Abstract
Replication is the key factor in improving the availability of data in distributed information systems. Replicated data is stored 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. In this paper 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. Note: Abstract extracted from PDF file via OCR
