In this case, however, it is difficult to manage both of them in an integrated manner. Therefore, it is not preferable from the viewpoint of performing efficient and accurate responses as a whole system.

The present invention has been made in view of such a problem, and comprehensively manages communication control and processing of abnormalities and the like, and has a processing capability related to communication processing control of communication resources during normal operation. It is an object of the present invention to provide a communication resource management device and a communication resource management method capable of promptly processing information on a communication error or a failure of the own device without lowering the information.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a central processing control means (central processing control task) comprehensively manages communication and management of abnormalities and the like, and a transaction directly related to the original communication processing control. A communication queue used for processing (message) and a communication queue used for processing a transaction for notifying a communication failure of a communication line or a transaction for notifying a failure of the own device are separated and dedicated for each processing. By managing the information, information on communication abnormalities and device failures is promptly and accurately provided to the central processing control means without lowering the processing capacity relating to communication processing control.
