摘　　要：由于网络电视(IPTV)、3G业务的开展,网络业务呈现多样化,对业务的可靠承载传送和带宽的高效利用提出了更高的要求,需要通过技术手段加以解决。利用多业务传送节点(M STP)内嵌弹性分组环(RPR)技术所具有的业务分类传送、快速保护倒换、公平接入机制及高效带宽利用的特点,在城域网组网中实现了快速提供大客户专线业务、IPTV业务的有保障传送和3G接入传输网建设的最优化等应用。该技术已被中兴通讯在城域网组网中进行商用。M STP内嵌RPR技术适合当前IPTV、3G建网应用,可实现不同类型业务综合应用的高效可靠传送。Along with the deployment of tPTV and 3G services, the diversification of network services imposes higher demands on the reliable bearing and transmission of services and the effective utilization of bandwidth. This problem can be solved by relevant technical means. With the features of packet service transmission, fast protection switching, fair access mechanism, and highly effective bandwidth utilization, the MSTP-embedded Resilient Packet Ring （RPR） technology, while used in MAN networking, enables such applications as the quick launch of private services for group users, the guaranteed transmission of IPTV services and the optimization of transmission networks for 3G access. This technology has been commercially used in MAN networking by ZTE. It is proved that the MSTP-embedded RPR technology can be effectively used for the construction of IPTV and 3G networks and the reliable transmission of diversified integrated services.
