A method for performing a measurement on data traffic at a node of a communication network. The node includes an input interface and an output interface. The input interface receives first packets and checks whether they are marked. If a first packet is marked, a global input parameter is updated. A partial input parameter is also updated, provided the first packet is addressed to the output interface. The output interface receives second packets, which include at least part of the first packets, and checks whether they are marked. If a second packet is marked, a partial output parameter is updated, provided the second packet is received from the input interface. Further, a global output parameter is updated. The method further performs a measurement on the data traffic based on: global input parameter, partial input parameter, global output parameter, and partial output parameter. |
