This invention relates to the field of packet communications. More particularly, this invention is a method and system for using a jitter absorption buffer to absorb propagation delay variation in packet arrival time. The invention uses a finite state machine with two or more states, such as L (210), M (220), H (230), LR (215), MR (225), and HR (235). State transitions occur based on events such as overflow (3081, 3241, 352), underflow (3081, 3241, 354), half full (316, 336, 356), or time expired (328, 344). According to one embodiment, when the measured delay variation exceeds a threshold, the buffer size is hitlessly increased, and when it is below the threshold, the buffer size is hitlessly decreased.
On peut modifier automatiquement la taille d'un tampon d'absorption de gigue (JAB) (34) en réponse à des changements de l'état d'un réseau. La taille varie en fonction du remplissage du tampon et de ses récentes variations de profondeur. Le réglage automatique permet d'effectuer les corrections adéquates des variations sur le retard des paquets (PDV) tout en évitant les accroissements non nécessaires des retards absolus de paquets (PDV), dus à l'utilisation prolongée d'un JAB surdimensionné. Ce résumé doit servir d'outil de recherche sur les brevets, et ne doit pas être considéré comme une limitation de l'étendue des revendications.
