基于SDN的胖树数据中心网络多路径负载均衡算法研究
RESEARCH ON SDN-BASED MULTI-PATH LOAD BALANCING ALGORITHM OF FAT-TREE DATACENTER NETWORK
摘要
Abstract
Software Defined Networking (SDN) is widely used in datacenters and other related fields to achieve centralized control of the network and flexible traffic forwarding by decoupling the control plane from the data plane.To improve the network bandwidth and throughput,datacenter network employ layering network topology structure with multi-path characteristics,such as Fat-tree.However,traditional routing algorithms have limited support for multi-path routing,they cannot make full use of the remaining bandwidth of the network.Therefore,this paper mainly studies the SDN based multi-path load balancing algorithm of Fat-tree datacenter network.By using the centralized control of SDN network,obtain multi-path real-time status information;calculate the available bandwidth of each path,and selects the best forwarding route according to the bandwidth requirement of the data stream.The experimental results show that the proposed algorithm is superior to traditional routing algorithms in not only reducing network propagation delay but improving network throughput,thus it is capable to achieve multi-path load balancing in Fat-tree datacenter networks.关键词
