摘要
随着互联网规模的增长,互联网上的用户和应用都在快速的增长,如何提供不同的服务质量(QoS)成为下一代互联网络面临的一个重要问题,而服务质量路由(QoSR)则是其中的核心技术和热点问题。QoSR的主要作用是为QoS业务请求寻找可行路径。本文介绍了QoS技术产生的背景,并在有权图模型和QoS度量的基础上介绍了QoSR的基本概念、研究内容等,最后提出了该领域进一步的研究方向。
With the growth of Internet, the numbers of users and applications in internet are increasing. It is a challenging problem to provide quality of service（QoS） guarantee for the next generation networks, among which QoS Routing （QoSR） is one of the key issues, the main function of QoSR is to find a feasible path for QoS traffic. Firstly the background of QoS technology is introduced in this paper. Based on the weighed graph model and QoS metric, the basic Concept and research content of QoSR are presented. At last, it points out possible further direction in the QoSR field.
