A device (DGM) is dedicated to the management of parameter measurements, type of end-to-end, to a management system (NMS) of a packet-oriented communications network comprising a plurality of peripheral devices ( EP). The device (DGM) comprises i) management means (MG) adapted to transmit to peripheral equipment (PE) chosen selected filter definitions associated with the selected filter identifiers, ii) correlation means adapted to correlate each notification having a selected filter identifier, received from an input peripheral equipment (PE-1), with a selected set of notifications received output peripherals (EP-2, EP-3) and having an identifier of filter having at least one relationship with the selected filter identifier, and iii) calculation means (MCM) responsible for issuing parameter measurements from the values contained in the correlated notifications.
