Prefetchability Model of Web Objects

Current prefetching models mainly depend on prediction algorithms to fetch Web objects in advance, but lack the consideration of the prefetchability of Web objects. If the prefetchability of the objects can be considered before prefetching, unnecessary prefetching will be decreased to some extent. On one hand, it can improve hit ratio of prefetching algorithms, on the other hand it can reduce unnecessary network bandwidth and system load. Prefetchability concept and measurement method of Web objects are described in detail in the paper, which can be used to make prefetching model more efficient and controllable
