We propose a partial shaping mechanism (PSM) built upon the continuous-state leaky bucket (LB) mechanism which can control the shaping delay and the output buffer size. We assume that input traffic of the proposed shaping mechanism is the worst case traffic tolerated by the continuous-state LB mechanism and characterize traffic patterns that can depart from our shaping mechanism. We also compare shaping delay and output buffer size of the proposed shaping mechanism with the existing shaping mechanism which holds peak emission time strictly. Our results show that the proposed shaping mechanism can easily manage the shaping delay and the output buffer size than other mechanisms.
