Patent ID: 7944831

Claim:
A data communication network, comprising: an m-dimensional (m is a natural number no smaller than 3) interchange structure based on an m-dimensional hyperhub structure in which core nodes contained in the m-dimensional hyperhub structure are directly connected, wherein the core nodes are divided into m groups, the m-dimensional coordinates (J 1 , J 2 , J 3 , J 4 , J 5 , . . . , Jm−1, Jm) of the core nodes belonging to a p-th group satisfy the condition that Jp is zero, the m-dimensional coordinates (j 1 , j 2 , j 3 , j 4 , j 5 , . . . , jm−1, jm) of the core nodes belonging to a q-th group satisfy the condition that jq is zero, and a core node belonging to the p-th group is directly connected to a core node belonging to the q-th group and is not directly connected to other core nodes belonging to the p-th group, wherein at least one of the core nodes comprises a switch having input ports for receiving data and output ports for sending data.
