A client device 6 may be connected to a network 2 through a private network and one of several connection servers 10, 11, 12, 13 associated with a router 1. In such a configuration a server 5 external to the private network cannot provide a complete routing address for data to be transmitted to the device 6, as it does not have visibility of the control processors 10, 11, 12, 13. To allow such connection to be made, when a connection request for a target client device 6 is transmitted from an external server 5 to the router 1, the router retrieves connection history of the target device 6 from each of the connection servers, and the router 1 then attempts communication with the client device 6 through the connection server 10 reporting the most recent connection. |
