Abstract
One of the keys to improve the performance of Content Delivery Network (CDN) is the efficiency of caching. To get the goal of improving caching efficiency, the main aim of current CDN caching algorithms is to obtain a higher caching hit ratio, while the validation and freshness of outdated pages have not received due consideration in these replacement models. In this paper, a new improved cache profit model is clearly defined, and the validation and freshness factors of Web pages have been taken into adequate account. Based on the profit model, a new caching replacement algorithm-EWCR (Efficient Web Caching Replacement) is proposed, and it is proved to be optimal based on reasonable assumptions. To conclude, a series of comparative experiments verifies the efficiency of EWCR in Web caching replacement.
