A Novel Structure and Route Algorithm for Hybrid DCN Network Based on ExCCC-DCN

With the rapid development of data center network (DCN) technology, researchers have cleverly combined wireless connection and wired DCN to form a new structure, hybrid data center network (HDCN). Exchanged Cube-Connected Cycles (ExCCC) has high scalability and relatively low construction cost and operation energy consumption, which is very suitable for the deployment of large-scale data center. In this paper a novel hybrid ExCCC-DCN structure is proposed by combining the communication characteristics of 60GHz millimeter-wave technology. The transformed hybrid network not only inherits the original structural characteristics of ExCCC-DCN structure, but also effectively reduces the network data traffic and improves the network throughput. We divide the hybrid ExCCC-DCN into several units (pods), and propose a new cluster-based multicast routing algorithm. Comparative experiments prove that the algorithm can effectively reduce the number of multicast links and improve the data throughput during multicast communication when constructing a multicast tree.
