ABSTRACT:
The switching network (SN) includes a plurality of intercoupled switching units (SU) and a communication path (VP) established by a path set up cell (PSUC). In the switching units (SU) the communication path is routed through the cell marked with a first tag (ID) included in the path set up cell (PSUC), thereby providing the possibility for a second communication path to be set up later by a second path set up cell including a second tag (ID, DISL1) with the same value as the first tag (ID), in such a way that it does not cross the first mentioned communication path (VP) or that it crosses it at most a predetermined number of times, as indicated by a counter (CO, C1) also included in the second path set up cell.
