Traffic policing, traffic shaping are key factors in implementing QoS. Traffic policing controls the rate of incoming packets to ensure that network resources are properly allocated. Traffic shaping controls the rate of outgoing packets to allow the traffic rate to match that on the downstream device. These factors work together to provide QoS guarantees on …
