一类专用网络中的动态路由选择协议

A Dynamic Routing Protocol in a Kind of Special-Purpose Network

在分析现有路由选择协议的基础上,设计了适用于一类专用网络的动态路由选择协议。该协议采用按需路由方式,利用该类专用网络的全连通性缩短初始通信延迟,通过度量链路延迟来确定最佳路由,通过邻接节点信息表的维护实现备份链路的管理,支持到目的节点的多重路由。原型系统实现表明,该协议简单、高效、高可靠和高可用,可以满足专用网络的需要。

Based on the analysis of existing routing protocols, a dynamic routing protocol in a kind of special-purpose network is presented. In the proposed protocol, on-demand routing method is adopted; initial communication delay is shortened by considering full-connected topology; the optimal route is determined bymeasuring link delay; backup links are managed by maintaining neighbor information table. It can also support multi-path routing. Prototype system implementations have shown that the proposed protocol is simple, efficient, reliable and available, satisfying the requirements of a kind of special-purpose network.
