Abstract:
A method for detecting congestion in a transport network is provided. The congestion detection utilizes flow control including relative bitrate. The method comprises counting the number of detected frame loss events for a flow. The method further comprises determining if the number of detected frame losses is greater than or equal to a corresponding threshold, wherein the threshold used is an individual threshold for the flow set taking into account relative bitrate weights of the flow, and detecting transport network congestion for the flow when the number of detected frame losses is greater than or equal to the corresponding threshold.
