Abstract: Survivable schedule algorithm is one of the important aspects of survivability study. This paper introduces stochastic mechanism to the server cluster systems, which makes it uncertain for the services rotating among the servers, so as to promote the difficulty for the intruders penetrate the systems, and enhances the survivability. It introduces the layers of survivability study, illustrates the function of the survivable schedule algorithm in the study, and analyzes the advantages and disadvantages of the exist algorithms; promotes a pseudo-random autonomous algorithm for service survivability schedule. The performance of the algorithm is investigated.

Key words: survivability, server cluster, pseudo-random sequence, schedule algorithm
