Abstract
A gateway apparatus connected to another different network. The gateway apparatus includes: extraction unit that extracts first information set in a first packet(s) that has been received from a relay apparatus relaying a packet(s) between the gateway apparatus and a terminal or from a node arranged in the different network; setting unit that sets, based on the first information, second information in a second packet(s) in a protocol(s) in a layer(s) different from a layer(s) of a protocol(s) of the first packet(s); and forwarding unit that forwards the second packet(s) in which the second information is set to the node or to the relay apparatus.
Claims20
A gateway apparatus, connected to another different network, the gateway apparatus, comprising:
- an extraction unit that extracts, from a first packet(s), first information set in the first packet(s) that has been received from a relay apparatus relaying a packet(s) between the gateway apparatus and a terminal or from a node arranged in the different network;
- a setting unit that sets, based on the first information, second information in a second packet(s) in a protocol(s) in a layer(s) different from a layer(s) of a protocol(s) of the first packet(s);
- and
- a forwarding unit that forwards the second packet(s) in which the second information is set to the node or to the relay apparatus.
A method of controlling a gateway apparatus connected to another different network, the method, comprising:
- steps of:
- extracting first information set in a first packet(s) that has been received from a relay apparatus relaying a packet(s) between the gateway apparatus and a terminal or from a node arranged in the different network;
- setting, based on the first information, second information in a second packet(s) in a protocol(s) in a layer(s) different from a layer(s) of a protocol(s) of the first packet(s);
- and
- forwarding the second packet(s) in which the second information is set to the node or to the relay apparatus.
A program, recorded on a computer readable non-transient storage medium, the program causing a computer in a gateway apparatus connected to another different network, to perform processing of:
- extracting first information set in a first packet(s) that has been received from a relay apparatus relaying a packet(s) between the gateway apparatus and a terminal or from a node arranged in the different network;
- setting, based on the first information, second information in a second packet(s) in a protocol(s) in a layer(s) different from a layer(s) of a protocol(s) of the first packet(s);
- and
- forwarding the second packet(s) in which the second information is set to the node or to the relay apparatus.
