According to the inventive method, IP packets are received, identified, evaluated and processed at interfaces of a network node in a communications network, which comprises a number of network nodes and which transmits IP packets. The invention provides that in an in-band IP signaling packet, which is received at an interface of the network node, is identified there, and which is characterized by an entry in the protocol field of the header of the IP packet, a one-to- one value, which is assigned to the receiving interface and which differs from the values of the other interfaces is entered in a specified field of the IP header of the IP packet, and the packet that is modified in such a manner is output to the control component.
