SDN中基于迁移优化的控制器负载均衡策略
Controller load balancing strategy based on migration optimizing in SDN
摘要
Abstract
Aiming at rigid switch migrating and conflicting migration during SDN multi-controller load balancing,this paper optimized the existing switch migration model and proposed a stage controller load balancing strategy (SCLB).In phase one,by synthesizing various types of controller overhead and optimizing the migration target based on genetic algorithm,it selected immigration domain and emigration domain of switch.In phase two,it completed the coordination of multi-switch migration through setting subdomain migration degree and switch validity.The simulation results show that,compared with the existing load balancing policies,SCLB improves the process of selecting migration domain and optimizes dynamic deployment between switch and controller.The controller load balancing level is increased about 21％.关键词
