【摘要】：针对已有的软件定义网络(SDN)控制器部署关注基于控制消息路由时延最优的问题,引入节点的介数中心性作为参数,分析了介数中心性对于控制器部署位置选择的重要性,并联合节点的可靠性提出了一种基于多参数节点排序方案(MFRS)的控制器位置部署策略,将节点进行排序并分层,依据节点间的连接关系计算出控制权值,最终确定控制器位置.仿真结果表明,MFRS的控制消息路由跳数小于基于时延的最短路径算法,且基于MFRS的网络可靠性高于基于时延的最短路径算法.
[Abstract]:In order to solve the problem of optimal routing delay based on control message, the importance of intermediate centrality to the selection of controller deployment location is analyzed by introducing the centricity of nodes to the existing software-defined network (SDN) controller deployment. Combined with the reliability of nodes, a controller location deployment strategy based on multi-parameter node sorting scheme (MFRS) is proposed. The nodes are sorted and stratified, the control value is calculated according to the connection relationship between nodes, and the controller position is finally determined. Simulation results show that the number of hops of MFRS control message is less than the shortest path algorithm based on delay, and the network reliability based on MFRS is higher than the shortest path algorithm based on delay.
