A Hybrid Protocol for Replicas Management in Data Grid
In large scale distributed systems, replication is a popular technique for improving the accessibility of information and surviving the unreliability of communication networks. Pessimistic replication and optimistic replication are two contrasting replication models. They represent the two extremes in the availability-consistency. Pessimistic replication favors consistency over availability, wh...
متن کاملConsistency Management in Optimistic Replication Algorithms
Optimistic replication algorithms allow replica contents to become stale but in a controlled way. In return, they become far more efficient and available than traditional replication algorithms that keep all the replicas consistent, especially when the network and computers are unreliable. The use of optimistic replication has grown explosively due to the proliferation of the use of the Interne...
متن کاملMeaningful Metrics for Evaluating Eventual Consistency
Optimistic replication is a fundamental technique for supporting collaborative work practices in mobile environments. However, eventual consistency, in contrast to immediate strong consistency in pessimistic replication, is much harder to evaluate. This paper analyzes different metrics for measuring the effectiveness of eventually consistent systems. Using results from a simulated environment o...
متن کاملOptimistic Replication and Resolution
Data replication places physical copies of a shared logical item onto different sites. Optimistic replication (OR) allows a program at some site to read or update the local replica at any time. An update is tentative because it may conflict with a remote update. Such conflicts are resolved after the fact, in the background. Replicas may diverge occasionally but are expected to converge eventual...
متن کاملA New Optimistic Replication Strategy for Large-scale Mobile Distributed Database Systems
This paper proposes a new optimistic replication strategy for maintaining the eventual consistency in large-scale mobile distributed database systems. The proposed strategy consists of three components in order to support the characteristics of such systems. These components are: replication architecture, updates propagation protocol, and replication method. The purpose of the replication archi...
