| 随着云计算的发展，数据中心网络成为近年来学术界和工业界关注的研究热点.现代数据中心网络通常采用胖树等多根树拓扑结构，存在多条可用路径来提供高对分带宽.由于等价多路径路由等传统的负载均衡方法无法适应数据中心网络中高动态和强突发的流量特性，多种针对数据中心的负载均衡方法不断涌现.围绕数据中心中负载均衡的基本问题，介绍了当前国际国内的研究现状，包括基于中央控制器、基于交换机和基于主机的负载均衡方法，并展望了数据中心网络负载均衡的发展趋势. |

| Abstract: |
| With the development of cloud computing, recently data center network has been a hot research topic in both academia and industry. Modern data center network is commonly organized in multi-rooted tree topology, such as fat-tree, with multiple available paths to provide high bisection bandwidth. Since the traditional load balancing scheme such as equal-cost multipath routing is not suitable for highly dynamic and bursty traffic in data center network, many load balancing mechanisms have been proposed. In this study, based on the fundamental research problems of load balancing in data center network, the international and domestic research progress of this area is introduced, including central controller-based, switch-based, and host-based load balancing schemes, and then the research trend of load balancing is prospected in data center network. |
