METHOD FOR DOUBLE IP ADDRESS RECOVERY

摘要

A computer-implemented method, computer program product, and computer system for double IP address recovery. Double IP address is a situation of a same IP address for different hosts in a network, and the double IP address recovery resolves the double IP address. In the invention, the hosts exchanges rules and system state information. Each of the hosts determines its own action of the double IP address recovery based on the same rules and the system state information of the different hosts. Each of the hosts executes its own action, either to continue or to alter an IP address.

1. A computer-implemented method for double IP address recovery, wherein double IP address is a situation of a same IP address for both a first host and a second host, wherein the double IP address recovery resolves the double IP address, the method comprising steps implemented by the first host in a network:
generating a packet, the packet comprising rules of the double IP address recovery and system state information of the first host; broadcasting the packet to the second host; receiving a reply from the second host, the reply comprising system state information of the second host; determining whether the double IP address is detected; determining an action of the double IP address recovery on the first host, based on the rules of the double IP address recovery and the system state information of the first and second hosts, in response to determining that the double IP address is detected; and executing the action on the first host.
