摘要 保证服务质量的QoS路由 (QualityofServiceRouting)是网络中解决QoS问题的一项关键技术 .QoS路由的主要目标是为接入的业务选择满足服务质量要求的传输路径 ,同时保证整个网络资源的有效利用 .度量参数选择问题、寻路问题和路由信息不准确问题是QoS路由中的几个主要研究内容 .本文围绕这三个方面 ,介绍了QoS路由中的主要问题及相关的解决办法 ,并探讨了今后QoS路由可能的研究方向 . QoS Routing is one of the key technologies to provide quality of service in future networks.The goals of QoS Routing are to select feasible paths that meet QoS constraints and to make efficient utilization of the network resource.Metrics selection,feasible paths search and node state information accuracy are three key issues in QoS Routing.On these three issues,this paper presents problems and solutions in QoS Routing,and discusses the possible future directions in the QoS routing area.
