Abstract: Quality of service (QoS) based routing and scalability are two key features of multicast routing for next generation internetworks. The paper proposes a new protocol called QoS-aware hierarchical multicast routing protocol (QHMRP) that achieves scalability by organizing the network as a hierarchy of domains using the full-mesh aggregation technique. The protocol uses a novel reverse flooding approach with hierarchical, topological and QoS forwarding conditions to construct the multicast tree while minimizing message overhead and satisfying QoS ...
