Through the classification of messages, we can identify and distinguish different types of messages, and adopt different processing methods according to different types to meet different service quality requirements.
For example, some messages may require higher priority for faster transmission, while others may require lower priority for slower transmission. Through traffic classification, this differential treatment can be achieved to meet different service quality requirements. In addition, traffic classification can also be used for traffic supervision, traffic shaping and other operations, so as to achieve the purpose of controlling network traffic and ensuring service quality.
In a word, traffic classification is one of the important technologies in QoS. It can classify messages according to their characteristics and requirements, and adopt different processing methods for different types of messages to achieve better service quality.
Other applications of traffic classification in QoS
1. Traffic supervision: Traffic classification can identify and distinguish different types of messages, which enables network administrators to handle different types of messages in different ways. For example, if the traffic of users or applications exceeds their quota, traffic classification can mark these traffic as high priority for shaping or discarding, thus ensuring the fair use of network resources.
2. traffic shaping: Traffic classification can put messages with different priorities into different queues for inter-queue shaping. This helps to balance network load, prevent network congestion and improve network performance.
3. Traffic scheduling: Traffic classification can put different types of messages into different queues for scheduling between queues. This is helpful to optimize the utilization of network resources and improve network performance.
4. Traffic discarding: If the network resources are insufficient, traffic classification can mark some packets as low-priority or non-critical services and discard them. This can ensure the normal operation of high-priority or critical services.
