Multi-source Application Level Multicast System Based on Real-time Stream Media Service

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%.
