Abstract
A multicast rule is represented in a hierarchical linked list with N tiers. Each tier or level in the hierarchical linked list corresponds to a network layer of a network stack that requires replication. Redundant groups in each tier are eliminated such that the groups in each tier are stored exactly once in a replication table. A multicast replication engine traverses the hierarchical linked list and replicates a packet according to each node in the hierarchical linked list.
