Abstract
Abstract With the development of the network era, ISP have become more than one. Users can choose ISP according to personal preference when buying broadband, to provide users with the right to choose. However, with the improvement of network speed and bandwidth, people still feel the network congestion during peak hours. In this paper, users can choose different ISPs dynamically based on network quality monitoring. In this paper, the HTTP protocol of the application layer is used to accurately measure the real Internet situation of users, and the PC is used to actively send data to two network links at the same time, and finally the feedback parameter information can be obtained. According to this protocol, the real loading time of data can be accurately measured and the optimal ISP link can be selected. Then, a one-to-one relationship between the client address and different ISPs is established, and this relationship is saved in the routing table. Users will dynamically choose different ISPs by using the network address translation.

Summary
Network measurement is obtaining the parameters and performance of the network through quantitative measurement. The main parameters of network measurement include congestion, delay, bandwidth, packet loss rate, throughput response speed and other application quality of service. Measurements can be divided into different types. According to the network level involved in the measurement, it can be divided into network layer measurement and application layer measurement. The measurement method of this paper uses the means of application layer protocol. Because there are bottlenecks in the network switching interfaces between different ISPs and the use of various filtering technologies, the quality of the network layer is not equal to the quality of the application layer, so choosing application layer measurement can more accurately grasp the network conditions of applications. The application layer measurement method chosen in this paper can be divided into active measurement, probe measurement and proxy measurement according to the difference between measurers and participants [2]
