Abstract

Data replication is a central technique to increase availability and performance of distributed systems. While offering many advantages it also requires more effort for ensuring data consistency in case of updates. In the research literature various approaches for replication management in distributed databases have been presented, but they are mostly limited either in scalability or in the consistency guarantees they provide. On the other hand, P2P systems usually provide replication support but ignore the update problem. In this paper we present a new approach for managing replicated data in wide area distributed networks. Our solution is orthogonal to the underlying infrastructure and managed in a decentralized manner. It guarantees single-master consistency and allows updates at any node of the system by combining traditional replication techniques with ideas known from P2P systems.
