<p><P>PROBLEM TO BE SOLVED: To provide a method, a system, and a computer program product for executing high-reliability massaging by using a clock at a synchronized rate. <P>SOLUTION: One-time delivery at the maximum of a message is guaranteed and the clock at the synchronized rate is used for a sender and a destination. A time to live (TTL) value is allocated to each message. When a corresponding message timer based on the TTL value is terminated, state information is renewed on the sender's side and the state information is deleted on the destination side. When relevant state information is deleted, the sender can retransmit the state information to the destination of the message. When a memory is involuntarily lost on the side of the destination of the message, one-time delivery at the maximum is guaranteed by using a message processor instance ID. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
