Abstract
Distributed system rely on replication techniques t o tolerate data failure and site disconnection thus ensur-ing flexibility of the system so as to preser ve its dependability. The idea of replication is ro bust however practical implementation of the replication techniques is often rigid that would bring down system’s de-pendability and performance. This study intended to evaluate existing techniques and then develop a new technique which later will be compare d with the existing with the goal of to achieve better fault tolerance, dependability and performan ce in distributed systems. The new technique is constructed based on circular neighbor relationship and quorum-based protocol. The consistency and integrity of the replicated data that involved writ e and read operations on the replicas is ensured us ing Replica maintenance protocol. This techniques focus ed on synchronous solution as for its quorum execution or commitment protocol showed higher reliability and convenience to avoid conflicts compared to asynchronous solution.
Highlights
The rest of the paper is organized as follows: Section 2 discusses several replication techniques and presents the Replication method is a powerful tool to ensure research background of the new circular neighbor availability and reliability in fault tolerant computing. replication
The concept of neighbor replication is all-data-to-somesites where only neighbors are considered to have the replicated data. This assignment provides a higher availability of executing write operations in replicated database due to the minimum number of quorum size required in Neighbor Replica Triangular Grid (NRTG) (Mamat et al, 2006)
Replication technique primarily concentrates on the two fault tolerance manners ensuring flexibility of the distributed system so as to preserve its dependability

The rest of the paper is organized as follows: Section 2 discusses several replication techniques and presents the Replication method is a powerful tool to ensure research background of the new circular neighbor availability and reliability in fault tolerant computing. The idea of replication is robust, it is often a difficult challenge to determine practical implementation technique with the possible maintenance protocol. Of a replication technique since each replication technique involves different levels of complexity
