Abstract

Cache performance depends heavily on replacement algorithms, which dynamically select a suitable subset of objects for caching in a finite space. Developing such algorithms for wide-area distributed environments is challenging because, unlike traditional paging systems, retrieval costs and object sizes are not necessarily uniform. This paper presents the least-unified value algorithm, which performs better than existing algorithms for replacing nonuniform data objects in wide-area distributed environments.
