REDUNDANT COMPUTER-BASED REDUNDANT NETWORK IP INTELLIGENT SWITCHING METHOD AND SYSTEM

WIPO Patent Application WO/2021/169311

A1

The present invention relates to a redundant computer-based redundant network IP intelligent switching method and system. Each computer in any computer group respectively comprises an IP address switching module, a network state detection module, and a paired system fault detection module, wherein one can smoothly switch between IP addresses in a redundant network by means of the IP address switching module; the mutually exclusive and steady-state acquisition of a paired system working state is performed by means of the paired system fault detection module, and a correct redundant network IP is quickly obtained when necessary; and by means of the network state detection module, a local network state and a remote network state are determined to assist the IP address switching module in intelligently switching the IP address. In the present invention, the network state detection module and the paired system fault detection module are added to assist the IP address switching module in allocating IP addresses more intelligently, which may greatly improve the reliability of the redundant network and effectively reduce the number of IP conflict problems during the redundant network switching process.
