摘要
随着 Internet技术的迅速发展 ,一系列的服务质量 (Qo S)保证体系逐渐成为人们研究的热点。文章探讨了最新的综合服务、区分服务等一系列 Qo S的体系模型 ,对每种模型的特点进行了分析比较 ,并结合网络数据流的状态对 Qo S的影响 ,提出了一种使网络具有灵活性、可扩展性、鲁棒性和较高服务质量保证的 Qo S模型。该模型综合了集中服务和区分服务 2种体系模型的优点 ,最后给出了该模型实现的算法。
With the rapid development of the Internet,a series of architectures, which guarantee QoS, have been conceived. This paper discusses integrated services, differentiated services and other models, which are new architectures for guaranteeing the QoS. The characteristics of each model are compared and analyzed. Considering the influence of per flow state in networks on the quality of service, this paper puts forward a QoS model which provides a service with flexibility, scalability, robustness and better guarantee level. The model combines the virtue of integrated services and differentiated services. The implementing algorithm of the model is also presented.
