Patent ID: 6925060

Claim:
Method of controlling a flow of at least one TCP connection between a sender ( 10 ) and a receiver ( 20 ), of the type which consists in controlling, at a level of a given multiplexing node across which TCP segments pertaining to a connection pass, a parameter for the window size (Wa) contained in the acknowledgement segments returned by the receiver, wherein the method comprises the steps of: a) receiving ( 100 ) an acknowledgement from the receiver on the up link (receiver to sender) of the connection at the level of said given multiplexing node; b) controlling ( 200 - 600 ) a window size parameter (Wa) contained in said acknowledgement segment on the basis of the difference (Diff) between, firstly, a first context value (NoSegData i ) associated with the TCP connection, defined as being the sequence number of the last segment that was transmitted from said given multiplexing node on the down link (sender to receiver) of the connection, to which the length of said segment is added, and, secondly, the sequence number indicated in said acknowledgement segment; c) transmitting ( 700 ) the acknowledgement segment to the sender on the up link of the connection from said multiplexing node with the window size parameter (Wa) thus controlled.
