Abstract
A method and device for determining the presence of a rate limiting mechanism arranged between a sending and a receiving data communication node in a data transfer path of a communication network is presented. The method includes determining time difference values for probe packets in a train of probe packets sent from the sending node and received in the receiving node after having traversed the data transfer path during real-time operation of the data transfer path. The method further includes determining the presence of a rate limiting mechanism in the data transfer path upon detecting that an increase in the time difference value between received probe packets in the train of probe packets exceeds a threshold criterion. Other methods and devices for determining the absence of a rate limiting mechanism and corresponding computer program products are further disclosed.
