PROBLEM TO BE SOLVED: To surely detect the reception of a message related to the message originated in the past by a message processor. SOLUTION: This message processor 100-1 adds a unique origination identifier for identifying the origination to the message at the time of originating the message, originates it to the message processor (for instance, the message processor 100-2) of a transmission destination and registers the origination identifier and the originated message in a storage part 2 in correspondence. In the case of returning a response message to the message processor, the message processor 100-2 adds the origination identifier added to the received message to the response message. The message processor 100-2 which receives the response message judges that it is the message related to the message originated in the past since the same identifier as the origination identifier registered in the storage part 2 is added to the received response message. |
