Abstract: Grid architecture is heterogeneous in nature. Replica synchronisation protocols, normally used in homogeneous systems, are not applicable in heterogeneous architectures. In this paper, a replica synchronisation protocol for heterogeneous Grid architecture is proposed. The protocol uses the Grid middleware|s metadata service and timestamps to synchronise the replicas among distributed sites. The protocol is then extended to handle multiple network partitioning. Grid sites are prone to multiple network partitioning. Most of the replica synchronisation protocols deal with simple network partitioning. The protocol and use contingency quorums are extended to deal with multiple networks partitioning in Grid databases.

Keywords: quorum-based systems; replica synchronisation protocols; data grid; grid computing; heterogeneity; autonomy; distributed systems; grid services; grid databases; multiple network partitioning; consistency; data management.
