This paper proposes DINloop (Data-In-Network loop) based multicast with GMPLS (generalizedmultiprotocol label switching) to overcome the scalability problems existing in current inter-domain multicast protocols. In our approach, multiple multicast sessions share a single DINloop instead of constructing individual multicast trees. DINloop is a special path formed using GMPLS to establish LSPs (Label Switched Paths) between DIN Nodes, which are core routers that connect to each intra-domain. We adopt link bundling method to use fewer labels. Packet Processing Module analyzes the coming multicast message and GMPLS Manager assigns a label to it. Then the multicast packet is fast forwarded using label. Simulations show that DINloop-based multicast uses the smallest message number needed to form the multicast structure compared with conventional inter-domain multicast protocols. In addition, the routing table size in core routers does not increase as the number of multicast group increases, and therefore the routing scalability is achieved.
