一种基于三层结构模型的SDN负载均衡方案
A LOAD BALANCING SCHEME OF SDN BASED ON THREE-TIER ARCHITECTURE
摘要
Abstract
The static mapping relationship between the switch and the controller causes the load of SDN control plane to be unbalanced.To solve this problem, this paper proposes a load balancing scheme SMLB based on three-tier architecture.SMLB uses the controller management layer, the controller cluster, the data layer pattern.To balance the control plane load, SMLB changes the static mapping between the switch and the controller of migrating switch based on three-tier structure model.Simultaneously, SMLB overall considers the load factor and the distance factor in selecting migration switch to be migrated and idle controller.The experimental results show that SMLB can effectively control the plane load and reduce the network delay, so as to improve the control plane scalability.关键词
