<p>The invention relates to a method for monitoring a statistical multiplexed data stream (1) for compliance with an announced property indicative of the granularity of the data stream (1), in particular an announced equivalent access bandwidth (b x ), comprising the steps of: determining a theoretical bandwidth (B th ) derived from the data stream (1) based on the announced property, on a long-term mean value (M x ) of the data stream (1), and on a preset factor N, determining an instantaneous bandwidth (B in ) derived from the data stream (1) by counting the occupation of a sliding window over a corresponding number N of time slots of the data stream (1), and comparing the theoretical bandwidth (B th ) to the instantaneous bandwidth (B in ). The invention further relates to a monitoring device (10) for performing the method and to a gateway (2) comprising such a monitoring device (10).</p> |
