Configuring Traditional QoS Functions
Context
Diversified services result in a sharp increase in network traffic, which may cause network congestion, increase forwarding delay, or even packet loss. Any of the preceding situations will cause service quality deterioration or even service interruption. Therefore, network congestion must be eliminated for real-time services. The best solution is to increase network bandwidth, which is, however, cost-ineffective. The most cost-effective way is to use an "assured" policy to manage traffic.
Quality of Service (QoS) provides end-to-end service quality assurance to meet different service requirements. It helps improve network resource utilization and allows different types of traffic to compete for network resources based on their priorities, so that voice, video, and important data applications are processed preferentially on network devices.
A traffic classifier defines a group of matching rules to classify packets. A traffic behavior defines an action to be performed on packets of a specified type. A traffic policy binds traffic classifiers and traffic behaviors, and then performs the actions defined in traffic behaviors on classified packets.
