| 摘 要： | 提出了一种基于邻近原则的用于视频流直播服务的应用层多播协议.协议通过使用每个节点预生成的网络坐标信息,按照邻近原则调度的方法,构建一棵低延迟、低连接压力的层次化单源多播树,同时协议解决了真实网络中的部分服务能力限制问题,扩大了系统的可扩展性和可用性.

| Abstract: | This paper proposes a multicast protocol at the application level for efficiently broadcasting live media streams to a large number of users.The main idea of this protocol is to self-organize the end hosts into a locality-aware overlay multicast tree based on their network position coordinates.The result is that the overlay multicast tree has a good match to the underlying physical network such that the link stress and the end-to-end delay can be effectively reduced.In the mean time,real-life network constraints can be handled. |

| Keywords: | stream media multicast tree locality-aware network position coordinate |
