摘要

在规划供公众访问的回程网状网络结构时,通常会在网状网络中引入冗余节点。这些被称为冗余,因为在正常运行下,由于路由协议的最短路径度量,它们不会增加网络容量。相反,它们的唯一目的是通过在最短路径中的链路发生故障时提供故障转移链接来提高网络可靠性。本文展示了如何估计引入冗余节点所带来的额外网络可靠性。还可以找到冗余节点的最佳位置,即在何处放置节点以最大限度地提高额外的网络可靠性。

The reliability and availability of wireless backhaul mesh networks
When planning the structure of a backhaul mesh network for public access, it is common to introduce redundant nodes in the mesh network. These are called redundant, because they do not increase the network capacity under normal operation, due to the shortest-path metric of the routing protocol. Instead, their sole purpose is to increase the network reliability by providing failover links when a link in the shortest-path fails. This paper shows how to estimate the additional network reliability that results from introducing a redundant node. The best location of a redundant node, i.e. where to locate the node in order to maximise the additional network reliability, can also be found.
