Abstract: The invention relates to a method and telecommunications system (SYS) for monitoring a data flow (DAT) in a data network (WWW) between at least two telecommunications terminals (TEA, TEB), which are connected to the data network via at least one access server (AAA, AAB). When monitoring, the data flow (DAT) between the telecommunications terminals (TEA, TEB) is rerouted from the access server (AAA, AAB) via a monitoring server (PRO), which makes a copy (KOP) of the data flow (DAT) and transmits it to an evaluation unit (ASW).

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.
