Data centers play an important role with the fast growth of cloud computing used in our daily life. Traditional data center networks based on the fat-tree topology have their own drawbacks and limitations which prevent them from providing high performance to satisfy the increasing demand for cloud services. In this paper, we first design a new flexible network fabric for data center networks based on the concept of Software Defined Networks (SDN). Then, we also propose a simple yet efficient route calculation algorithm for this architecture. Simulation results show that the improved SDN-based switch fabric topology can support more hosts, provide more bandwidth and the shortest paths are found in a smaller amount of time.
