摘　　要：针对网络链路的可靠性在网络设计中的重要性,提高网络中所选路径的可靠性、提升业务性能,提出了一种基于网络可靠性指标的路由算法(BRI)。该算法综合考虑了链路的可靠性、带宽等方面的因素,对网络链路的可靠性进行了深入的研究,找出了能提升业务性能、提高可靠性的路由。建立了网络拓扑结构的数学模型,描述了具体的路由算法,最后给出了数值仿真实例。仿真结果表明,算法在提高所选路径的可靠性、提升业务性能、有效利用网络资源等方面是可行的和有效的。As link reliability is very important in network designing, a QoS routing algorithm based on network reliability index is presented to improve network reliability of the chosen path and business performance. The algorithm conducted a depth study about the reliability of the network, taking link reliability and bandwidth into account. A mathematic model for network topological is constructed and the routing algorithm is introduced in detail. The simulation shows that the algorithm is feasible and effective in improving the reliability of the chosen path, enhancing business performance, using network resource efficiently.
