The reliability of regeneration-based replica control protocols

Several strategies for replica maintenance are considered, and the benefits of each are analyzed. Formulas describing the reliability of the replicated data object are presented, and closed-form solutions are given for the tractable cases. Numerical solutions, validated by simulation results, are used to analyze the tradeoffs between reliability and storage cost. With estimates of the mean times to site failure and repair in a given system, the numerical techniques presented can be applied to predict the fewest number of replicas required to provide the desired level of reliability.<>
