Figure 3 shows how the QoS module processes traffic:
Traffic classifier identifies and classifies traffic for subsequent QoS actions.
The QoS module takes various QoS actions on classified traffic as configured,
depending on the traffic processing phase and network status. For example, you
may configure the QoS module to perform traffic policing for incoming traffic,
traffic shaping for outgoing traffic, congestion avoidance before congestion
occurs, and congestion management when congestion occurs.
