to determine, using the identified source and status data which of the multicast data packets matches the available egress ports. The processor to select a first data path coupled to the egress port to transmit the matched multicast data packets to available egress ports where the selected first data path is configured to enable the direct transmission of the matched multicast data packets to available egress ports.

1. A method of routing multicast data packets, said method comprising:
receiving, at an ingress port, data streams of multicast data packets and status data corresponding to egress ports available to transmit the multicast data streams; identifying, by a processor coupled to the ingress port, source data of multicast data packets of data streams to match multicast data packets with available egress ports; determining, by the processor, using the identified source and status data which multicast data packets match available egress ports; and selecting, by the processor, a first data path coupled to the egress port to transmit matched multicast data packets to available egress ports wherein the selected first data path is configured to enable direct transmission of matched multicast data packets to available egress ports.
