1. A method for use in a first node of a transport network for supporting latency monitoring in the transport network, the transport network transporting traffic to and from at least one wireless base station, the transport network comprising the first node and a second node, the method comprising:
determining a first timestamp representing a time at which a data element is received at the first node;
adding information representative of the first timestamp to a communication signal for sending to the second node, the communication signal carrying data for the at least one wireless base station, the data including the received data element; and
sending an indication of an association between the information representative of the first timestamp and the data element that the information representative of the first timestamp relates to.
