A method of estimating available capacity of a data transfer path (16) that transfers data between a sending (12) and a receiving (14) data communication node of a data communication system (10) is disclosed. The method comprising: sending one or more setting packets (15), wherein the one or more setting packets is/are used to set a traffic shaping node arranged in the data transfer path in a steady state; transmitting, from the traffic shaping node, probe packets received from the sending node (12), towards the receiving node (14) at an average rate for the traffic shaping node; providing, in response to traversal of the data transfer path (16) by the probe packets, and during the real-time operation of the data transfer path (16), measured data for use in estimating the available capacity of the data transfer path (16); and estimating the available capacity of the data transfer path (16) using the measured data from the probe packets. |
