ABSTRACT:
A grid-based mesh network with even numbers of alternatingly directed rows and columns. Devices are attached by way of nodes which exist at the intersections of rows and columns. The extremes of the grid are connected to form a three-dimensional network on the surface of a sphere. The strategy at each node requires that every packet arriving on an incoming link must leave on an outgoing link, so there is no need for any packet buffering in the node. Described herein are several routing algorithms, an alternative to sequential addressing, a method for adding nodes to the network, ways to deal with failed nodes and links, a hierarchically structured network, and a scheme for efficiently transferring files of more than one packet.
