Network interconnection apparatus, network interconnection method, name resolution apparatus and computer program
First Claim
1. A network interconnection apparatus for interconnecting an external network with an internal network, said network interconnection apparatus comprising:
- first communication means for communicating on said external network;
second communication means for communicating on said internal network;
internal network management means for obtaining a configuration in said internal network and managing correspondence relations among a unique address of each terminal on said internal network, a terminal name easily identifiable by a user, and a private network address assigned in said internal network;
start request reception means for receiving by proxy a start request to a terminal on said internal network via said external network; and
start request transfer means for identifying said terminal of requested destination of said start request received by said start request reception means based on said correspondence relations and transferring said start request to said terminal of said requested destination via said internal network.

Abstract
A power source of a LAN terminal at a home such as home server is turned on from the outside the home via the Internet. A home gateway apparatus receives such a start request by proxy and transmits a start instruction packet to corresponding equipment on the home LAN. Although there is a case where the protocols of an external network and the home LAN are different from each other, the home gateway apparatus performs a protocol conversion process for assimilating discrepancy between the protocols. Moreover, on the home LAN, the start instructionpacket to the corresponding equipment maybe issued by utilizing a magic packet technique.

25. A computer program described in a computer readable format in order to execute a process for interconnecting an external network and an internal network on a computer system, said computer program comprising:
-
an internal network management step of obtaining a configuration in the internal network to manage correspondence relations among a unique address of each terminal on the internal network, terminal names to be easily identified by a user, and private network addresses assigned in the network;
a start request reception step of receiving start requests to the terminals on the internal network via the external network by proxy; and
a start request transfer step of identifying the terminals of requested destinations of the start requests received at the start request reception step on a basis of the correspondence relations to transfer the start requests to the terminals of the requested destinations via the internal network.
