Abstract
Replicated data is stored redundantly at multiple sites so that it can be used by the user even when some of the copies are not available due to site failures. A synchronization scheme for distributed information systems is described. The scheme increases the reliability as well as the degree of concurrency of the system. A token is used to designate a read-write copy. The scheme allows transactions to operate on a data object if more than one token copies are available. The availability of replicated data and the recovery mechanisms associated with the scheme are discussed.
