A medium access protocol which adjusts number of contention slots in a variable length frame and superimposes a variable window structure over the frame structure. The number of contention slots (24) in a frame (28, 30) is changed on a frame by frame basis by determining if a collision occurred in any contention slot (44). If not the contention slot is removed (48) and if so, the number of slots is increased (52). In high traffic situations, if the average load is greater than a threshold (107, 120) the number of frames in a window is increased (130). If the load drops below the threshold (120), the number of frames per window is decreased (124).

L'invention concerne un protocole d'accès à un support, permettant d'ajuster le nombre de fentes de contention dans une trame de longueur variable et de superposer une structure de fenêtre variable sur la structure de trame. On peut changer le nombre de fentes (24) de contention d'une trame (28, 30) trame par trame en déterminant si une collision s'est produite dans une quelconque fente (44) de contention. Si ce n'est pas le cas, on enlève (48) la fente de contention, et si tel est le cas, on augmente (52) le nombre de fentes. Dans des situations de trafic intense, si la charge moyenne est supérieure à un seuil (107, 120), on augmente (130) le nombre de trames dans une fenêtre. Si la charge est inférieure au seuil (120), le nombre de trames par fenêtre est réduit (124).
