Enabling the progressive multicast service deployment

摘要: The IP multicast architecture was not widely deployed because address allocation is difficult and there no scalable solution to inter-domain routing. Hence, an interest in developing protocols that allow the progressive deployment of service by supporting unicast clouds. This paper proposes HBH (hop-by-hop routing protocol). adopts source-specific channel abstraction simplify implements distribution using recursive trees. In this model, data packets have destination addresses. Therefore, supports pure routers transparently. branching-nodes recursively create packet copies implement distribution. constructs a shortest-path tree even presence asymmetric Consequently, provides best routes networks, suitable for eventual implementation QoS-based Additionally reduces bandwidth consumption networks when compared other approaches. results obtained from simulation support our statements.
