method and device for providing users with guaranteed data rate communications bandwidth will carry voice traffic. based on prioritu00e4tszuweisung
A communications system operator provides to each user of a multi-user communications system a committed information rate (CIR). When a user requests bandwidth for transmission, a system controller queues the user in a high-priority subclass A. The system controller allocates bandwidth to the user at the head of the queue as requested but if the user's bandwidth, measured as an average over a sampling time, exceeds its CIR, it is moved into a low-priority subclass B. The user can then only obtain further bandwidth after other users in the high-priority subclass have been allocated bandwidth up to their CIRs. If a user in the low-priority subclass only receives allocation of a small amount of bandwidth, so that its average information rate falls below its CIR, it is moved back into the queue in the high-priority subclass.
