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. |

1. A data center network, comprising:
one core switch group; and m cyclic arrayed waveguide grating (CAWG) groups; and m edge switch groups, wherein the m CAWG groups and the m edge switch groups are in a one-to-one correspondence, wherein the m CAWG groups comprise a first CAWG group, wherein the m edge switch groups comprise a first edge switch group, wherein the first edge switch group is any one of the m edge switch groups, wherein the first CAWG group is a CAWG group corresponding to the first edge switch group, wherein the core switch group comprises k core switches, wherein the first CAWG group comprises 2*Y N*N CAWGs, wherein the 2*Y CAWGs comprise Y uplink CAWGs and Y downlink CAWGs, wherein the Y uplink CAWGs are connected to each core switch in the core switch group separately by using an optical uplink, wherein the Y downlink CAWGs are connected to each core switch in the core switch group separately by using an optical downlink, and wherein the first edge switch group comprises multiple edge switches, wherein each edge switch of the multiple edge switches is connected to an uplink CAWG and a downlink CAWG in the first CAWG group separately, wherein any one of the number of edge switches in the first edge switch group, a number of ports of each edge switch in the first edge switch group, and k are less than or equal to N. |
