Abstract
A data center network and a method for deploying the data center network. The data center network includes one core switch group, m cyclic arrayed waveguide grating (CAWG) groups, and m edge switch groups, where the core switch group includes k core switches; each CAWG group includes 2*Y N*N CAWGs, where the 2*Y CAWGs include Y uplink CAWGs and Y downlink CAWGs, the Y uplink CAWGs are connected to each core switch in the core switch group separately using an optical uplink, and the Y downlink CAWGs are connected to each core switch in the core switch group separately using an optical downlink; and each edge switch of an edge switch group is connected to an uplink CAWG and a downlink CAWG in a corresponding CAWG group separately. The present invention can reduce the number of optical fibers in a data center network.
