摘要
随着Internet网络的不断发展 ,它将成为未来网络服务的平台 ,而未来网络服务的种类又是多种多样的 ,既有传统的尽量服务 (Best EffortService)应用 ,又有对网络服务质量[1] (QoS :QualityofService)有着特殊需求的应用 .本文探讨了如何在网络层路由这一层面进行QoS组播路由支持的问题 .目前 ,已有许多组播QoS路由算法提出 ,在QoS路由性能、网络资源使用效率以及路由吞吐率等方面取得了许多好的成果 .针对这些QoS路由算法中存在的一些问题 ,提出了一种组播QoS路由算法 .实验结果表明 :该算法在适应网络拓扑结构、网络规模、对称 /非对称链路负载等方面 ,与其它QoS路由算法相比 。
With the rapid growth and development of Internet,it will become the ultimate platform which provides all kinds of network services.Among these network services based on the Internet platform,there are not only best-effort services,but also quality-guaranteed services [1].In this article,we discuss the issues on how to support quality services of multicast communications on the network layer by way of QoS(Quality of Service) routing strategy.Currently,there have been many multicast QoS routing algorithms proposed in literature.All these algorithms achieved lots of exciting results in network resource utilization and throughput,but still have some problems to be improved.Based on these problems,we proposed our QoS routing algorithm,and the experiment shows that compared to the other proposed algorithms,our algorithm has many improvements on adaption to network topology,network size,symmetric and asymmetric link load.
