摘要
随着网络流量的增加,光纤网络动态路由计算复杂度随之增加,耗费更多的联合资源.为此,提出光纤网络动态路由联合资源最优分配方法.以有向图形式映射网络节点,计算路由传输频谱利用率.根据带宽、时延、网络延时抖动指标,获取动态路由联合资源.通过传输路径上链路的频谱连续度,选择连续度最佳的频谱业务,基于频谱感知和贪婪算法对业务分割合并,实现联合资源最优分配.实验结果表明,当业务负荷为400 Erlang时,所提方法的带宽阻塞率仅为10％,频谱利用率高达90％.另外,经过一个动态资源的传输周期,该方法的数据节点占比低,说明该方法具有较好的稳定性.
Abstract
With the increase of network traffic,the complexity of dynamic routing calculation in fiber optic net-works increases,consuming more joint resources.Therefore,a joint resource optimal allocation method of Dynamic routing in optical fiber networks is proposed..Map network nodes in the form of a directed graph to calculate the spec-trum utilization of routing transmission.Obtain Dynamic routing joint resources according to bandwidth,delay,and network delay jitter indicators.By selecting the spectrum service with the best continuity through the spectrum continu-ity of the transmission path,the service is segmented and merged based on spectrum sensing and greedy algorithms to achieve optimal joint resource allocation.Experimental results show that when the traffic load is 400 Erlang,the band-width Constrictively of the proposed method is only 10％,and the spectrum utilization rate is as high as 90％.In addi-tion,after a dynamic resource transmission cycle,the proportion of data nodes in this method is low,indicating that this method has good stability.
