Traffic monitoring in a packet-switched communication network

A method for monitoring packets in a communication network includes at an ingress point, classifying at least one packet of a traffic received at the ingress point for determining whether packets of the traffic are to be monitored and, in the affirmative, associating them with a service of monitoring; at the ingress point, creating a selection policy to identify a packet flow of the packets to be monitored according to the service of monitoring. The method also includes installing the selection policy at one or more measuring points within the communication network, and at each measuring point, identifying the packet flow on the basis of the selection policy. The method further includes at each measuring point, applying monitoring actions associated with the service of monitoring to the identified packet flow.
