Abstract
A memory (MCT) is used in which a location is assigned to each virtual circuit, this location containing a context (CT) that defines the evaluation conditions of the throughput of the virtual circuit and, upon reception of each cell, providing for the context relating to the virtual circuit to which the cell belongs to be read, for the purpose of evaluating the throughput of the virtual circuit. A clock signal (BC) is used to supply a current time associated with this virtual circuit. An indication of the start time is written into the context (CT) for a virtual circuit and, upon arrival of a cell for this virtual circuit, the context is read and from the current time supplied by the clock signal, the start time supplied by the read context is subtracted and the thus established time difference is used as a measurement of instantaneous throughput of the virtual circuit, defined as the time interval that has elapsed between two cells, this measurement of instantaneous throughput being supplied to an evaluation circuit (BT), while the current time is written into the context as the start time.
