一种改进的端到端混合QoS模型

An Improved End-to-End Mix QoS Architecture

简要分析了几种QoS(服务质量)模型的优缺点,在此基础上将Intserv/RSVP、Diffserv和MPLS结合起来,建立了一种改进的端到端混合QoS模型,并给出了其具体实现方法,重点探讨了核心网络实现中的若干问题和各种服务类型之间的映射问题.该模型具有区分服务的良好扩展性和鲁棒性,实现了端到端的QoS保证.

On the basis of analyzing briefly the advantages and disadvantages of Several QoS architectures,this paper combines Intserv/RSVP,Diffserv and MPLS with each other.Then,an improved end-to-end mix QoS architecture is established and its concrete implementation of Differentiated Services is provided,it mainly studies some problems in the implementation of the core nework and various types of service mapping.The proposed arthitecture possesses good expansibilities and robustnesses in Differentiated Services meanwhile providing end-to-end QoS guarantee.
