Embodiment Construction

[0054] The following embodiments of the present invention provide a method, device and server for establishing a VPN tunnel.

[0055] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0056] see figure 1 , which is a schematic diagram of the VPN architecture applying the embodiment of the present invention:

[0057] figure 1 The server in can include multiple VMs, such as figure 1 exemplarily shows VM1 and VM2, and a virtual platform (Hypervisor) for unified management of VMs. The virtual platform is a meta-operating system in a virtual environment. Through the virtual platform, y...

Abstract

The embodiments of the invention disclose a VPN tunnel establishing method, device and server. The method comprises the following steps: the server is used to acquire a negotiation data packet transmitted between a first VM and a second VM; the first VM and the second VM are determined to be VMs born by the server according to the negotiation data packet; VPN tunnel common parameters are generated for the first VM and the second VM; and a shared tunnel descriptor SA is generated for the first VM and the second VM according to the VPN tunnel common parameters to complete the establishment of the VPN tunnel. By applying the embodiments of the invention, when a VPN tunnel is established between two VMs belonging to a same server, the server is used to generate the VPN tunnel common parameters for the two VMs, so the complexity for establishing the VPN tunnel can be reduced, the establishing speed of the VPN tunnel can be improved; and SAs do not need to be established for the two VMs separately, but a shared SA is established for the two VMs, so the memory consumption of the server can be reduced.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and server for establishing a virtual private network (Virtual Private Network, VPN for short) tunnel. Background technique [0002] VPN refers to the technology of establishing a private network on a public network. VPN supports the establishment of VPN tunnels between communication parties to encrypt the transmission process and improve transmission security. The two parties to establish a VPN tunnel can be a virtual machine (Virtual Machine, VM). VM refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. It can usually be installed on a physical server. Multiple VMs can be simulated, and multiple VMs can also be simulated on multiple physical servers. In the prior art of applying VPN, VPN tunnels may be established between VMs on the same physica...
