Problems solved by technology

[0007] The purpose of the present invention is to provide a method that can quickly handle VPN device failures, so as to solve the problem in the prior art that when a VPN device fails, it takes a certain amount of time to renegotiate and establish a tunnel, which in turn leads to network interruption during this period of time. question

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The present invention proposes a VPN device fault handling method, such as figure 1 As shown, the method includes the following steps:

[0023] S1. Setting a certain network device in the VPN as a VPN primary device, and configuring a VPN backup device for the VPN primary device;

[0024] S2. The VPN server negotiates with the VPN peer device and establishes a tunnel, and at the same time transmits the negotiation data to the VPN master device, so that the VPN master device and the VPN peer device perform encrypted packet transmission;

[0025] S3. When it is detected that the VPN active device fails, the VPN standby device sends a device switching request message to the VPN server, and the VPN server transmits the negotiation data and the sequence number of the current message to The VPN backup ...

Abstract

The invention discloses a method for processing VPN equipment faults. The method includes: setting a certain network device as the VPN main device, and configuring a VPN backup device for it; the VPN server negotiates with the VPN peer device and establishes a tunnel, and simultaneously transmits the negotiation data to the VPN main device, Encrypt message transmission between the VPN master device and the VPN peer device; when the VPN master device fails, the VPN backup device sends a device switching request message to the VPN server, and the VPN server will negotiate the data and the serial number of the current message It is transmitted to the VPN backup device, and then the VPN backup device and the VPN peer device perform encrypted message transmission. The technical solution proposed by the invention can quickly perform tunnel switching when the main VPN device fails, thereby reducing time loss and flow loss caused by network device failure.

Description

technical field [0001] The invention relates to a virtual private network (VPN) technology, in particular to a method for troubleshooting VPN equipment. Background technique [0002] VPN (Virtual Private Network, virtual private network) refers to the technology of establishing a private network on a public network. VPN essentially uses encryption technology to encapsulate a data communication tunnel on the public network. [0003] IPSec is a tunneling protocol working at the network layer of the OSI model, and it is also the most commonly used tunneling protocol in VPN. AH (AuthenticationHeader, authentication header) and ESP (EncapsulationSecurityPayload, encapsulation security body) are the two most basic IPSec security protocols. Among them, the AH protocol is used to provide access control, connectionless integrity, data source verification and anti-replay services; the ESP protocol adds two security services, confidentiality and limited communication flow confidentia...
