<p>A data communication network having node arrays (0,1,2,3,4) with each node array having nodes (01-43) coupled with data systems (010-421) served by the network. Each array node is interconnected by secondary transmission paths to (012,023,031-412,423,431) each other array node for exchanging data between array nodes. In addition, each array node is interconnected by primary transmission paths (0111.0212,0313-4101,4202,4303) with a corresponding array node of adjacent node arrays for use in establishing ring transmission paths between node arrays with each ring transmission path interconnecting corresponding array nodes. Control apparatus selectively interconnect primary transmission paths and secondary transmission paths in a precedence order to establish network communication paths between the data systems. <IMAGE></p> |
