Abstract
Disclosed herein is a contact destination information registration method employed in a network system including nodes and employing a distributed hash table. When registering contact destination information corresponding to a predetermined node address in the table, the node first performs a first operation of looking up a value associated with a key corresponding to the node address in the table, and, if no such value is found, registering provisional contact destination information in the table so as to be associated with the key and acquiring a registration time of the provisional information, but, if any such value is found, acquiring a registration time of that value, and then performs a second operation of registering the true contact destination information in the table, if the registration time of the value associated with the key in the table coincides with the registration time acquired by the first operation.
