Abstract
A redundant network IP smart failover method and system based on a redundant computer. Each computer in any computer group comprises an IP address switching module, a network status detecting module, and a peer fault detecting module. The IP address switching module is configured to smoothly switch an IP address in the redundant network. The peer fault detecting module is configured to mutually exclusively and stably acquire operation statuses of peer computers and quickly obtain a correct redundant network IP when necessary. The network status detecting module is configured to determine statuses of local and remote networks to facilitate the IP address switching module to smartly switch the IP address. Configuring a network status detecting module and a peer fault detecting module to aid the IP address switching module to allocate IP addresses more smartly can significantly improve reliability of the redundant network and effectively reduce IP conflicts during the redundant network failover process.
