Abstract
IP multicast originally works in Any Source Multicast (ASM) that comes with great burden and dynamics on the backbone routers and weakness in inter-domain scalability. It also brought serious security and management problems. In contrast, Source-Specific Multicast (SSM) has been recognized as a simple, scalable and secure method, especially in inter-domain multicast. However, its applicability to many-to-many applications and other issues lead to stagnation in deployment. In this paper, a novel ASM-over-SSM (AoS) architecture is proposed as a solution for scalable inter-domain multicast. Evaluations demonstrate that AoS mitigates the dynamics and complexity in core routers, and reduces states in inter-domain multicast, without modification on current routing infrastructure and multicast applications.
