摘要： The present invention relates to a marking determining method and a related device for determining a packet marking of packets of an incoming packet-flow, in order to keep the packets in conformance with a traffic policy. The determining is based on an actual value of a traffic reservation parameter, while the traffic reservation parameter is a measure of available network resources dedicated to packets of said incoming packet-flow having a pre-assigned priority. The determining further is based on the pre-assigned priority of the packets of the incoming packet flow. The marking method a first steps of holding a threshold value for the traffic reservation parameter, while the threshold value is lying between a minimum and a maximum value of the traffic reservation parameter. A second step is the metering the actual value of the traffic reservation parameter and a last step of determining the packet marking of the packets only based on the actual value of the traffic reservation parameter if the actual value of the traffic reservation parameter exceeds the threshold value for the traffic reservation parameter.

摘要： The invention relates to a method for use in a telecommunication system to generate an acceptance decision during a decision cycle that comprises whether to accept an incoming packet of a data stream or not in a buffer (BUF). The incoming packet (P) has a drop priority (DP) being one of a plurality of arranged drop priorities. The method comprises determining for a drop priority parameter (DPP) an actual drop priority parameter value (DPPact) out of the plurality of drop priorities; and comparing the drop priority parameter (DPP) with the drop priority (DP) of the packet (P) in order to generate the acceptance decision. The method further comprises that the step of determining the actual drop priority parameter value (DPPact) comprises determining a previous drop priority parameter value (DPPprev) by means of any one of an initial value (DPPinit) and a previous actual drop priority parameter value (DPPact′) having been determined during one of a previous decision cycle; and updating a queue occupancy variable (Q) as a function of a previous re-scaled queue occupancy value (RE-Qact′) having been determined during one of a previous decision cycle and providing thereby an intermediate queue occupancy value (Qint); and re-calculating the intermediate queue occupancy value (Qint) of the queue occupancy variable (Q) in function of instantaneous queue occupancy information (INF-Qins) of the buffer (BUF) and providing thereby an actual queue occupancy value (Qact); and comparing the actual queue occupancy value (Qact) with any one of a minimum threshold (Tmin) and a maximum threshold (Tmax) and providing thereby a result (RES (UP; DO; REM)); and according to the (RES (UP; DO; RET)) re-scaling the actual queue occupancy value (Qact) and the previous drop priority parameter value (DPPprev) and providing thereby, respectively, a re-scaled queue occupancy value (RE-Qact) and the actual drop priority parameter value (DPPact).
