Abstract

The invention provides a message transmission method, device and system. The method comprises the steps of sending a first message to a slave VPN (Virtual Private Network) server by employing a source address after the first message from an export device is received, thereby enabling the slave VPN server to unpack the first message; sending a second message to a management server by employing a destination address after the second message from the slave VPN server is received, thereby enabling the management server to carry out service processing on the second message; sending a third message to the slave VPN server by employing the destination address after the third message from the management server is received, thereby enabling the slave VPN server to package the third message; and sending a fourth message to the export device by employing the destination address after the fourth message from the slave VPN server is received, thereby enabling the export device to forward the fourth message to a video device. Through adoption of the technical scheme of the method, the device and the system, the processing performance of each VPN server can be improved, and the integrated performance of a video monitoring system can be improved.

Description

technical field [0001] The present invention relates to the technical field of network management, in particular to a message transmission method, device and system. Background technique [0002] VPN (Virtual Private Network, Virtual Private Network) is a remote access technology that can use public networks to set up private networks so that users can access intranet resources. For example, if a VPN server is set up on the intranet of the enterprise, employees from other places can connect to the VPN server through the Internet after connecting to the Internet (that is, the public network) locally, and then enter the intranet of the enterprise through the VPN server. In this way, it can be considered that data is transmitted securely on a dedicated data link, just like a dedicated network has been set up, but in fact the VPN uses a public link on the Internet. [0003] Such as figure 1 As shown, it is a schematic diagram of a network for deploying a VPN server in a video ...
