摘　　要：软件定义网络(Software Defined Network,SDN)的服务器负载平衡与传统的负载平衡方法相比,能有效提高服务器负载平衡的性能,降低实现的复杂性。基于SDN网络架构改进的Dijkstra多路径路由算法,当数据流到达网络设备时,能有效地计算出多条可选路由路径,将数据流按比例分配到各路径,从而实现SDN网络环境下的多路径负载均衡。该算法有效降低了网络中单一路径的负载,实现了基于SDN网络环境下多路径路由的负载均衡。Compared with traditional load balancing methods,SDN(Software Defined Network)based server load balancing can effectively improve the performance of server load balancing and reduce the complexity of implementation.The proposed Dijkstra multi-path routing algorithm,based on SDN network architecture,can effectively calculate multiple optional routing paths,and allocate data flows to each path in proportion,so as to achieve multi-path load balancing in SDN network environment,when data flows arrive at network devices.This algorithm effectively reduces the load of a single path in the network,and realizes the load balancing of multipath routing based on SDN network environment.
