Abstract
In a method and a device for notifying a server failure recovery which notify a failure recovery of a server or the like to a client, a server failure detector detects a client having tried but failed to access a server due to a failure, a server recovery detector detects a failure recovery, and a server recovery notifier gives a failure recovery notification to the client having failed to access. Also, the server failure recovery notification device is mounted on a router. The server failure detector detects the client having failed to access based on a destination unreachable message of an ICMP of the router, or detects the client having failed to access by determining the failure is being occurred in the server, in the absence of a reply IP packet to the IP packet addressed to the server from the client.
