A Web Service for evaluation of load balancing strategies for distributed web server systems

Number of users accessing the Internet is increasing quite rapidly and it is common to have more than 100 million hits a day for popular web sites. For example, netscape.com website receives more than 120 million hits a day. The number of users is expected to continue increasing at a fast rate and hence any website that is popular, faces the challenge of serving very large number of clients with good performance. Full mirroring of web servers or repl ....etc

Geographically Distributed Web Crawler

Introduction
Web crawling is a resource intensive process, both in terms of processing and in terms of communication. Distributing the crawling activity among multiple machines can distribute processing, and spreading out the distribution geographically can significantly reduce the communication cost. The reduction in communication is because of the following reasons. ¢By choosing a crawler nearer to a web server being crawled, the http fetch of the content on the web server ....etc

WDDX (Web Distributed Data eXchange) is a programming-language-neutral data interchange mechanism to pass data between different environments and different computers. It supports simple data types such as number, string, boolean, etc., and complex aggregates of these in forms such as structures and arrays. There are WDDX interfaces for a wide variety of languages. The data is encoded into XML using an XML 1.0 DTD, producing a platform-independent but relatively bulky representation. The XML-encoded data can then be sent to another computer usi ....etc

Abstract
Many large web sites get millions of hits everyday. They need a scalable web server
system that can provide better performance to all the clients that may be in different
geographical regions. Common approach to improve performance is to have fully
replicated web server clusters in different geographical regions with replicated
servers. In such an environment, one of the most important issues is selecting a server
for servicing a request. Client requests should be directed to a server such that the
time taken for servici ....etc

Distributed-Input-Distributed-Output (DIDO) Wireless Technology



Abstract

Distributed-Input-Distributed-Output (DIDO) wireless technology is a breakthrough approach that allows each wireless user to use the full data rate1 of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the same spectrum. With conventional wireless technologies the data rate available per user drops as more users share the same spectrum to avoid interference, but with DIDO, the data ....etc
