Abstract: In order to detect congestion on a transmission link, endpoint items of network equipment are associated with congestion-detection applications. Per class of service, one application sends to the other control messages indicating volumes of data transmitted by the concerned item of network equipment via the transmission link. On reception of the control messages, the other application obtains information on volumes of data received by the other item of network equipment. By determining a first divergence in volumes of data transmitted between two control messages and a second divergence in volumes of data received, between two control messages, this other application is able to detect a situation of congestion on the transmission link occurring for one or more classes of service, and to generate an alarm signal accordingly.
