Voting is a traditional mechanism used for maintaining the consistency of replicated data in


distributed systems. A significant problem in protocols that use voting is the size of the


quorum needed on each access to the replicated data. In this paper, we propose replica


control protocols where the synchronization cost is reduced by exploiting the structural


information of the underlying system. We also propose a novel logical structure for


managing replicated data, by imposing a logical wheel structure on the set of copies of an


object. The logical structure ensures minimum read quorum size of one, by reading one


copy of an object while guaranteeing fault-tolerance of write operations.
