Prefetching Hyperlinks

نویسنده

چکیده

This paper develops a new method for prefetching Web pages into the client cache. Clients send reference information to Web servers, which aggregate the reference information in near-real-time and then disperse the aggregated information to all clients, piggybacked on GET responses. The information indicates how often hyperlink URLs embedded in pages have been previously accessed relative to the embedding page. Based on knowledge about which hyperlinks are generally popular, clients initiate prefetching of the hyperlinks and their embedded images according to any algorithm they prefer. Both client and server may cap the prefetching mechanism’s space overhead and waste of network resources due to speculation. The result of these differences is improved prefetching: lower client latency (by 52.3%) and less wasted network bandwidth (24.0%).

Adaptive Web Prefetching Scheme using Link Anchor Information

Web prefetching provides an effective mechanism to mitigate the user perceived latency when accessing the web pages. The content of web pages provide useful information for generating the predictions, which are used to prefetch the web objects for satisfying the user‟s future requests. In this paper, we propose fuzzy logic based web prefetching scheme that generates effective predictions for pr...

Prefetching the Means for Document Transfer: A New Approach for Reducing Web Latency

User-perceived latency is recognized as the central performance problem in the Web. We systematically measure factors contributing to this latency, across several locations. Our study reveals that DNS query times, TCP connection establishment, and start-of-session delays at HTTP servers, more so than transmission time, are major causes of long waits. Wait due to these factors also afflicts high...

Preprocessing of Web Usage Data for Application in Prefetching to Reduce Web Latency

-The Popularity of Web resulted in heavy traffic in the Internet. This intense increase in internet traffic has caused significant increase in the user perceived latency. In order to reduce this effectively. Prefetching techniques are found to be best suitable. Prefetching technique is motivated by the fact that, in general, once a user goes to a Web site; he/she generally browses around for se...

Semantic Web Prefetching Using Semantic Relatedness between Web pages

Semantic web prefetching makes use of the semantics of the keywords provided by the user for making predictions. These keywords can be descriptive texts like anchor texts, texts surrounding anchor texts, titles or simple text of the content. For finding the relation between two webpages, semantic information can be used. Semantic information is embedded within the web pages during their designi...

To Satisfy Impatient Web Surfers Is Hard

Prefetching is a basic mechanism for faster data access and efficient computing. An important issue in prefetching is the tradeoff between the amount of network’s resources wasted by the prefetching and the gain of time. For instance, in the Web, browsers may download documents in advance while a Web surfer is surfing on the Web. Since the Web surfer follows the hyperlinks in an unpredictable w...
