Communications internetwork system connecting a client node array to a resource array

A method for routing data between resources and client stations comprising steps of:

• connecting client stations in a plurality of individual client networks;
• connecting each individual client network to a data interface at a client communication node comprising a microprocessor, data routing circuitry, and a random access memory, the client communication nodes forming a client array of communication nodes;
• forming a resource array of resource communication nodes having the same number of resource nodes as client nodes in the client array, each resource node comprising a microprocessor, data routing circuitry, and a random access memory;
• connecting each client node to exactly four other client nodes by data transfer links and to just one resource communication node by a data transfer link;
• and
• connecting each resource node to exactly four other resource nodes by data transfer links and to just one resource trunk leading to addressable resources by a data transfer link.
