摘　　要：提出一种软件定义数据中心网络方案.采用多控制器进行层次多域管控,引入向量地址作为数据交换标签,结合自主研发低造价交换设备和商业级服务器设计,并实现数据中心网络模型.实验结果表明,该方案具有良好的实用性和可编程特性,有效地解决了数据中心网络扩展性差、运维成本高和管控方式复杂等问题,为构建未来绿色节能数据中心网络提供了重要思路.With employing vector address as the switching label, a new type of data center network de- ployment scheme named software defined data center network was proposed. The restriction of the pro- cessing ability of controllers and the bandwidth for control channel was solved in the scheme by adopting hierarchical multiple controllers. A self-developed OpenFlow switch was applied combing with commercial servers in constructing the new data center network. It is shown that the scheme has good practicability and programmable features, and it effectively solves the problems such as poor scalability, high mainte- nance cost and complex management in data center network. The scheme also provides a valuable refer- ence for the construction of green data center network.
