ABSTRACT:
A policing device is proposed in which a plurality of parallel police processors (PP1, PP2) are included each of which implements a Modified Virtual Scheduling Algorithm and is so able to derive for a cell for which it is activated by an enabling circuit (EC) a conformance signals (CS1, CS2). An arbitration module (AM) generates from the latter signals, a plurality of which may be provided per cell of the input ATM stream (IN), a discard signal (DS) indicating wether or not such a cell may be inserted into an output stream (OUT) by a discard circuit (DC) as well as feedback signals (FS1, FS2) which indicate to a corresponding processor whether or not to carry out an already prepared update of a predicted arrival time used in the above mentioned algorithm. The architecture of the present policing device is very generic in that it allows implementation of any policing method by straightforwardly adapting the arbitration module and the enabling circuit.
