【摘要】:針對已有的軟件定義網(wǎng)絡(luò)(SDN)控制器部署關(guān)注基于控制消息路由時延最優(yōu)的問題,引入節(jié)點的介數(shù)中心性作為參數(shù),分析了介數(shù)中心性對于控制器部署位置選擇的重要性,并聯(lián)合節(jié)點的可靠性提出了一種基于多參數(shù)節(jié)點排序方案(MFRS)的控制器位置部署策略,將節(jié)點進行排序并分層,依據(jù)節(jié)點間的連接關(guān)系計算出控制權(quán)值,最終確定控制器位置.仿真結(jié)果表明,MFRS的控制消息路由跳數(shù)小于基于時延的最短路徑算法,且基于MFRS的網(wǎng)絡(luò)可靠性高于基于時延的最短路徑算法.
[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.
