✦ Synopsis

This paper discusses the problem of placing data replicas in a ring network to maximize data availability. For read-anyÂwrite-all protocol, we prove that the equally spacing placement is optimal for read-dominant systems, while the grouping placement is optimal for write-dominant systems. For majorityvoting protocol, we give some necessary conditions for optimal placements.
