基于软件定义网络的WLAN架构及负载均衡切换
Wireless LAN and load balance strategy based on software defined network structure
摘要
Abstract
Software-defined network separates control plane and data forwarding plane,providing open programming inter-faces,which greatly increases the flexibility of network management.In traditional wireless LAN,terminals usually select the access point based on signal strength,and this mechanism often causes low resource utilization and access point load imbalance.In order to solve these problems,this paper proposes a wireless LAN architecture and a load balance handover strategy based on software defined network.The main idea is to use the SDN controller’s global view of network and the ca-pability of centralized management,monitor and analysis of the status of each access point in the network,compute their weight,and manage them based on load.Hardware and computer simulation platform experimental results show that,com-pared with traditional wireless LAN,the scheme effectively improves the utilization of network resources,balances the load between access point,reduces the data transmission delay during the terminal handover process and improves the perform-ance of network.关键词
