IP Multicast is an important enabling service for the current and future Internet. With the explosive growth of the Internet, a challenging issue facing IP multicast is scalability, in particular, the problem of multicast forwarding state and control explosion. In this paper, we propose a new methodology to address the multicast scalability problem for backbone domains - Multicast Tunneling with Branch Filtering (MTBF). This multicast group aggregation scheme is designed on top of the inter-domain protocol architecture such as MASC/BGMP, and is independent of any underlying intra-domain multicast protocols. It aggregates multicast groups by constructing Border Router (BR)-based multicast routing trees and forwards data by using an encapsulation technique called Multicast Tunneling (MT). The feasibility and performance of our scheme is demonstrated through analysis and simulations.
