Abstract
A method is proposed for managing access to a communications network clocked in transmission cycles by a master node characterized in that, during a given transmission cycle, a slave node of the network performs steps for: obtaining () an active access sequence applicable for the given transmission cycle and a piece of information on duration of relevance associated with the active access sequence obtained; carrying out () a first check that at least one packet is received by the slave node during the given transmission cycle, according to the active access sequence; in the event of a positive first check, determining () an access sequence for a following transmission cycle as a function of pieces of information contained in the received packet or packets; in the event of a negative first check, determining () an access sequence for the following transmission cycle as a function of the piece of information on duration of relevance associated with the active access sequence obtained.
