High-reliability network communication system and method

Abstract

The invention provides a high-reliability network communication system and method, and the system comprises a first intranet and a second intranet, the first intranet is provided with a first server and first communication equipment, and the second intranet is provided with second communication equipment and a second server, wherein the first communication equipment is virtualized with a first main gateway and a first standby gateway; the second communication equipment is virtualized with a second main gateway and a second standby gateway; a first version program is installed in the first maingateway and the second main gateway, and network connection is carried out through the first version program to construct a main communication link; a second version program is installed in the firststandby gateway and the second standby gateway, and network connection is performed through the second version program to construct a standby communication link; and the first communication device and the second communication device default to enable the main communication link to perform network communication, and when the main communication link is abnormal, the main communication link is switched to the standby communication link. According to the invention, the reliability of inter-network communication can be enhanced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a highly reliable network communication system and method. Background technique [0002] At present, large companies at home and abroad usually have one headquarters and multiple branches, and the multiple branches may be distributed in different regions. In order to realize data communication between branches in different regions and the headquarters, IPSec is usually used. Establish a virtual private network (Virtual Private Network, VPN) channel between the servers through the VPN gateway to realize the network interconnection between the branch office and the headquarters, and then realize the intercommunication of data. [0003] There are corresponding programs installed in the VPN gateway. Once the program is old, outdated or insecure, the program needs to be upgraded. However, during the upgrade process, the original program needs to be uninstalled before the...

AI Technical Summary

Problems solved by technology

[0003] There are corresponding programs installed in the VPN gateway. Once the program is old, outdated or insecure, the program needs to be upgraded. However, during the upgrade process, the original program needs to be uninstalled before the upgraded program can be installed. Often the upgraded program is not fully compatible with the needs of the actual environment. Once the upgraded program has problems and cannot run normally, the original program has also been uninstalled, resulting in interruption of the network connection and poor reliability of the network connection.

In addition, some intermediate data generated during the running of the original version of the program may not be recognized by the upgraded program. Once the original program is uninstalled, it may cause network data packet loss and other problems
