This method comprises the use of a memory in which to each virtual circuit is allocated a context (CT) defining the conditions for evaluating the bit rate of this virtual circuit, the reading, upon the reception of a cell, of the context of the virtual circuit, the use of a clock set aside in order to supply a current time associated with this virtual circuit, and of bit rate measuring means supplying, upon the arrival of a cell, a measurement of bit rate of the virtual circuit of this cell.
<??>The context (CT) comprises at least one bit rate threshold and there is provision for comparing such a bit rate measurement with this threshold and for actuating a counter of crossovers, in a first direction, if this threshold is reached or crossed, or in another direction, if this threshold is not reached, as well as for determining whether such an actuation has brought the counter of crossovers into an extreme position of the said first direction, and for then supplying a signal (OSC) indicating the need for a corrective action.
