A dynamic bandwidth allocation system and method for dynamically sharing a communication bandwidth. The system provides a scheduler (310) that enables the method to process bandwith information in a communication system (300). The communication system (300) preferably includes one or more communication arrays, or hubs (320), which are centrally located to provide an airlink between a plurality of physically separated processor-based systems or remote units RUs(330 a-f), or other sources of communication such as voice communication, utilizing a communication device, or node. Each hub (320) and RU (330) includes one or more controllers (340, 350). The scheduler (310) utilizes the controllers (340, 350) to track and process bandwidth information for communicating between the one or more hubs (320) and the plurality of RUs (330 a-f). Each RU (330) generally services a plurality of bursty data traffic sources. The scheduler (310) tracks an airlink communication traffic in both downlink and/or uplink directions to accurately determine airlink bandwidth requests for the plurality of RUs (330 a-f).

L'invention concerne un système et un procédé d'attribution dynamique de largeur de bande permettant de partager de manière dynamique une largeur de bande de communication. Le système comprend un dispositif programmateur (310) permettant de traiter l'information de largeur de bande dans un système (300) de communication à l'aide dudit procédé. Le système (300) de communication comprend, de préférence, une ou plusieurs matrices de communication, ou stations pivot (320), situées de manière centrale et garantissant une liaison aérienne entre plusieurs systèmes processeurs physiquement séparés ou unités éloignées RUs (330 a-f), ou d'autres sources de communication, par exemple la communication vocale, utilisant un dispositif ou noeud de communication. Chaque station pivot (320) et RU (330) comprend un ou plusieurs contrôleurs (340, 350). Le dispositif programmateur (310) utilise les contrôleurs (340, 350) pour suivre et traiter l'information de largeur de bande de communication entre la ou les stations pivot (320) et les diverses RUs (330 a-f). Chaque RU (330) dessert généralement plusieurs sources de trafic de données par rafale. Le dispositif programmateur (310) assure le suivi du trafic de communication par liaison aérienne dans les directions descendante et/ou ascendante afin de déterminer de manière précise les demandes de largeur de bande par liaison aérienne pour les diverses RUs (330 a-f).
