一种基于执行体的历史信息和异构性的置信目标快速构建算法

Fast Construction Algorithm for Confidence Targets Based on Historical Information and Heterogeneity of Executive Bodies

在拟态存储系统中,当元数据服务执行体产生调度换时,新上线的执行体需要从其他可信的执行体中获取元数据信息,进而实现各个异构执行体间元数据和执行状态的一致性。传统的置信度计算方法主要根据各执行体的历史裁决记录进行计算,不能满足系统运行初期突发调度的情况。提出一种基于执行体历史信息和异构性的置信目标快速构建算法,充分考虑了拟态防御动态异构冗余(Dynamic Heterogeneous Redundancy,DHR)基因,能够更快速并准确地构建执行体地置信度。

In the mimic storage system,when the metadata service executor is scheduled to change,the newly online executor needs to obtain metadata information from other trusted executors,thereby realizing the consistency of the data and status of each heterogeneous executor.However,the traditional confidence calculation method is mainly based on the historical ruling records of each executor,which cannot meet the situation of emergency scheduling in the early stage of system operation.This paper proposes a rapid construction algorithm for confidence targets based on historical information and heterogeneity of the executor,which fully considers the mimic defense dynamic heterogeneous redundancy(DHR)gene,and can construct the confidence level of the executor more quickly and accurately.
