摘要 探讨了在网格环境中数据复制的相关策略,包括动态只读复制策略和动态读/写复制策略。动态复制策略可以用来减少带宽消耗和访问延迟,不同的复制策略在不同的访问方式下有不同的性能表现。同时,提出了动态读/写复制策略的Fast Upload算法,算法支持数据传输过程中的并发复制,通过复制锁机制来维护复制与更新数据的一致性。 In this paper, the replica strategies are discussed, including Dynamic read-only Replication Strategies and Dynamic read/write Replication Strategy. Dynamic Replication Strategies can reduce bandwidth consumption and access latency in accessing the huge amounts of data. The Dynamic read/write Replication Strategy named as 'Fast Upload' is proposed. Fast Upload enables updating while data transporting, and the replica lock mechanism ensures the consistency of the data source and different replica.
