Patent ID: 7660320

Claim:
A communication network comprising a plurality of network nodes; wherein the network nodes are logically arranged to form a plurality of concentric rings, all rings except the outermost ring being fully constructed; the number of nodes on each fully constructed ring being d D , wherein d denotes the base of an integer having D digits, D>1, and wherein D also denotes the ring number, D starting with the value 1 for the innermost ring; each node being identified by an identification number unique in the network, said identification number having D digits, D>1, and D denoting the ring number on which the node is located, and the value of each digit being between 0 and d-1; and each node of a given fully constructed ring is allowed to route data packets: to one node in the next inner ring, to d nodes in the next outer ring, if the next outer ring is fully constructed, to at least d nodes on the same ring.
