With the rapid growth of World Wide Web and Internet, a problem of improving web server’s performance is having primary importance. When a web user requests any resource from web server, he/she experiences some amount of delay which is known as User Perceived Latency. Web caching is an effective and economical technique to reduce UPL. Performance of web server can still be improved by predicting a future request from the current page and then move it to the web server’s cache. This concept is known as web cache pre-fetching. Web cache pre-fetching using markov tree and multidimensional matrix have limitations regarding to time complexity and memory, respectively. In this paper, an attempt has been made to use markov model and concept of stationary distribution for web cache pre-fetching. A comparison has been presented for proposed algorithms with Least Recently Used (LRU). Empirical results based on implementation confirm that proposed algorithms are better than LRU.

Abstract


With the rapid growth of World Wide Web and Internet, a problem of improving web server’s performance is having primary importance. When a web user requests any resource from web server, he/she experiences some amount of delay which is known as User Perceived Latency. Web caching is an effective and economical technique to reduce UPL. Performance of web server can still be improved by predicting a future request from the current page and then move it to the web server’s cache. This concept is known as web cache pre-fetching. Web cache pre-fetching using markov tree and multidimensional matrix have limitations regarding to time complexity and memory, respectively. In this paper, an attempt has been made to use markov model and concept of stationary distribution for web cache pre-fetching. A comparison has been presented for proposed algorithms with Least Recently Used (LRU). Empirical results based on implementation confirm that proposed algorithms are better than LRU.
