Abstract

The resilience of a distributed system refers to the ability of the system to recover its own behavior and continue to complete its task after suffering from external influence or failure. This paper presents a resilience analysis method based on complex network modeling method to solve the impact of different attack strategies and recovery strategies. Firstly, the complex network model of the system based on the functions of the distributed system, on the basis of the network information data, the anti-destructiveness and recoverable indexes from the process and results are analyzed by analyzing the influence of different strategies on the system resilience. Based on the comprehensive consideration of different attack strategies and recovery strategies, the topology combines the state performance to obtain the resilience element parameters and complete the resilience analysis of the distributed system. The case simulation results show that compared with the existing research, the proposed method models the distributed network based on the correlativity of various components in the cluster system, obtains the complex network model, and then calculates the resilience comprehensive index of the distributed system based on the resilience comprehensive analysis to improve the recovery ability of the system.
