Abstract(in English) | In recent years, due to the increase of Internet services and the spread of smartphones, the number and scale of data centers are increasing. With the growth of the traffic amount between data centers, increase in power consumption has become a major problem. The Optical communication technology achieves lower power consumption than the electrical communication and is attracting attention as a method of configuring a energy-efficient data center network. An architecture that introduces an optical circuit that directly connects Top-of-Rack switches and realizes optical circuit switching communication in a data center network is being studied. However, since switching speed of a MEMS (Micro Electro Mechanical Systems) utilized for the optical switch is slow, this conventional architecture cannot deal with the flow group that requests change of optical path route frequently. In this paper, to target the data center architecture using the directly-connected optical circuit, we proposed a data center architecture that introduces PLZT (Plomb Lanthanum Zirconate Titanate) optical switches that change the optical path route in nanoseconds. In addition, to realize the optical circuit switching communication that uses PLZT optical switches, bandwidth allocation using TDM (Time Division Multiplexing) is proposed. Simulation results show that the proposed architecture achieves higher utilization of optical circuit and 45% reduction in maximum power consumption ratio as compared with the Helios conventional techniques. |
