Explanation
Traffic shaping buffers/queues excess traffic and releases it at a rate that does not exceed the configured limit (in this case 50 Mbps). Unlike policing, which drops or re-marks packets that exceed the rate, shaping delays them - meaning traffic still gets through, just paced to stay within the circuit's allowable bandwidth. This prevents the ISP from dropping packets due to exceeding the committed rate. Policing would drop excess traffic rather than buffering it. CIR (Committed Information Rate) is a concept/parameter, not a mechanism. Rate-limit is a generic term often synonymous with policing.
