Research on Software Aging Modeling and Software Rejuvenation

Software aging modeling prediction and software rejuvenation of Linux network server are studied.The momentum term and simulated annealing are added in the BP neural network to improve the convergence speed and overcome the local minimum value,by which the software aging is modeled and predicted.Meanwhile,a kind of software rejuvenation technique enhancing the reliability and usability of software system is put forward.Study results indicate that the method decreases the software disable rate and the unavailable time.
