TL;DRAbstract

In order to strengthen the data consistency of asynchronous replication protocol, this paper presents an asynchronous replication protocol under fixed space-consistency (ARPFS). ARPFS can achieve fixed data consistency between the primary and backup systems by adjusting the response time of completing write requests dynamically. It is proved by experiments that ARPFS affords a performance between synchronous protocol and asynchronous protocol. It is useful to construct a practical replication system base on fixed data consistency.
