Nowadays, the research work about data center networking (DCN) mainly focuses on the improvement of the topological properties of DCN. Unfortunately, it has been ignored whether the topologies of DCN are suitable for the cloud computing mechanisms running on DCN. To address this problem, a novel DCN topology for cloud computing was proposed. The effective method of running a mainstream cloud computing mechanism on the new topology was researched. The size and diameter of the new topology was analyzed. Simulation results demonstrate that the new topology is feasible for cloud computing.
