| 摘 要： | 针对流媒体直播系统的数据传输,设计了一个应用层组播方案,结合NAT穿透技术构建和维护支持不同种类局域网通信的组播树。该方案的核心内容是提出了一个改进的目的驱动最短路径算法,使用网络传输延迟作为度量值构建低代价最短路径树,可以使从源节点到目的节点的传输延迟最小,并且尽可能减少带宽消耗。组播树维护策略能有效的重构组播拓扑结构,增强组播树的健壮性。

| Abstract: | In order to broadcast stream media data,a solution method of application layer multicast is designed.The solution can construct and maintain a multicast tree to support the communication among different kinds of LAN with NAT-traversal technology.An advanced destination-driven shortest path algorithm,which utilized network latency to build the low-cost shortest path tree,is proposed as the fundamental conception of the solution method.The algorithm can minimize the latency from source to destination and redu... |
