Research of Optimistic Replication in Distributed Peer-to-Peer Environment
Jing Liu · Jisuanji gongcheng · 2006
In distributed peer-to-peer environment, the replica of data object can be used to improve availability and performance. To guaranteeconsistency, update conflicts that arise in such a system must be detected and resolved. Optimistic replication is a way to preserve consistency andrelax the constraints on ordering. This paper proposes a formal model. And applying this model, it proposes the basic condition that guaranteeconsistency, proposes an algorithm that should be optimization in order to guarantee consistency, and extends the model to make it more suitable forreal environment.
