基于SDN的数据中心网络负载均衡策略
Load Balancing Strategy for Data Center Networks Based on SDN
摘要
Abstract
Aiming at the problems of current load balancing algorithms in dealing with traffic in data center networks,such as lack of global perspective and dynamic adaptability,dynamic changes of path state,and too complicated calculation,a load balancing strategy is proposed based on the idea of separation of control and forwarding proposed by SDN.The strategy distinguishes between large and small flows.Large flows use the perception ability of SDN to calculate the path set with the fewest hops between the source host and the destination host and the load of the path set.The fuzzy inference algorithm is used to calculate the score of each path,and the flow table is issued to guide the forwarding of data packets on the path with the highest score.Small flows are forwarded according to the forwarding principle of Equal-Cost Multi-Path.The experimental results show that in the Fat-Tree topology,the network throughput and link utilization are improved compared with ECMP and Hedera.关键词
