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.
Claims5
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.
