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

Abstract”
Here describe a software router capable of flexible service composition through plug and play of specialized Java software modules. These Java modules “ previously developed for network simulation in the J-Sim project “ are leveraged for actual deployment on our router through a JSocket class of objects. Our system provides significant software engineering benefits of simplified code development and safe composition/reuse of various router c ....etc

Atomicity is a highly desirable property for achieving application consistency in service compositions. To achieve atomicity, a service composition should satisfy the atomicity sphere, a structural criterion for the backend processes of involved services. Existing analysis techniques for the atomicity sphere generally assume complete knowledge of all involved backend processes. Such an assumption is invalid when some service providers do not release all details of their backend processes to service consumers outside the organizations. To addres ....etc

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
