摘　　要：矿区流媒体传输存在距离远、位置分散和网络异构性等特点,而且现场监控网络质量差和干扰因素多,导致矿井流媒体传输存在带宽瓶颈。在矿区现有高速主干网络中布置流媒体服务器,构建矿区的应用层组播系统。减少了传输的数据冗余,节省了网络传输带宽,避免因占用带宽过多冲击现场低速网络和安全监测系统。The stream media transmission in the mining area is characterized by long distance,scattering terminals and heterogeneousity of networks.In addition that low quality and multiple interferences of the monitoring networks on-site make the bandwidth bottleneck in it.An application level multicast system is proposed by disposing steam media servers in existing high-speed main network of the mining area.It is able to reduce redundant data in transmission,and avoid attacks to low-speed network and safety monitoring system from overcrowded bandwidth.
