Overview

Traffic policing, traffic shaping, and rate limit are QoS techniques that help assign network resources, such as assign bandwidth. They increase network performance and user satisfaction. For example, you can configure a flow to use only the resources committed to it in a certain time range. This avoids network congestion caused by burst traffic.

Traffic policing and generic traffic shaping (GTS) limit the traffic rate and resource usage according to traffic specifications. Once a particular flow exceeds its specifications, such as assigned bandwidth, the flow is shaped or policed to make sure that it is under the specifications. You can use token buckets for evaluating traffic specifications.
