With the rapid development of the Internet, the rapid development of various services, especially the rapid growth of multimedia services such as video and voice, the IP network has also changed from a single data network to a multi-service integrated digital network. The defect that traditional IP networks have no quality of service (QoS) guarantee has been revealed.
