Abstract
A scheduler having improved fairness is disclosed, for scheduling packets or other data blocks for transmission from a plurality of transmission elements in timeslots in a communication system. The scheduler determines credit measures for respective ones of the transmission elements, with each of said credit measures being a function of a reserved portion of an available bandwidth and a scheduled portion of said available bandwidth for a corresponding one of the transmission elements. The scheduler selects one or more of the transmission elements for scheduling in a given one of the timeslots based on the credit measures. The scheduler in an illustrative embodiment may be implemented in a network processor integrated circuit or other processing device of the communication system.
