摘　　要：在IP网络中,业务数据报文从源节点到目的节点的最优路径由单播路由协议计算得出,当网络中存在多条传播路径时,一般是由链路状态路由协议计算得出次优路径。研究一种协议无关的、与业务主路径不重合的次优传输路径生成方法,采用源路由方式引导业务报文按照生成的次优路径从源节点传输到目的节点。该方法在次优路径生成过程中无需获取全网拓扑,并且不占用主路径的链路带宽。The data packets flow from the source to the destination will propagate along the optimal path calculated by the unicast routing protocol.If there are other paths from the source to the destination,it needs to be calculated by the link state routing protocol.A protocol independent method is provided to find the sub optimal path that does not coincide with the current service path,and it enables the source computer to guide the flow according to the strict source routing through this path.This method does not need to obtain the whole network topology,and the path search process does not occupy the bandwidth of the current optimal path.
