Abstract
The read and write availabilities of replicated data managed by the regeneration algorithm, a replica control protocol based on file regeneration, are evaluated, and two regeneration protocols are presented that overcome some of its limitations. The first protocol combines regeneration and the available copy approach to improve availability of replicated data. The second combines regeneration and the dynamic voting approach to guarantee data consistency in the presence of network partitions while maintaining a high availability. Expressions for the availabilities of replicated data managed by both protocols are derived and found to improve significantly on the availability achieved using extant consistency protocols.<>
