Abstract: Service continuity and self-adaptive capability are the objective requests for many mission-critical systems, so mission hot-swapping technology is proposed. The basic principle of mission hot-swapping is introduced, and key technologies to implement interposition and replacement of the mission components are analyzed. Technical routes of mission hot-swapping are summarized and elementary experimental research is carried out. The experimental results show that the method has implemented the dynamic replacement of the mission components, and it can be used to improve the availability and adaptability of the mission-critical systems.

Key words: mission hot-swapping, running monitoring, dynamic loading, quiescent state establishment, dynamic interposition
