Architecting Network Structure for Data Center: A Scalable Hierarchical Approach

This paper presents a server centric approach for architecting data center network(DCN) by using a hierarchical model. Considering that the network infrastructure must be scalable to a large number of servers and allow for incremental expansion, we design a high scalable DCN with high performance. The results imply that our approach is more feasible, and possess the good regularity and expandability that help reduce the cost of further expansions.
