The state of the system is determined by the state of the subsystem installed in the system, and the subsystem is DOWN, NORMAL, ABNORMAL depending on the state of the blocks selected as CRITICAL blocks among the belonging blocks. , RECOVERING, ISOLATING, ISOLATED, etc. DOWN indicates that all the critical blocks are finished, and NOMAL means that the processing of the job in which all the important blocks are in normal state is normal. Abnormal (ABNOMAL) indicates that any one of the critical blocks is in an abnormal execution state, and thus the processing of the task in charge may not be processed normally. The RECOVERING state represents the process by which the subsystem transitions to a normal state from a state such as shutdown / isolation / isolation. The ISOLATING state indicates that the intelligent network system is in the process of being isolated from the configuration according to the management of the redundant configuration when the subsystem is found to be inoperable.
