AdpReplica:Adaptive Replica Management Mechanism
Wei Qing · 2004
In this paper, we present an Adaptive Replica Management Mechanism called AdpReplica. The AdpReplica constructs adaptive model regarding user anticipant availability and consistency maintenance overload as a function of a file's replica number. The AdpReplica model manages replica dynamically and maintains a rational replica number, not only satisfying the user anticipant availability, improving access efficiency and balancing overload, but also reducing bandwidth requirement, keeping the system stable and proving satisfied storage QOS.
