Embodiment Construction

[0028] The embodiment of the present invention provides a method for establishing a network tunnel, a data transmission method, a communication system and related equipment, which are used to improve the performance of data transmission in a VPN.

[0029] see figure 1 , an embodiment of the method for establishing a network tunnel in the embodiment of the present invention includes:

[0030] 101. The first VPN node initiates a query request to a corresponding VPN gateway according to a locally preset VPN gateway address.

[0031] In this embodiment, when the first VPN node expects to communicate with the second VPN node, the node identifier of the second VPN node may be determined. The specific node identifier may be a node name or a node number, which is not limited herein.

[0032] The first VPN node can request to establish a direct network tunnel with the second VPN node, then the first VPN node needs to know the registration information of the second VPN node, and then t...

Abstract

The embodiment of the invention discloses a network tunnel establishing method, a data transmission method, a communication system and relevant equipment, which is used for improving the data transmission performance of a VPN. The method of the embodiment of the invention comprises the following steps: a first virtual private network (VPN) node sends a search request to a corresponding VPN gateway according to a local preset VPN gateway address, and the search request carries a node identification of a second VPN node; the first VPN node receives the registration information of the second VPN node fed back by the VPN gateway, and the registration information of the second VPN node at least comprises the address information of the second VPN node; and the first VPN node establishes a direct access network tunnel with the second VPN node according to the registration information of the second VPN node. The embodiment of the invention also provides a data transmission method, a communication system and relevant equipment. The embodiment of the invention can effectively improve the data transmission performance of a VPN.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for establishing a network tunnel, a data transmission method, a communication system and related equipment. Background technique [0002] A virtual private network (VPN, Virtual Private Network) is a temporary, secure connection established through a public network (usually the Internet). Usually, a VPN is an extension of an enterprise's intranet, through which it can help remote users, company branches, business partners, and suppliers establish credible and secure connections with the company's intranet and ensure safe data transmission. [0003] The realization of VPN technology is usually based on network tunnels, connecting several existing private networks and computer equipment through the Internet to form a unified virtual private network. [0004] From the perspective of logical structure, the VPN of the prior art is a star-shaped network structure with ...
