PURPOSE: Congestion control of AAL2 connections is provided to manage a data packet generated from a frame. CONSTITUTION: The invention concerns a method of managing data packets originating from data frames, the packets being presented to buffer(40) prior to processing. When a packet corresponding to the start of a frame is presented to the buffer stage, it is determined whether the filling level of the buffer(40) exceeds a first predetermined filling threshold(42) corresponding to a state of congestion and, if such is the case, this packet and all packets belonging to that same frame are systematically discarded before the buffer. The frames can e.g. originate from AAL2 connections, and each constitute a respective ATMS adaptation layer service data unit(AAL2 SDU), in which case the packets are common part sublayer(CPS) packets, and the buffer(40) stores the CPS packets before the latter are multiplexed into asynchronous transfer mode(ATM) cells. |
