摘要

Congestion control in a telecommunications network, in which a method of congestion control in a transport network is provided. A buffer state of a buffer is monitored by dynamically sampling the buffer such that the sampling rate is adjusted in dependence of the buffer state. Also, a condition indicative of congestion is determined in response to a change of the buffer state exceeding a predetermined limit. In response to determining the condition indicative of congestion, a congestion notification message is created. The created congestion notification message may then be transmitted to a second network node. The second network node may subsequently compensate for a detected congestion on the basis of a received congestion notification message.

說(shuō)明書(shū)

The flow identifier 310 may identify at least one flow that contributes to congestion. The back-off information 320 may indicate a suitable back-off to compensate for the congestion caused by the at least one flow associated with the corresponding flow identifier 310.
