摘要
阐述了 ＩＰ网络具有 ＱｏＳ（Ｑｕａｌｉｔｙ ｏｆ Ｓｅｒｖｉｃｅ）保证的必要性，分析了 ＩＥＴＦ提出的综合业务结构模型（Ｉｎｔ＿Ｓｅｒｖ）与分类业务结构模型（Ｄｉｆｆ＿Ｓｅｒｖ）的异同和适用环境以及解决拥塞控制的具体方法，给出了实现 ＩＰ网络 ＱｏＳ的解决方案 ＭＰＬＳ＋Ｄｉｆｆ＿Ｓｅｒｖ．
The necessity of guaranteeing QoS (quality of service) by the IP network is expounded. Then the similarities, differences, and application situation of both configuration models of integrated service (Int_Serv) and differentiated service (Diff_Serv) presented by IETF as well as the concrete measure of dealing with jam control are analysed. Finally, a disposition scheme of realizing the QoS in IP network, viz MPLS+Diff_Serv is given.
