Toward Reconciling Availability, Consistency and Integrity in Replicated Information Systems

Abstract

The availability of information systems benefits from distributed replication. Different applications and users require different degrees of data availability, consistency and integrity. The latter are perceived as competing objectives that need to be reconciled by appropriate replication strategies. We outline work in progress on a replication architecture for distributed information systems. It simultaneously maintains several protocols, so that it can be re-configured on the fly to the actual needs of availability, consistency and integrity of possibly simultaneous applications and users
