Abstract

This invention relates to the field of communications systems. More particularly, this invention is a system and method for subdividing a class of service data flow into multiple subflows. A modem downloads a configuration file (182). A packet ready for transmission is examined to determine the class of service associated therewith (186). Once the class of service is determined, a subflow bucket associated with the packet is checked (188). If sufficient tokens are available within the bucket, the appropriate number of tokens are assigned to the packet (190, 192). The packet is then transmitted (194). If a sufficient number of tokens are not available in the bucket, the packet is held in queue, and the next queued packet is examined (190, 186).
