Consistency Protocol of Resource Transference in Blue Whale Cluster File System

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.
