Research on Mission Hot-Swapping and Dynamic Replacement Mechanism of Mission Component

It´s urgently necessary for many mission-critical systems with high availability to implement online updating, fault recovery and environmental adaptability of software. Therefore, the idea of mission hot-swapping is proposed, in which, related problems and key technologies of mission component´s dynamic replacement is analyzed. A dynamic replacement mechanism of mission component based on interceptor and component container is put forward. The research results show that the dynamic replacement of mission component is feasible and the idea of mission hot- swapping is correct.
