Abstract
The vast majority of current Internet traffic is generated by web browsing applications. Proxy caching, which allows some of the most popular web objects to be cached at intermediate nodes within the network, has been shown to provide substantial performance improve- ments. In this paper we argue that image-specific caching strategies are desirable and will result in improved performance over approaches treat- ing all objects alike. We propose that Soft Caching, where an image can be cached at one of a set of levels of resolutions, can benefit the over- all performance when combined with cache management strategies that estimate, for each object, both the bandwidth to the server where the object is stored and the appropriate resolution level demanded by the user. We formalize the cache management problem under these condi- tions and describe an experimental system to test these techniques.Keywords
