基于边选择的时延抖动受限组播路由算法

组播技术在多媒体通信的实际应用中十分重要,对各种交互式实时组播业务如视频会议等来说,不仅要考虑时延约束,而且要考虑时延抖动约束。对基于边选择的时延抖动受限的启发式算法进行了研究,仿真结果表明算法复杂度较低,性能也较好。

A Delay Variation Constrained Multicast Routing Algorithm based on Alternative Routing

Multicast routing is more and more important in multimedia applications.Delay and delay variation constraints must be taken into account for interactive real-time application such as video-conferences. We present a new heuristic of multicast routing with delay and delay variation constraints in this paper which is based on alternative routing （AtkMA）. The computer simulations show that the heuristic achieves both low complexity and good performance.
