TS (Traffic Shaping) is a measure that actively adjusts the traffic output rate. A typical application is to control the output of local traffic based on the TP (Throughput) metric of downstream network nodes. The main difference between traffic shaping and traffic policing is that traffic shaping buffers packets that would be dropped by traffic policing — typically by placing them into a buffer or queue. When the token bucket has enough tokens, these buffered packets are then sent out uniformly. Another difference between traffic shaping and traffic policing is that shaping may increase latency, whereas policing introduces almost no additional latency.
