Integrated overload control for distributed real-time systems

Abstract From the Canadian patent

A method of responding to overload in a real time control system. Overload is measured through the use of a control parameter such as the occupancy of a control, processor or the number of entries in a queue of a module of the system. The overload indication is reduced to one of a plurality of levels. The levels corresponding to a longer term more serious overload are based on control parameter, measurements over a longer period of time than the less serious short term overload, levels. With autonomous control each module of the system determines its own overload level and performs overload control actions corresponding to that level. In, integrated system overload control a centralized …
