<p><P>PROBLEM TO BE SOLVED: To shorten the total communication time needed for message sharing in a ring by increasing transfer efficiency of messages. <P>SOLUTION: A plurality of nodes are constituted in a ring shape and a communication program multicasts a message, transmitted from an arbitrary node as an origin, in the ring by transferring the message forward and backward in the ring. When the communication program transmits a message from its node as an origin, the message is transmitted forward and backward. When a message transmitted from one origin is received in the forward or backward direction, it is decided whether the message is already received or not and transfer of the message is performed according to the decision result. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
