摘要：

针对现有的面向资源的故障定位方法无法直接应用于资源与任务耦合紧密的网络空间环境的问题,文章提出了一种面向任务的网络空间故障定位模型。首先,引入超图理论构建网络空间任务资源模型,刻画网络空间环境中任务与资源的复杂交互关系,为研究故障定位问题奠定了模型基础;其次,进一步分析任务运行过程中的故障关联,根据故障在网络空间中的传播逻辑,推导出了资源故障影响任务运行能力的函数;在此基础上,提出任务故障分段定位算法,实现从任务故障到作业故障的定位,提出作业故障迭代定位和协同定位方法,实现从作业故障到资源故障的定位,从而建立了面向任务的网络空间故障定位模型。最后,通过典型故障定位案例验证了模型的有效性。

Abstract:

Due to the fact that existing resource-oriented fault location methods were not suitable in cyberspace, where resources and missions were coupled tightly, a mission-oriented fault location model was presented. Firstly, with the application of hypergraph theory, a mission-resource model was built to portray complex relationships between resources and missions. This model establishedthe foundation for the further study of fault location problem in cyberspace. Furthermore, according to the logic of the propagation of fault in cyberspace, a function describing the effect of resource fault on mission performance was derived. Then we proposeda segment location algorithm to locate task faults based on mission faults; and then proposed an iteration method and a collaboration method to locate resource faults based on task faults. Based on these, we constructed the mission-oriented fault location model in cyberspace. Finally, we verify the effectiveness of the presented model through analyzing atypical fault location case in the military field.

Key words: cyberspace, hypergraph, fault association, fault location
