Analysis and Comparative Study of Cache Replacement Policy

Day by Day increasing the human activity on internet, operating systems and databases, which create heavy network traffic. One of the measurable step in system designing is caching. It helps to get higher performance in various fields like databases, operating systems and World Wide Web. System performance differs according to various caching policies. Hit-ratio is one of the important factors in cache replacement policy. In caching systems, a replacement policy is necessary for determining when and what to evict from the cache. We discuss in this article about LRU, LFU, FIFO, CAR, OPTIMAL, WRP and AWRP algorithms.
