Replica synchronisation in grid databases
Sushant Goel, Hema Sharda, David Taniar · International Journal of Web and Grid Services · 2005
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.
