摘要： PROBLEM TO BE SOLVED: To use line capacity effectively and improve a response time while one failure does not affect the whole system, by dispersing data request management without using a centralized control. SOLUTION: A server A1, and a server B2 transmit autonomously data request packets 121, 122 to a controller 11 in the same IP multicast group 4, and thereby the data is requested autonomously while centralized control is not performed. Through the data request packets 121, 122 including T. O. time 111 and 112, the server A1 and the server B2 communicate with the controller 11. In the controller 11, it is compared with the time-out period managed in itself, every time it is requested; and the set value of the time-out period is renewed. With respect to the same data transmission request from the server A1, B2, the transmission is performed effectively through IP multicast communication 33. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce time and effort to change a memory area for use in a transfer memory system. SOLUTION: A node 1 used for the transfer memory system comprises an area management table 112, indicating for each area on a transfer memory 111, identification information of a node 1 securing the area. Upon the receipt, from a different node 1, secured area information, indicating the area secured by the different node 1 and changed area information, indicating the area to be additionally requested, the node 1 updates the area management table 112, based on the received information. Moreover, when there is an instruction for adding a secured area issued, the node 1 ascertains, by referring to the area management table 112, that the area to add as instructed is not secured by a different node 1; and then transmits to different nodes 1 of the changed area information, indicating the area to add as instructed and the secured area information on the area secured by the node itself on the area management table 112.

摘要： PROBLEM TO BE SOLVED: To dynamically change the time-out time of a second time during system execution in a monitoring device using a watchdog timer in two stages. SOLUTION: This monitoring device is provided with the watchdog timer 20 capable of arbitrarily setting the time until time-out, a processor 10 for executing a task, a register 30 for storing the time-out time set to the watchdog timer 20 and a flip-flop 40 for storing the number of times of time-out generation. The processor 10 cyclically executes the task for system control and it is monitored in the watchdog timer 20. In the case that a time-out error is generated, a time-out processing task 13 is executed and the time-out processing task 13 is also monitored in the watchdog timer 20. Monitoring time is changed by the completion state of the cyclical task. When the time-out processing task 13 generates the time-out error, system stoppage is requested.
