摘要： A method is disclosed for determining the shortest paths between a source node and a destination node in a network wherein the paths satisfy imposed system constraints. In accordance with the method of the invention, candidate paths are evaluated by accumulating system parameter information from a source node and projecting the system parameter information ahead to the destination node. When the accumulated and projected system parameter information for the candidate path satisfies the imposed system constraints, the candidate path is saved for further evaluation. The candidate paths are sorted in the order such that those paths most-likely to have the shortest lengths and satisfy the imposed system constraint are evaluated first. In one embodiment of the invention, candidate paths that fail to satisfy the imposed system constraints are removed from further processing. Thus, only candidate paths that have at least one complete path that satisfies the imposed system constraints are evaluated further.

摘要： A method of on-line routing of permanent virtual circuits is disclosed. The method uses an exponential cost function based on the network state and virtual circuit parameters to determine paths for the virtual circuits without scaling. The method may also advantageously use information available when multiple virtual circuits are requested to determine paths for the virtual circuits. Additionally, the method allows the routing selection to be refined so that the total cost of routing all the virtual circuits is reduced.

摘要： A method of routing a requested virtual circuit in a network advantageously uses information about concurrent requests for other virtual circuits. Each virtual circuit request in a set of concurrent requests is specified by one or more parameters and each virtual circuit request is routed as a function of one or more parameters of a plurality of the requests. Thereafter, the routing of each request in the set of requests is refined according to a cost function so that the total cost of routing is reduced.
