Patent CA-2187242-C (CA)
Title: A method of admission control and routing of virtual circuits
Inventor: GAWLICK RAINER
IPC: H04L12/56
Filed: 1996-10-07
Granted: 2001-12-18
Abstract: A method of admitting and routing switched virtual circuit requests in a network first finds a set of routing paths on which a requested VC may be routed by using a two step process. The method uses a cost function based on a parameter related to the number of hops in a subset of VC connections previously made in the network to determine potential routing paths on which the VC can be routed at a cost below a specified threshold. The method next checks to determine which potentialrouting paths comprise links and nodes with sufficient resources to accommodate the request. Paths satisfying both steps are output as a set of routing paths and then a second criterion is used to select a path from the set on which to route the request. In a distributed routing system, the inventive method uses a local network state todetermine the cost function and the set of routing paths. The method further updates local state information at nodes along a path selected from the set and permits other paths from the set to be selected for routing a requested VC if the previously selected path has insufficient resources to accommodate the request.

Granted: 2004-04-27
Abstract: The present invention relates to a method and a device for extracting information from a database, which comprises a plurality of data records, each data record comprising at least two data elements, each data element being defined by a data element type and a data element value. First, the data records are read into the primary memory of a computer, so that all processing of the data may be done off line. Then, the data element values are binary-coded and stored in one or more tables. When the selection of at least one data element value is detected, all binary-coded data element values are examined to obtain all data records implied by the selection. Due to the binary-coding, these data records are found very quickly. Finally the data element values implied by the selection is kept track of in a status set.
