Abstract: This paper researches the problem of minimization of delay variation under the multicast end-to-end delay bounded and presents an efficient multicast routing algorithm. By altering the paths from the source node to the destinations, the nodes whose delay are smaller than the average achieves a new delay as big as possible and the nodes whose delay are above the average achieves a new delay as small as possible. Simulation results show that this algorithm can achieve a smaller delay variation.

摘要： 研究多播端到端时延受限条件下的最优时延抖动问题，提出一种有效的多播路由算法。通过修改源节点到目的节点的路径，使时延较小的目的节点获得尽可能大的时延值，时延较大的目的节点获得尽可能小的时延值。仿真结果表明，该算法能获得较小的时延抖动。
