Abstract:
1. A system comprising: a transmit queue that receives data from traffic sources; a traffic shaper coupled to said transmit queue, said traffic shaper comprising a shaper controller, a shaper core, parameter storage, and bucket value storage, said shaper core shaping said data to determine if cell requests can be scheduled based said shaper controller accessing quality of service (QoS) parameter values (Pn) in said parameter storage and bucket values (Bn) in said bucket value storage and controlling their transmission to said shaper core; a scheduler coupled to said transmit queue and said traffic shaper that schedules transmission of said data to customer premise equipment (CPE) based on receiving cell request signals from said traffic shaper; a shaping interval time (SIT) counter coupled to said shaper controller and said shaper core, said SIT counter transmitting a signal (SITn) that initiates when said shaper controller accesses said Pn and Bn values; and a host controller coupled to said parameter storage and said scheduler that initializes said parameter storage and said scheduler.
