Network data center and network method for deploying data center

摘要

A network data center, comprising: a group of switches core (1), m groups of gratings of waveguides cyclic matrices CAWG (2a to 2m), m groups of switches edge (4a to 4m) where the m CAWG (2a to 2m) and the m groups of switches edge (4a to 4m) are in a one to one correspondence, the m CAWG (2a to 2m) comprise a first CAWG group, and the m groups of switches edge (4a to 4m) comprises a first set of edge switches, wherein the first group of edge switches is any of the m groups of edge switches, and the first CAWG group is a CAWG group for the first group of edge switches; the switch group core (1) comprises k switches core; the first CAWG (2a to 2m) group comprises 2 * YN * N CAWG, wherein 2 * Y CAWG comprise Y CAWG uplink and Y CAWG downlink, the CAWG and uplink are connected to each switch core group core switches, separately, by using an optical uplink and Y CAWG downlink are connected to each core switch in the switch group core, separately, by using an optical downlink; and the first group of switches edge (4a to 4m) comprises multiple edge switches; each edge switch multiple of edge switches connected to a CAWG uplink and one downlink CAWG the first CAWG group separately; where each of a number of edge switches in the first group of edge switches, a number of ports of each edge switch in the first switch group yk edge, is less than or equal to N.
