Communication system, communication apparatus, and method of communication

A communication apparatus comprising:

• a memory;
• a plurality of ports;
• and
• a processor coupled to the memory and to the plurality of ports,
• wherein the communication apparatus is configured to communicate with a terminal apparatus, the communication apparatus is configured to communicate with a plurality of communication apparatus including the first information processing apparatus through respective ports, the communication apparatus is configured to communicate with a first information processing apparatus through a first port of the plurality of ports,
• wherein the processor is configured to:
• generate, when receiving a keyword related to a content which is included in the respective communication apparatuses via the respective ports, correspondence information including a combination of the keyword and the respective ports indicating a transfer destination port of a search request from the terminal apparatus;
• store the correspondence information in the memory;
• receive, from the first information apparatus, a first keyword related to the first content stored in the first information processing apparatus;
• generate, as the correspondence information, a first combination between the first keyword and the first port to which the first information processing apparatus is coupled,
• receive, from the terminal apparatus, a first search request that includes a search word,
• search, in the search word, the first keyword of the correspondence information stored in the memory,
• when the search word includes the first keyword, specify, as the transfer destination port of the first search request from the terminal apparatus, the first port corresponding to the first keyword from the plurality of ports based on the first combination,
• send, through the first port, the first search request to the first information processing apparatus,
• acquire, through the first port, the first content from the first information processing apparatus, and
• send the first content to the terminal apparatus.

A method of communication using a terminal apparatus, a first information processing apparatus storing a first content and a communication apparatus including a plurality of ports, the communication apparatus being configured to communicate with a plurality of communication apparatus including the first information processing apparatus through respective ports, the communication apparatus being configured to communicate with the terminal apparatus, the communication apparatus being configured to communicate with the first information processing apparatus through a first port of the plurality of ports, the method comprising:

• generating, by the communication apparatus, when receiving a keyword related to a content which is included in the respective communication apparatuses via the respective ports, correspondence information including a combination of the keyword and the respective ports indicating a transfer destination port of a search request from the terminal apparatus;
• storing, by the communication apparatus, the correspondence information in a memory in the communication apparatus;
• receiving, by the communication apparatus, from the first information processing apparatus, a first keyword related to the first content stored in the first information processing apparatus;
• generating, by the communication apparatus, as the correspondence information, a first combination between the first keyword and the first port to which the first information processing apparatus is coupled;
• receiving, by the communication apparatus, from the terminal apparatus, a first search request that includes a search word;
• searching, in the search word, the first keyword of the correspondence information stored in the memory,
• when the search word includes the first keyword, specifying, by the communication apparatus, as the transfer destination port of the first search request from the terminal apparatus, the first port corresponding to the first keyword from the plurality of ports based on the first combination;
• sending, by the communication apparatus, through the first port, the first search request to the first information processing apparatus;
• acquiring, by the communication apparatus, through the first port, the first content from the first information processing apparatus;
• and
• sending, by the communication apparatus, the first content to the terminal apparatus.
