And sending a tracking routing instruction by using the probe, detecting all interfaces which are distributed by the terminal to the currently used first network and are used for external access, and selecting a proper access interface from the interfaces as an external access interface when the terminal is connected with the first network.
The terminal allocates the external access interface to the first network mainly through a BGP protocol, and a proper access interface can be selected through different external access interface selection modes according to specific actual conditions. BGP, known in chinese AS border gateway protocol, is an inter-Autonomous System (AS) routing protocol running over TCP (transmission control protocol), and is the only routing protocol that can handle multiple connections between unrelated routing domains. Colloquially, China telecom, China Unicom, China Mobile and some large-scale private IDC operators with AS autonomous domains can realize multi-line interconnection through BGP protocol. For example, we go on a business to a city and can choose a variety of vehicles, such as highways (telecommunications), airplanes (communications), high-speed rails (moving), etc. BGP is more than an intelligent APP, can help users select the best traffic mode, and can automatically help users select the best traffic mode when an emergency occurs.

The BGP line industry also has the concept of "multi-line BGP" or "three-line BGP". "three-wire BGP" may be understood AS BGP interfacing with three basic operators (telecom, unicom, mobile) using their own public BGP AS-numbers, and "multi-wire BGP" may be understood AS BGP interfacing with three and more operators using their own public BGP AS-numbers. On the basis, the user of the BGP line broadcasts the IP address field of the user and uses the IP address of the user to access the Internet. The greatest characteristic of the BGP line is better access quality. Users in the three operator networks can access the same machine room resource at high speed nearby through the line of the operator, the problem of access quality reduction caused by cross-operator access does not exist, and therefore automatic cross-network access is achieved.
