Method for managing a distribution of bandwidth in a communications network, corresponding storage means and slave node

Computer-readable storage means storing a computer program comprising a set of instructions executable by a computer for implementing a method for managing access to a communications network clocked in transmission cycles by a master node wherein, during a given transmission cycle, a slave node of said network performs steps for:

• obtaining an active access sequence applicable to said given transmission cycle and a piece of information on duration of relevance associated with said active access sequence obtained;
• carrying out a first check that at least one packet is received by said slave node during the given transmission cycle, according to said 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 said 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 said piece of information on duration of relevance associated with the active access sequence obtained.

Slave node belonging to a communications network clocked in transmission cycles by a master node wherein it comprises:

• means for obtaining an active access sequence applicable to said given transmission cycle and a piece of information on duration of relevance associated with said active access sequence obtained;
• means for checking that at least one packet is received by said slave node during the given transmission cycle, according to said active access sequence;
• first means for determining an access sequence for a following transmission cycle as a function of pieces of information contained in said received packet or packets, said first means for determining being activated in the event of a positive first check;
• second means for determining an access sequence for the following transmission cycle as a function of said piece of information on duration of relevance associated with the active access sequence obtained, said second means for determining being activated in the event of a negative first check.
