According to one aspect, a communication apparatus is provided which is on a LAN and coupled to a server via an external network involving a NAT traversal with a router of the LAN. The communication apparatus is configured to determine a configuration of the router of the LAN; and request the server to transmit a NAT update request packet to the router, which is registered in the server and performs the NAT traversal, when it is determined that the configuration of the router of the LAN is in two or more stages.

Communication apparatus, server, communication system, and communication method

A wireless communication system includes: a first wireless communication terminal to register an external device, wherein a subscriber information management device transmits a location of the external device to the first wireless communication terminal based on a search result of the external device based on a search request for the external device, the search request being transmitted from the subscriber information management device to a second wireless communication terminal within a search target area, the second wireless communication terminal being identified by the subscriber information management device based on registration information including certain information and location information of the external device.

Wireless communication system, wireless communication terminal, and subscriber information management device

A communication terminal which sends a frame to another terminal when performing a load distribution process using load distribution information appended to a frame that is sent/received between terminals within a communication network, the communication terminal comprises: a communication control part that specifies a sending port used for sending the frame; a load distribution information originating side designation part that stores load distribution structuring information, which is to be appended to the frame and used for generating the load distribution information, by relating to a sending port; a load distribution information transfer processing part that, when the sending port is specified, retrieves the load distribution structuring information corresponding to the determined sending port from the load distribution information originating side designation part; a send information setting part that structures the frame based on the load distribution structuring information and a load distribution information setting format; and a send frame processing part that sends out the structured frame from the sending port.
