The invention concerns a data traffic politer (POL) included in a telecommunication network to police data traffic. The data traffic includes data packets that are part of a lower order data flow that is on its turn part of a higher order data flow. Each data packet is associated to a lower order identifier (LOI) that identifies the lower order data flow and to a higher order identifier that (HOI) identifies the higher order data flow. The politer (POL) includes first determining means (DET1) coupled to an input of the politer (POL) to determine, upon reception of a data packet, its lower order identifier (LOI). A first control means (CTRL1) coupled to the first determining means (DET1) checks a conformance of the data packet according to predefined lower order conformance rules (LOC(LOI)) associated to its lower order identifier (LOI) and provides thereby a lower order conformance result (LOCK) that is lower order conforming or lower order non-conforming. Furthermore the politer (POL) includes second determining means (DET2) coupled to the input to determine the higher order identifier (HOI) that is associated to the data packet and forwards the higher order identifier (HOI) to a second control means (CTRL2). The second control means (CTRL2) checks a conformance of the data packet according to predefined higher order conformance rules (HOC(HOI)) associated to the higher order identifier (HOI) and provides a higher order conformance result (HOCR) that is higher order conforming or higher order non-conforming. The politer (POL) includes declaring means (DECL) coupled between the first control means (CTRL1), the second control means (CTRL2) and an output (OUT) of the politer (POL). The declaring means (DECL) declares, in the event when the lower order conformance result (LOCR) is lower order non-conforming, and the higher order conformance result (HOCK) is higher order conforming, the data packet as conforming. Hereby, when being transmitted, the data packet uses some leftover bandwidth from another lower order data flow within the higher order data flow.
