Patent ID: 11102110

Abstract:
A DCN includes N first-level subnetworks, each first-level subnetwork includes N second-level subnetworks, each kth-level subnetwork includes N (k+1)th-level subnetworks, each (K−1)th-level subnetwork includes multiple switches, and the DCN is a K-level network; each switch in the DCN has K subnetwork identifiers, the K subnetwork identifiers are respectively used to indicate each level of subnetwork to which the switch belongs and a number in a (K−1)th-level subnetwork to which the switch belongs; and the switch is separately interconnected with each switch in K direct connection switch groups, each direct connection switch group includes N−1 switches, and an ith-level subnetwork identifier of the N−1 switches included in an ith direct connection switch group of the K direct connection switch groups is different from an ith-level subnetwork identifier of the switch, and is the same as other K−1 subnetwork identifiers of the switch.
