连铸智能化平台Web访问缓存替换策略

摘要

Currently,the continuous casting technology and information technology are highly integrated.However,the existing cache replacement strategies have limitations on the data transmission.This paper proposed a reference model to evaluate the spatial locality of Web object accessing,and used the reference model as the basis of a new cache replacement policy-greedy-dual-size reference (GDSR).GDSR improved the performance of cache replacement strategy,provided a new direction and ideas for the design of Web cache replacement policies.%针对目前连铸技术与信息化技术高度融合,但已有的缓存替换策略对于数据交互传输存在局限性的问题,提出一种引用度模型来对Web访问对象的空间局部性进行评价,并将其作为设计缓存替换策略的依据,提出一种基于引用度的缓存替换策略GDSR,改善了缓存替换策略的性能,为Web缓存替换策略的设计提供了一个新的方向和思路.
