摘要: 针对分布式环境下高频率异地数据访问造成的系统性能下降的问题,对SBM模型进行改进,提出分布式缓存系统D-Cache,给出基于最优价值度的缓存文件替换算法——OCV。数字模拟实验结果证明,与DartCache系统相比,D-Cache系统能更有效地减少系统访问延迟,增加吞吐量,提高分布式环境下系统的性能。

Abstract: In the distributed environment, the high frequency of remote data access leads to a decline in system performance. Aiming at this problem, this paper improves the SBM model, and designs a Distributed Cache system(D-Cache). A new cache replacement algorithm, OCV is given. Digital simulation results demonstrate that D-Cache system can shorten the response time of system and increase the throughput of system more effectively, which improves performance in the distributed environment, compared with the distributed cache system DartCache.
