Abstract:
Large data centers hosting hundreds of thousands of servers have been built to handle huge amounts of data. In a large data center, servers cooperate with each other, and thus the data center network must accommodate a large amount of traffic between servers. However, the energy consumption of large data center networks is a major problem because several largecapacity switches or many conventional switches are required to handle the traffic. A low-energy hybrid optoelectronic router has been proposed to provide high bandwidth between data center servers. The hybrid optoelectronic router has an optical packet switching functionality and packet buffering in the electronic domain. The optical packet switching provides large bandwidth communication between the optical ports. In addition, the router can be directly connected to server racks by its electronic port. The packets from the server racks are stored in an electronic buffer in the router. Then, the packets are converted into optical packets and sent to another router. Finally, when the packets arrive at the router connected to the destination server rack, they are stored in the buffer, converted to electronic packets, and sent to the destination server rack. In this paper, we discuss a data center network structure that contains hybrid optoelectronic routers. We propose a method for constructing a data center network that uses hybrid optoelectronic routers efficiently. Furthermore, we discuss the effect of the network structure on the number of routers required to accommodate a large amount of traffic in a mega data center.
