With the development of the Internet, the scale of the network is constantly expanding, the types of services are gradually increasing, the heterogeneity of the network is becoming stronger and stronger, value-added services are constantly emerging, and the importance of real-time monitoring of network performance is also being strengthened. Traffic engineering and traffic engineering systems are closely linked with real-time monitoring of network performance. Traffic engineering can be defined as a collection of technologies that allow service providers to provide network services based on different levels of service quality and maximize the use of network resources. The main concepts of network performance monitoring using IP network traffic engineering and traffic engineering system are mainly discussed. The architecture of network performance real-time monitoring system based on traffic engineering is given. The module of network performance real-time monitoring system is expounded. The development of network performance real-time monitoring is described
