摘要：
By allowing read operations to succeed even when only an insufficient number of replicas is accessible, the read availability can be significantly increased. This paper presents such a weak consistency approach for replicated data in a networking environment. A method for estimating the "degree of correctness" of those modified read operations is proposed. Write operations, though, remain unchanged. It is shown that this approach is applicable to a large number of replication control strategies. Furthermore, we demonstrate its advantages by analysing two sample strategies.
