ABSTRACT: The real-time control of multiple queues handling traffic of different nature is getting increasing relevance in both the uplink and downlink of wireless telecommunication networks, characterized by the presence of a central access point. Such is the case of satellite networks, with either on-board processing or double-hop configuration, besides a number of terrestrial local and metropolitan wireless networks. Given a certain amount of available bandwidth, the problem is that of deciding, within a certain time frame, the allocation of bandwidth partitions for each traffic queue, whose packets are awaiting transmission; eventually, this determines the transmission rates to be passed to the scheduler and to the physical layer Adaptive Coding and Modulation (ACM) devices. In a satellite network, where this task is accomplished by a master station, residing at the access point, it is possible to take such decisions by means of a centralized controller, based on real-time instanta (literal)
