Scalable QoS Multicast Provisioning in Diff-Serv-Supported MPLS Networks
Overview IP multicast suffers from scalability problems as the number of concurrent active multicast groups increases, since it requires a router to keep a forwarding state for every multicast tree passing through it. In QoS multicast provisioning, the problem is exacerbated, since not only the forwarding state but also the resource requirement of a multicast group must be kept at the router. To provide scalable QoS multicast support, this paper proposes a novel architecture, called Aggregated QoS Multicast (AQoSM). Using the concept of aggregated multicast, AQoSM can support QoS multicast scalably and efficiently in Diff-Serv-Supported MPLS networks. This paper develops the framework for the architecture and provides a feasibility check from an implementation point of view.
