Data Center Network Topologies Using Optical Packet Switches

The large data center network constructed of only the electronic packet switches consumes large power to provide enough bandwidth for all server pairs. One approach to construct the data center network that provides enough bandwidth with small energy consumption is to use the optical packet switches. In the data center network using the optical packet switches, however, the failures of the optical packet switches may have large impacts on the communication between servers. In this paper, we propose the data center network topology using the optical packet switches that can provide enough bandwidth even when some optical packet switches fail. We evaluate our topology and clarify that our topology can provide enough bandwidth even when some optical packet switches fail.
