Abstract:
In Blue Whale Cluster File System(BWFS), inconsistency of resource state may exist during distributed resource transference under system exception. To solve that problem, the consistency protocol S2PC-RT is presented. Resource transference sequence no. is introduced to protect consistency and space for resource applying added to reduce message wait. The correctness of S2PC-RT is proven. Implementation and test are done in BWFS, and test results show that S2PC-RT can guarantee the resource consistency and enhance the performance of distributed resource transference operations.
Key words:
Blue Whale Cluster File System(BWFS),

摘要: 在蓝鲸集群文件系统中,分布式资源交互在系统异常的情况下会出现资源状态不一致的情况,为解决这一问题,该文提出分布式资源交互一致性协议S2PC-RT。S2PC-RT引入资源交互序号保证一致性,通过增加资源申请空间减少消息等待。证明协议的正确性,并在蓝鲸集群文件系统中实现了协议。测试结果表明,S2PC-RT能够保证资源的一致性,有效提高分布式资源的交互性能。
