基于安全度的QoS选播路由算法

QoS Anycast Routing Algorithm Based on Safety Probability

提出一种基于安全度的QoS选播路由算法。该算法从负载平衡的思想出发,利用非精确网络状态信息,赋予每条链路一个与全局资源相关的权值即链路安全度,寻找链路安全度较高的选播路径。实验结果表明,该算法能有效平衡网络负载和服务器负载,提高了源节点的请求接受率。

It is proposed a new QoS anycast routing algorithm based on safety probability, in which each link is given a weight related to the global resources by considering the load balance and inaccurate information of networks. The weight is the safety probability of links, so we can find out an anycast route with the relatively bigger safety probability. Experiment results show that the algorithm can balance the load of networks and servers, and can increase the accepting rate of request efficiently.
