Client based congestion control mechanism

摘要

The invention concerns a method of notifying control information to a congestion control mechanism in charge of controlling data segments sending rate of a server towards a client. The control information includes loss events where a loss event corresponds to one or more data segments lost. The method comprises a step of receiving data segments into a reception buffer at the client, a step of detecting loss events from the received data segments and a step of notifying the congestion control mechanism with a number of loss events that is dependent on the number of detected loss events and a measure of criticality related to the reception of the data segments by the client. The measure of criticality can be derived from the filling level of the reception buffer, the reception of data segments being in a critical state when the reception buffer is experiencing overflow or underflow conditions.
