VHCN : A Hybrid Data Center Network Based on VLC Link

Abstract

With the development of cloud computing, the importance of data center increases. The traditional data center network is divided into two types. The wired data center network has poor scalability because of the limited number of server ports and equipment costs. Wireless data center network is often regulated by mechanical equipment, resulting in large delays and costs. This paper proposes a hybrid data center network VHCN based on VLC(visible light communication) link, Firstly, compared with the wireless data center network, VHCN does not need external objects and mechanical equipment, and VLC links are plug and play. Secondly, compared with the wired data center network HCN, VHCN does not change the original topology rules of HCN, and VHCN has higher fault tolerance and lower average path length under the same conditions. Finally, this paper proves a unicast and multicast routing algorithm.
