COHERENCE DES DONNEES REPLIQUEES SUR LES GRILLES

Abstract

In distributed systems, the consistency of replicated data is one of the most important problems to solve, especially in data grid environment. In such environments, the availability of the latest value of the replicated data represents a big challenge to relieve, because the node that store this replicated data is dynamic. In this paper we study the problem of the replicated data in data grid systems. We propose an approach based on the quorum protocol and the entry consistency model, in order to assure the replica update propagation.
