An effective QoS multicast algorithm

In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the internet can be further harnessed in an efficient manner. A QoS-based multicast routing algorithm, considering QoS requirements and network resource constraints is designed and implemented. A heuristic and approximate algorithm, which is based on Dijkstra algorithm and can construct a multicast routing tree that meets the QoS requirements, is presented. Simulation results show that this algorithm is both feasible and effective.
