Embodiment Construction

[0038] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a method for establishing a tunnel, by enabling the network device to obtain the IP address of the network device where the destination device requested by the user is located, and establishing a tunnel with the obtained IP address as the purpose The address tunnel can realize the dynamic construction of the tunnel, avoiding the configuration of the tunnel on the network device, and can meet the needs of different users to use the tunnel technology to transmit messages.

[0039] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Embodiment 1 of the present invention provides a method for establishing a tunnel, which is applied to a VPN (Virtual Private Network, virtual private network) authenticated by an authentication server, such as figure 1 As shown, the tunnel establishment method provided in ...

Abstract

The invention discloses a tunnel building method and network equipment. The tunnel building method comprises the following steps: the IP address of first network equipment is obtained by the network equipment according to the address information of the first network equipment and sent by an authentication server, wherein the first network equipment is network equipment where destination end equipment with which the first network equipment is asked to be connected by a user is located; the IP address of the first network equipment serves as the destination address of the network equipment, a tunnel between the network equipment and the first network equipment is built, and the user and the tunnel are bonded so that the user can access the destination end equipment based on the tunnel. According to the tunnel building method and the network equipment, the network equipment can obtain the IP address of the network equipment where the destination end equipment that the user asks to access is located to build the tunnel used for message transmission for the user, the IP address of the network equipment where the destination end equipment is located does not need to be configured on corresponding network equipment manually when the tunnel is built, the complexity of manual configuration is reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a tunnel establishment method and network equipment. Background technique [0002] Tunnel technology is an encapsulation technology that can encapsulate data packets of other network protocols in its own packets, and then transmit them on the network. The path through which encapsulated data packets are transmitted in the network is called a tunnel. A tunnel is a virtual point-to-point connection, and both ends of the tunnel need to encapsulate and decapsulate data packets. Tunnel technology refers to the whole process including data encapsulation, transmission and decapsulation. [0003] At present, tunnels are usually established manually. Before establishing a tunnel, the destination address of the tunnel needs to be manually set on the network device. In this way, the network device can establish a link between the network device and the destination address b...
