Abstract
Approaches for multicast routing a group packet that includes a payload and routing information (e.g., a target identifier vector and a target multicast group ID) in a network having multiple cells each comprising a parent node and one or more child nodes include establishing and storing one or more child-node multicast group map tables associated with the child node(s) for each cell; receiving a multicast group packet; determining whether to forward the multicast group packet to the child node(s) based at least in part on the child-node multicast group map table(s) associated therewith and the received target identifier vector; and if so, causing the parent node to forward the multicast group packet to the child node(s).
