ABSTRACT:
The invention relates to a method and apparatus for scheduling transmission link bandwidth between packet-switched data flows so that a desired CoS (Class of Service) is provided with an ability to utilize the instantaneously available bandwidth of a data transmission network while simultaneously offering a guaranteed minimum data rate (Guaranteed Data Rate and Best Effort) without compromising the operation of such classes that have no guaranteed lower bound of data rate, but instead, have the service implemented by the utilization of the instantaneously available bandwidth (Best Effort). The invention is based utilizing in the scheduler control, not only the information indicating the class of service, but also the information indicating the subgroup inside a class of service (e.g., drop precedence). The information indicating the subgroup is conventionally utilized only for congestion control purposes.
