Generalized Grid Quorum Consensus for Replica Control Protocol
Vinit Kumar, Ajay Kumar Agarwal · 2011
In distributed systems it is often necessary to provide coordination among the multiple concurrent processes to tolerate the contention, periods of asynchrony and a number of failures. Quorum systems provide a decentralized approach for such coordination. In this paper, we propose a replica control protocol by using a Generalized-grid quorum consensus, which is the generalization of a Read-one-write-all (ROWA), Grid quorum consensus, D-Space quorum consensus and Multi-dimensional-grid quorum consensus protocols. This protocol provides a very high read availability and read capacity while maintaining the reconfigurable levels of write availability and fault tolerance.
