摘要: 针对软件定义网络(SDN)多域网络中存在子域规划及控制器部署不合理的问题,提出一种新的SDN多域自适应管理方法。基于改进的节点聚类思想,设计SDN子域划分优化算法,依据网络中的吸引度和归属度对节点进行聚类,完成子域规划。面向子域中不同网络代价,给出控制器自适应部署算法,并通过代价加权求和得到子域网络总开销,完成控制器部署。仿真结果表明,与控制器自适应部署算法、负载均衡算法等相比,该方法网络子域划分和控制器部署更加合理,可节约23%的备份控制器空间,改善网络的综合性能。

Abstract: Aiming at the problem that sub-domain planning and controller deployment are unreasonable in Software Defined Networking(SDN) multi-domain networks,a new SDN multi-domain adaptive management method is proposed.Based on the improved node clustering idea,the SDN Sub-domain Dividing Optimization Algorithm(DDOA) is designed.The nodes in the network are clustered according to the degree of attraction and attribution,and the sub-domain planning is completed.For the different network costs in the sub-domain,the Controller Adaptive Deployment Algorithm(CADA) is given,and the cost of the sub-domain network is obtained by cost-weighted summation to complete the controller deployment.Simulation results show that compared with the controller adaptive deployment algorithm and load balancing algorithm,the network sub-domain division and controller deployment are more reasonable,which can save 23% backup controller space and improve the overall performance of the network.

Key words: Software-Defined Networking(SDN), sub-domain planning, node clustering, controller deployment, adaptive management
