Network data traffic diversion method based on transparent deployment, and traffic diversion apparatus and system

Abstract

The invention discloses a network data traffic diversion method based on a transparent deployment, and a traffic diversion apparatus and system. The method comprises the steps of obtaining a connection state information; when the state information is first state information, sending a channel establishment request to a virtual private network server, such that the virtual private network server sends a channel establishment response according to the channel establishment request; and receiving the channel establishment response, establishing a virtual private network channel with the virtual private network server according to the channel establishment response, and transferring network data uploaded by a network surfing device to the virtual private network server via the virtual privatenetwork channel. According to the network data traffic diversion method based on the transparent deployment, and the traffic diversion apparatus and system, a traffic diversion device is arranged at an entrance of a gateway device, and the virtual private network channel is established with the virtual private network server via the traffic diversion device, so under a condition in which an original network topological structure is unchanged, the network data are forwarded to the virtual private network server via the network channel.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a traffic diversion method, a traffic diversion device and a system based on transparently deployed network data. Background technique [0002] A virtual private network (Virtual Private Network, VPN) belongs to a remote access technology, and a private network is set up by using a public network. For example, when an employee of a company travels to other places and accesses the server resources of the enterprise intranet, this kind of access is called remote access. [0003] In a traditional enterprise network configuration, to perform remote access, the traditional method is to lease a digital data network (Digital Data Network, DDN) dedicated line or frame relay. Such a communication scheme will inevitably lead to high network communication and maintenance costs. For mobile users and remote personal users, they generally enter the enterprise's local are...
