Mega data centers are being built around the world to provide various cloud computing services. As a result, data center networking has recently been a hot research topic in both academia and industry. A fundamental challenge in this research is the design of the data center network that interconnects the massive number of servers, and provides efficient and fault-tolerant routing service to upper-layer applications. In response to this challenge, the research community have begun exploring novel interconnect topologies including Fat-Tree, DCell, and BCube and etc.
