英文摘要：

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.
