1. A network for use in routing data from a source node having an associated source address to a destination node having an associated destination address, said network comprising:
- a plurality of nodes which route and store said data, each of said nodes being associated with a node address, wherein said nodes are selectable from the types of stub, transit and region border;
a number of ports contained within each of said nodes, each of said ports being associated with a port address;
a plurality of regions, each of said regions comprising a number of said nodes and each region being associated with a region address of a minimum bit length;
a switching element which routes said data from one of said plurality of regions to another of said plurality of regions based on said region addresses wherein said data includes an addressing scheme in which said source address comprises bit fields for a source port address, a source node address and a source region address and said destination address comprises bit fields for a destination port address, a destination node address and a destination region address.

Abstract
A data communication method enables the transfer of data having different protocols without requiring increased bandwidth in the transmission line. The system efficiently re-routes data in the event of network alterations and determines a fast and efficient way to transport data based on the then-existing network structure using link-state and distance vector techniques.
