Web content delivery is based on client-server model. In this model, all the web requests for specific contents are serviced by a single web server as the requested contents reside only on one server. Therefore, with the increasing reliance on the web, the load on the web servers is increasing, thus causing scalability, reliability and performance issues for the web service providers. Various t...

As the Web evolves from providing information access into a platform for e-business, there is a need for technologies to support dynamic inter-enterprise collaboration. Toward this goal, we have developed Internet Business Servers (IBSs). This approach essentially turns individual Web servers into communicating and collaborating servers, with extended functionality for inter-enterprise business...

This paper discusses the curriculum development of a teaching module for embedded web servers as well as the design and development issues for such web servers. The module is supported by practical lab sessions where the students configure and program such an embedded web server by generating html files to monitor the temperature and filling level of a fridge, and to also regulate the temperatu...

Providing high quality of Web services is now very important for most of the services. In this article, we present the MLF (Most Loaded First) system, adaptive and intelligent cluster-based Web system. The MLF system provides Quality of Web Service (QoWS) on a fixed level, guaranteeing the page response time within established boundaries, even if Web servers are heavy loaded. We present experim...

A great deal of research has been devoted to tackling the problem of network congestion against the increase of Internet traffic. However, there has been little concern regarding improvements of the performance of Internet servers in spite of the projections that the bottleneck is now being shifted from the network to endhosts. We have previously proposed a scheme called SSBT (Scalable Socket B...

In the current Internet, many HTTP sessions are established between Web clients and servers via Web proxy servers. Since the Web proxy server accommodates lots of TCP connections from Web client hosts, and those to Web servers, it cannot show sufficient performance if the resources of the proxy server should be utilized effectively. In this paper, we propose a new resource management scheme for...

Traditional techniques for a distributed web server design rely on manipulation of central resources, such as routers or DNS services, to distribute requests designated for a single IP address to multiple web servers. The goal of the Distributed Cooperative Web Server (DCWS) system development is to explore application-level techniques for distributing web content. We achieve this by dynamicall...

The function of non-coding RNA genes largely depends on their secondary structure and the interaction with other molecules. Thus, an accurate prediction of secondary structure and RNA-RNA interaction is essential for the understanding of biological roles and pathways associated with a specific RNA gene. We present web servers to analyze multiple RNA sequences for common RNA structure and for RN...

As a growing number of web sites introduce mirrors to increase throughput, the challenge for clients becomes determining which mirror will offer the best performance when a document is to be retrieved. In this paper we present findings from measuring 9 clients scattered throughout the United States retrieving over 490,000 documents from 47 production web servers which mirror three different web...
