ABSTRACT:
A system schedules traffic flows on an output port using a circular memory structure. The circular memory structure may be a rate wheel that includes a group of sequentially arranged slots. The rate wheel schedules the traffic flows in select ones of the slots based on traffic shaping parameters assigned to the flows. The rate wheel compensates for collisions between multiple flows that occur in the slots by subsequently skipping empty slots.
