随着各种云服务在数据中心网络中的出现，大象流严重导致网络拥塞和负载不平衡。针对这一问题，提出了一种基于软件定义网络（SDN）的大象流负载均衡机制。该机制通过SDN的全局视图获得整个网络的拓扑和状态。然后，它分裂和发送大象流通过多个路径的基础上的比率，这是动态计算，考虑到链路的状态。最后，在OpenFlow实验平台上实现了系统原型。实验结果表明，该机制可以显著提高网络吞吐量和链路利用率，从而提高网络性能。
With various cloud services emerging in data center networks, network congestion and load imbalance are seriously caused by elephant flows. To resolve this problem, a load balancing mechanism based on software defined networking (SDN) for elephant flows is proposed. The mechanism obtains the topology and status of the entire network via global view of SDN. Then it splits and sends elephant flows through multiple paths based on the ratios which are dynamically computed by taking account of the states of links. Finally, the system prototype is implemented in OpenFlow testbed. The results show the proposed mechanism can significantly enhance the performance of the network by improving the network throughput and link utilization.
