In addition, PSTN (Public Switched Telephone Network) defines: public switched telephone networks, PSTN, provide an analog proprietary channel that is connected between channels via telephone exchanges. When two hosts or router devices need to be connected through PSTN, the network access side (i.e. subscriber loop side) at both ends must use a Modem (Modem) to perform analog/digital, digital/analog conversion of the signal. From the perspective of the OSI seven layer model, the PSTN can be seen as a simple extension of the physical layer, without providing services to users for flow control, error control, etc. Moreover, since PSTN is a circuit-switched approach, a path is built up until released, and its full bandwidth can only be used by devices at both ends of the path, even if no data needs to be transferred between them. Therefore, this circuit switched approach does not allow for full utilization of network bandwidth. Network interconnection is exemplified through the PSTN. The following is an example of a network interconnection that connects two local area networks via the PSTN. In the two local area networks, each router is provided with a serial port which is connected with a Modem, and the Modem is connected with PSTN, so that the interconnection of the two local area networks is realized.

Based on this understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art or in a part of the technical solution, in the form of a software product stored in a storage medium, comprising several instructions for causing a computer device (which may be a personal computer, a server, a network device, etc.) to perform all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a random access Memory (RAM, random Access Memory), a magnetic disk, or an optical disk, or other various media capable of storing program codes.
