Multicast business has been widely applied in all kinds of streaming media.These business need more QoS requirement.In order to solve the QoS problem,the multiple constraints multicast routing has become a very important research field.The multiple constraints include bandwidth and delay.In this algorithm,first,all the links are traversed and those links do not meet the bandwidth requirements are eliminated.Then,the algorithm selects the links meet the minimum delay from the source node to the destination node to component the final path in the rest links.Through designing one network topology including six nodes,using a network simulation tool to gather statistics of each link utilization,the result verifies the validity and simplicity of the algorithm.
