Research on reliability model selection of computer network equipment based on AIC

Aiming at the problems of numerous failure distribution types of computer network equipment, the difficulty in selecting reliability models, and the difficulty in reliability evaluation, this paper proposes a method to select the reliability model of computer network equipment based on the information criterion by studying the failure rules of servers, switches, and computers in office LAN. On the basis of comparing the data fitting effect and error of equipment failure distribution type, the information criterion is introduced to analyze the fitting accuracy of reliability model, which improves the accuracy and effectiveness of model selection.
