Abstract
ystem and method for transfer of real-time traffic in multi-service packet switching communication networks. The system consists of a peak-rate policer (62) at the edge nodes (50), and an output queueing system (70) consists of two queues in series, a smoothing queue (78) and a final queue (84). Smoothing is performed on the first through a smoothing controller (82), while a packet scheduler (92) serves the second, as well as the queues of other supposrted services, at least the best-effort queue (96), driven by an adaptive tracker (88). The adaptive tracker (88) in order to produce periodically the driving signal (90) samples the occupancy of the final queue (86) and is synchronised with the smoothing controller (82), while the smoothingperiod is a multiple of the tracking preiod. The service method is based on tracking of an occupancy target of the final queue and provides explicit guarantees on the delay and the delay jitter, as well as constant 100 % bandwidth allocation utilisation. Alternatively, if the adaptive tracker (88) is replaced by an adaptive predictor (184), the service method can provide, apart from qualti of service guarantees, the following of a selectable less-maximum allocation utilisation target.
