A method for selection by a downstream device of data packets of connections of a network transmitted by at least one upstream device according to a predetermined threshold for quantities of data transmitted by the connections includes: for each connection, initialization by each upstream device of a counter for packets transmitted according to a set of predetermined initial values, with the difference between two initial consecutive values greater than the threshold, then incrementation by a predetermined value for each transmitted packet, defining the current counting value of the packet; reception by the downstream device of each IP packet of each connection, and comparison of the threshold with the difference between the current counting value and the initial value immediately lower than the set of initial values, enabling selection of packets for connections that have transmitted less data than the threshold, compared to packets for connections that have transmitted more.

A method for the selection by a downstream device (3a, 3b, 3c) of data packets in at least one network connection transmitted by at least one upstream device (1) in relation to a predetermined threshold of the quantities of data transmitted through the connection, this method comprising
A system for generating connection of a network data packets, in an upstream device connected to the network, comprising means (8) for the transmission of packets an information processing unit (9) and information storage means (10) comprising at least one register (11) capable of storing the number of transmitted packets, the information processing unit comprising means (9a) for initialising this register to an initial count value at the start of the connection and means (9b) for incrementing the contents of this register whenever a new packet is created and means (9c) for copying this register into a current count value field in the packet header block, characterised in that the initialisation means (9a) comprise means (9d) for selecting the initial count value of at least one connection from a set of predetermined initial values such that the difference between two consecutive initial values in that set is greater than a predetermined threshold.
A system for the transmission of data packets from at least one connection of a network comprising receiving means (12) for packets originating from upstream device, each packet having a current count value in its header block, characterised in that the information processing means (14) also comprise a table (15) of initial count values and means (14a) for calculating the difference between the current count value of the packet received and the initial value in the table immediately below that current count value and means (14b) for comparing this difference with a predetermined threshold.
