摘    要:随着网络多媒体应用技术的发展,局域网和广域网实时传输视频和音频信息正成为非常重要的应用,具有确定服务质量(QoS)保证的网络提供变得日益重要。QoS路由为具有不同QoS要求的应用寻求符合条件的网络传输路径,一般来说,它要能满足用户的QoS请求和优化网络资源利用率两个主要目标。QoS路由是实现网络支持QoS的核心技术之一,也是当前网络技术领域的一个研究热点。文中简述QoS路由的定义,讨论QoS路由的基本概念和问题,并分析尚待解决的若干问题。

关 键 词:网络技术  服务质量  路由  请求应用    可扩展性

Abstract:With the rapid development of Internet multimedia application technology, real time transmission of audio and video information over LANs and WANs is becoming a significant application, which makes it more and more important to ensure deterministic QoS of the networks. QoS routing finds network transmission paths that meet different QoS requirements of the applications. In general, it has two major objectives: one is to meet the QoS requirement for that application, while another is to optimize the utilization of network resources. Since QoS routing is one of the key technologies to implement network-supported QoS, it is becoming a hot spot in this area of research. This paper studies the definition of QoS routing and discusses some basic concepts and problems, then analyses several issues that are to be further studied.
Keywords:network technology  QoS  routing  request  flow  scalability
