Research on Aggregated Multicast Based on Wide-Sense Circuit Tree

To achieve the scalability and Quality of Service (QoS) of multicast service, a Wide-Sense Circuit Tree (WSCT) based on Aggregated Multicast Tree is proposed. By aggregating multicast traffics of the same class, WSCT can efficiently reduce the forwarding states of routing nodes and then improve the multicast scalability. By using Wide-Sense Circuit (WSC) to transfer data packages, MSCT can also improve the package forwarding efficiency and provide QoS.
