摘　　要：在深入研究区分服务(DiffServ)、多协议标记交换(MPLS)、服务质量路由(QoSR)等技术以及它们之间相互结合的基础之上,提出一个将QoSR与MPLS+DiffServ相融合的下一代IP骨干网络的服务质量模型·详细叙述了该模型的结构以及各组成部件的功能,并给出了边缘路由器节点和核心路由器节点的工作过程,介绍了DiffServ与MPLS的映射方法,最后对该模型进行仿真·仿真结果显示了该模型的负载均衡和故障修复等流量工程的能力·After a discussion on differentiated service (DiffServ), multi-protocol label switching (MPLS) and quality of service routing (QoSR) as well as the integrated approaches among them, a new QoS model of next generation IP network is introduced, which incorporates QoSR in MPLS+DiffServ. The structure of the model and the functions of units in its framework are described individually, and the processes in edge-router and core-router are discussed in detail with the mapping procedure between DiffServ and MPLS stated. Some simulations are carried out for the model, by which the results show the traffic engineering capabilities of the model to balance network load and reroute around fault points.
