<p><P>PROBLEM TO BE SOLVED: To change a communication confirmation channel of a tri-branch path for transmitting and receiving packets for communication confirmation between a transmitter and a receiver without going through a center device in a network communication confirmation channel switch method and a transmitter/receiver. <P>SOLUTION: The transmitter/receiver includes: a storage part 1-1 for storing network configuration information which includes channel information on communication confirmation of an area network divided into unit networks each including a tri-branch path, and communication state information; a communication confirmation part 1-3 for instructing packet transmission for communication confirmation; a communication state determination part 1-6 for receiving the packet for communication confirmation and evaluating an arrival result of the packet; and a communication switch setting part 1-7 which determines whether or not a communication confirmation channel of the tri-branch path is formed in the unit network and, when the communication confirmation channel of tri-branch path is not formed, determines a change destination of the communication confirmation channel so that the communication confirmation channel of the tri-branch path is formed inside each unit network based on the network configuration information and a communication confirmation channel switch principle. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
