摘　　要：服务连续性和自适应性是许多关键任务系统的客观要求,为此提出采用任务热插拔的方法予以实现。介绍任务热插拔的基本思想,分析实现任务组件插入和替换的关键技术,总结了任务热插拔的技术实现路线,并开展了初步的实验研究。结果表明,该方法实现了任务组件的动态替换,可用于提高关键任务系统的可用性及适应性。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.
