  • Patent number: 6891943
    Abstract: In a method for determining a suitable connecting path in a communication network as well as to a corresponding switching equipment, given the presence of a connection inquiry to a requested destination node, a check is first carried out to see whether a suitable connecting path to the requested destination node is already stored in a corresponding dynamic memory. When this is not the case, a suitable connecting path is determined on the basis of stored network data of the communication network and is subsequently entered in the dynamic memory, so that this connecting path is subsequently available for further connecting path determinations. After determining a suitable connecting path, the connection to the requested destination node is set up according to the determined connecting path.

  • Patent number: 6158006
    Abstract: Complex resource configurations often exist in multiprocessor systems. As a result thereof, coordination problems arise given competing accesses to a specific resource configuration by a plurality of processors. In a method for the coordination of parallel accesses of a plurality of processors to resource configurations a central security table is introduced. A processor must deposit its processor number thereat for a specific security number if the processor is to receive control over the resource configuration belonging to this security number.
