Congestion management.
Congestion avoidance.
The following section briefly introduces these QoS techniques.
All QoS techniques in this document are based on the DiffServ model.
Deploying QoS in a network

As shown in Figure 2, traffic classification, traffic shaping, traffic policing, congestion management,
and congestion avoidance mainly implement the following features:
Traffic classification—Uses match criteria to assign packets with the same characteristics to
a traffic class. Based on traffic classes, you can provide differentiated services.
Traffic policing—Polices flows and imposes penalties to prevent aggressive use of network
resources. You can apply traffic policing to both incoming and outgoing traffic of a port.
Traffic shaping—Adapts the output rate of traffic to the network resources available on the
downstream device to eliminate packet drops. Traffic shaping usually applies to the outgoing
traffic of a port.
Congestion management—Provides a resource scheduling policy to determine the packet
forwarding sequence when congestion occurs. Congestion management usually applies to the
outgoing traffic of a port.
Congestion avoidance—Monitors the network resource usage. It is usually applied to the
outgoing traffic of a port. When congestion worsens, congestion avoidance reduces the queue
length by dropping packets.
