ABSTRACT:
The invention relates to a communication network with at least two network nodes, with transmission channels for transmitting data packets between the network nodes, and with at least one active coupler. The invention provides for coupler information to be attached to the data packets as they pass through the active coupler, and data-packet running-time information to be determined from the coupler information in a network node that receives a data packet.
