本文分析了预约网络中采用多路径路由传送数据以保证应用的带宽要求、和 /或端到端时延限制条件 .文中提出的路由方案综合了单路径和多路径路由的优点 :通过多路径路由以降低呼叫阻塞率 ,同时侧重单路径路由以降低协议开销 .在考察网络中的四个一般性问题基础上 ,提出了启发式算法 . This paper analyzes the multi-path routing in the reservation network to transmit data to ensure the application of the bandwidth requirements, and / or end-to-end delay constraints.The proposed routing scheme combines the advantages of single-path and multi-path routing: Multi-path routing So as to reduce the call blocking rate and focus on single-path routing to reduce the protocol overhead.On the basis of investigating four general problems in the network, a heuristic algorithm is proposed.
