摘　　要：提出了一种新的基于MPLS的Diff-serv模型——扩展LSP模型，它较好地解决了可扩展性、支持所有PHB和支持多种数据链路层媒体这3个基于MPLS的骨干网IP QoS实现方案面临的关键问题，并且通过将扩展LSP模型与现有的3个模型进行分析比较，表明扩展LSP模型是一种基于MPLS的功能完善且可行的IP QoS模型。This paper presents a new MPLS-based Diff-serv model which could satisfyingly resolve three key problems faced by the IP QoS realization of MPLS-based backbone network: scalability, ability to support all PHB and ability to support various data link layer media. After the analysis, comparison and contrast between expended LSP model and other three MPLS-based Diff-serv models, this paper proves that this new model is a well functional and feasible MPLS-based IP QoS model.
