摘要
介绍了两种主要的服务质量机制——综合服务模型与区分服务模型,针对两者的不足,提出一种将服务质量进行分层处理的改进方法,即层次化的服务质量部署方案.该方案已经应用到河南大学校园网络二期工程中,运行效果表明了其实用性和可行性.
Firstly, this paper analyzed two most important kinds of architectures for QoS, Integrated Services model and Differentiated Services model. After discussing the deficiency of Intserv and Diffserv, this paper brought forward a new QoS method, namely, Hierarchical Quality of Service. Finally is a detailed analysis of H-QoS model. Currently, the solution based on H-QoS has applied to HNUCN-2E （the Second Engineering of HeNan University Campus Network）. The result of performance demonstrated it＇s availability and feasibility.
