The system then identifies a next hop router from a router table if router identification information is associated with the data. Otherwise, the system identifies a next hop router from a routing table if router identification information is not associated with the data. When identifying a next hop router from the router table, the system determines whether a match exists between entries in the router table and the router identification information. The system may set a switch tag in the data packet, in which the switch tag corresponds to a destination router identification. The router table used by the system contains information regarding how to reach all known routers.Field of SearchSwitching a message which includes an address headerProcessing of address header for routing, per se Employing logical addressing for routing (e.g., VP or VC) Employing logical addressing for routing (e.g., VP or VC) Employing logical addressing for routing (e.g., VP or VC) Bridge or gateway between networks Least cost or minimum delay routing Including signaling between network elements PATHFINDING OR ROUTING Combined circuit switching and packet switching Having a plurality of nodes performing distributed switching Plurality of rings or loops to form a mesh network Interconnected star couplers Nodes interconnected in hierarchy to form a tree Alternate path routing Prioritized data routing Least weight routing COMPUTER-TO-COMPUTER DATA ROUTING | |
