Retrieve Scalable Image Contents over Image Contents Network by Efficient Caching Algorithms

Recently how to retrieve Web contents efficiently over the Internet has been an important issue, because large-sized contents (such as image and video) always take heavy load to the end users. Scalable (layered) format is considered as one of appropriate solutions for the above problem because of its better flexibility and functionality. However, the corresponding caching method for scalable format has not been resolved. Therefore, this paper is to talk about the caching algorithms to retrieve and deliver scalable Web image contents over the Internet. We compare several caching methods and give a conclusion on how to further improve the Web performance by assigning efficient caching algorithms.
