Title: MULTIPOINT TO MULTIPOINT TREES FOR COMPUTED SPRING MULTICAST
Abstract:
A method and apparatus is executed by a network device in a source packet in routing (SPRING) network. The method is to establish a multipoint to multipoint multicast distribution tree where the network device is selected as a rendezvous point for the multipoint to multipoint multicast distribution tree. The method includes advertising the rendezvous point with a multicast group identifier and multicast segment identifier via a control plane protocol, receiving at least one interest registration from receivers of the multicast group via the control plane protocol, and constructing the multipoint to multipoint multicast distribution tree with the rendezvous point as a root and each of the receivers as leaves using unicast tunnels and replication points.
