摘要
介绍QoS模型DiffServ及其实现,通过DiffServ对网络中的通信流量进行分类和策略控制来达到调节网络资源的目的。分析MPLS技术及其实现原理,将灵活的三层IP路由和高速的二层交换技术完美地结合起来;探讨了实现DiffServ与MPLS相结合的DiffServ over MPLS模型,从而实现网络中通信流量的QoS保证。
Introduces QoS model DiffServ and its realization, adjusts the network resources by classifying the traffic flow and controlling the strategy in the network with the help of DiffServ. Analyzed the MPLS technology and its principle of realization, unifies the nimble IP routing of the third layer and the high speed switching of the second layer technology perfectly, Discussed the DiflServ over MPLS model which unifies DiffServ and MPLS, so as to guarantee the QoS of the traffic flow in communication network.
