A Client-Side Cloud Cache Replacement Policy

To deliver data-centric cloud computing services heavily relies on data networks between cloud providers and consumer premises. The continuous and rapid growth of data hosted in external private clouds accelerates downstream network-bandwidth saturation and public cloud data-out overspends. The consumer-initiated replication of cloud data to consumer locality is a solution and known as clientside cloud caching. This paper presents the core mechanism of the cloud caching, called Cloud cache replacement policy. Simulations shown that 1) Cloud saved network bandwidth, data-out charge and data loading time; 2) even Clouds performance minima outperformed three well-known web cache replacement policies across all performance metrics for almost all test cases; 3) Cloud importantly attain optimal hit and byte-hit ratios without sacrificing one to the other.
