A SURVEY ON HYBRID DATA CENTER NETWORKS

Abstract

Exponential increase in the network traffic demands has led to lot of innovation in the data center networks. The
Hybrid Data Center Network (HDCN) which combines the wired and wireless technologies, have emerged in solving many
problems faced by traditional data center networks. With increasing traffic demands data centers are suffering from
congestion problem. To resolve this issue, Hybrid Data Center Network Architecture was proposed. HDCN support both
wired-IEEE 802.3 and wireless-IEEE 802.11ad transmissions. The HDCN employs high speed 60 GHz wireless technology
to communicate between the switches there by reducing the complexity involved in electrical connection. Further Hybrid
Optical Switches combined with electronic packet switching is used to intelligently manage the on-demand traffic. The data
center is reconstructed to Software Defined Data Center with the technical of Software defined network. The services of data
center are formed into Virtual Data Center, which is based on the virtual resource collection of the physical network section.
Network virtualization techniques have also been considered in realizing the traditional network functions over the virtual
machines.
