<p><P>PROBLEM TO BE SOLVED: To provide a communication network system for reducing the amount of data, a communication apparatus, a communication method in the communication network system, and also to provide a communication network system etc. allowing interconnection. <P>SOLUTION: In the communication network system, frames are exchanged between a first and a second communication apparatus via a relay device. The first communication apparatus is equipped with: a transmission part for transmitting to the second communication apparatus a first frame or a second frame from which information concerning the communication apparatus outside the communication network system is deleted with respect to the first frame; and a reception part for receiving the first and second frames from the second communication apparatus. The transmission part performs the capsuling of the frame for an external network outside the communication network system with the use of the frame for an internal network inside the communication network system, so as to transmit the capsuled first or second frames. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
