According to the routing traffics in the routing process, we simplify and transform the network topology graph, and gain the effective links with their frequency of use. In the channel allocation process, we group the efficient links and allocate channels to links. 在路由过程根据路由需求,对网络拓扑图进行化简和转化,得到有效链路及其使用频率,在信道分配过程对有效链路进行分组,并进行信道分配。
