Abstract:
1. A method comprising: receiving a multicast packet at an ingress system of a packet-forwarding engine (PFE); identifying, by the ingress system, a plurality of flow classification indices for the multicast packet; sending, by the ingress system, the plurality of flow classification indices to an egress system of the PFE; buffering a single copy of the multicast packet in a memory accessible by the egress system; identifying, by the egress system, corresponding transform control instructions based on each flow classification index of the plurality of flow classification indices; reading the single copy of the multicast packet from the memory; transforming the multicast packet to an outgoing packet for each instance of the multicast packet based on the corresponding transform control instructions; and transmitting the outgoing packet for routing to a network.
