Abstract
The method of identifying, in a memory space of the node, a virtual circuit of a network to which the cell belongs, on the basis of virtual path numbers VPI and virtual channel numbers VCI contained in the header of the cell. This method includes PA1 addressing the memory space of the node on the basis of the virtual path number VPI contained in the header of the cell to identify a first context zone in this space indicating the range of virtual channels that can be used by the cell for this VPI, PA1 and addressing a second context zone on the basis of a virtual channel number VCI contained in the header of the cell and a basic address read in the first context zone to obtain the list of directions to be taken by the cell at the exit from the node, as well as the new header.
