A node (1) establishes the location ID of a transfer destination as a search key when an object request message includes the location ID of the transfer destination, searches its own location ID transfer table (13), and transfers the object request message to the node (1) in the next hop which is obtained in this manner. When an object request message does not include the location ID of the transfer destination, the node (1) establishes the object ID included in the object request message as a search key, searches its own object ID transfer table (11), and transfers the object request message to the node (1) in the next hop from the search results. |
