RWAR: A Resilient Window-consistent Asynchronous Replication Protocol
Asynchronous replication protocol is playing an increasingly important role in the design of a remote disaster-tolerance system. A resilient window-consistent asynchronous replication protocol (RWAR) is presented in this paper RWAR increases the synchronous feature of asynchronous replication protocol by setting replication space-windows. This can achieve widow-consistency and decrease the risk of the inconsistency between the primary and backup systems. Simultaneously, RWAR dynamically adjusts the size of every space-window by setting checkpoints behind space-windows and calculating the system bandwidth-utility. This can strengthen the resiliency and flexibility of every space-window and ensure the replication performance of the primary system. It's proved with experiments that RWAR affords trade-off between data consistency and replication performance. It is helpful to construct a practical replication-based disaster-tolerance system
