Xie Chang · Jisuanji gongcheng · 2003
There are special background and demand for guarantee of reliability in the realtime TTC computer application system with function distributed architecture. Based on the comprehensive research of current guarantee of reliability technologies, this paper puts forward a guarantee project of reliability with distributed implementation and centralized control. It uses online dual backup or multiserver redundance plan in all nodes, which meets realtime demand and process protected by hardware switching. The actual application proved that the plan is simple to implement and better to apply to the realtime computer application system in the spaceflight TTC centers.
