摘　　要：流媒体在互联网应用中占有越来越重要的地位,要实现核心网对各种流媒体业务的有效支持,必须在核心节点处解决流媒体业务对延时、带宽、QoS等方面的性能要求。从流媒体的业务识别、流保序、QoS保证、组播复制几个方面,探讨了核心路由器的流媒体支持方案。Streaming media plays more and more important role in the Internet application, to realize the valid support for streaming media service on backbone network, core routers be able to resolve the performance requirement such as delay, bandwidth, QoS and so on. The solution of supporting streaming media service for core routers is introduced in some aspects, including service identification, flow order-preserving, QoS guarantee and multicast duplication of streaming media.
