摘要
当今许多安全领域的应用要求关键任务系统能提供不间断的服务,并能对运行环境的变化做出积极有效的适应性反应,能否实现对系统软件的动态更新或软件组件的动态替换就成为问题解决的关键。对此,提出了采用任务热插拔技术来实现关键任务系统任务组件的动态替换,探讨了任务组件替换的主要问题及关键实现技术,进行了初步的实验研究并达到了预期的实验效果。
Currently,mission-critical systems are needed to provide uninterrupted services,and to effectively respond to the varying environment in many security fields.Whether dynamic update of the system software or the dynamic replacement of the software components can be realized or not becomes the key point of the problem.So the mission hot-swapping technology is proposed to realize the dynamic replacement of the mission-critical systems,the main problems and key technologies of the mission components replacement are discussed,and elementary experiment is done to validate that the method has gained the prospective effect.
