Traffic Shaping by a Job Buffer in a Token-Bank Rate-Control Throttle

Rate-control throttles with token banks or leaky buckets have been used for overload control in telecommunication systems and have been recommended for traffic policing in Broadband Integrated Services Digital Networks (B-ISDN's). Enhancing the token-bank throttle with a buffer to shape the admitted traffic has been suggested. Researchers have shown that the presence of the buffer can dramatically reduce the squared coefficient of variation of the interadmission time.
