| 摘 要： | 针对矿区网络大容量视频信号传输，通过在现有网路中部署流媒体服务节点，构建基于实时流媒体服务的多源应用层组播系统，并提出一种基于度和延时约束的路由算法，进行组播树节点的管理和优化。该系统实现简单、路由健壮性高，与传统C/S模式视频监控系统相比，在同等网络状况和运行环境下，传输视频流的网络丢包率降低50%以上。

| Abstract: | In order to transmit real-time video in mining Intranet reliably, a multi-source application level multicast system is proposed by deploying stream service nodes in current network. A delay-bounded and degree-bounded routing algorithm is used to manage and optimize the nodes in the multicast tree. The validity of the system is verified by practical performances. Compared to the average frame loss rates of the traditional C/S video-monitoring system, those of the proposed multicast system decreases above 50%. |
