Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] figure 2 It is a schematic flow chart of the present invention, and the whole system of the present invention is divided into two parts, the management plane and the data plane:
[0041] Management plane: used for the establishment of data plane and distribution of management configuration
[0042] Data plane: used to carry reverse data transmission
[0043] The transmission process of reverse penetration data in the present invention is as follows:
[0044] 1. The internal network device and the public network IP server establish a TCP connection through a private protocol, and open up the management plane channel;
[0045] 2. When reverse data penetration is required, the public network IP server notifies the intranet device to establish a PPTP tunnel through the management plane channel, that is, the data plane tunnel;
[0046] 3. Intranet device configu...
