PROCESS FOR AUTOMATIC EVENT REPORT REALIGNMENT IN A MANAGEMENT SYSTEM AND RELATED SYSTEM

摘要

A process is described for automatic realignment of the state information transferred from a managed subsystem to one or more managers by the event report technique. In accordance with this process the events generated by changes in the state variables are written in a memory of the events which is managed as a circular queue by means of pointers. Multiple independent reading processes, each related to a respective manager, read the queue non-deterministically and asynchronously in relation to the writing. During each writing in the queue there can occur information loss, and hence misalignment, if the writings proceed at a cadence higher than that of the readings. If this happens the managed subsystem takes notice of it and acquires a copy of its own present state, which it sends to those managers for which the queue is in overflow and at the end it also sends the events detected in the meantime.
