New and efficient paradigms for web-based collaborative product design in a global economy will be driven by increased outsourcing, increased competition, and pressures to reduce product development time. We have developed a three-tier (client-serverdatabase) architecture based collaborative shape design system, Computer Aided Distributed Design and Collaboration (CADDAC). CADDAC has a centrali...

We consider the problem of transmitting huge triangle meshes in the context of a Web-like client-server architecture. Approximations of the original mesh are transmitted by applying selective reenement. A multiresolution geometric model is maintained by the server. A client may query the server for a mesh at an arbitrary, continuously variable, level of detail. The client makes repeated queries...

Based on the framework defined in Chapter III, the fourth chapter discusses the models of information architectures that are used in implementing business computing solutions. In addition to the traditional mainframe-based architecture and most widely used client-server architecture, some recently developed architectures are briefly explained. This chapter aims at locating server configurations...

Denial of Service (DoS) attacks pose a fast-growing threat to network services in the Internet, but also corporate Intranets and public local area networks like Wi-Fi hotspots may be affected. Especially protocols that perform authentication and key exchange relying on expensive public key cryptography are likely to be preferred targets. A well-known countermeasure against resource depletion at...

Load balancing architectures can be used to solve overloading problems on web sites. Recently, most of the contents of web pages are retrieved from a database. Thus, the arrangement of the database server in a load balancing architecture is one of the most important factors that impact the overall performance. In this paper, we analyze the performance of load balancing architectures with a cent...

ecently, Web technologies have emerged as a credible alternative to client-server computing in corporate enterprise. Using information extracted from any ODBC-compliant DBMS and delivered over the Net, today's Web applications are moving from static HTML pages to full interoperability with corporate databases. Java, COM, CORBA, and related technologies (see sidebar, " Related Web Programming Te...

Information Systems with a large user base require thin client technology due to deployment issues. Configuration and version management, added to maintenance cost are major players on this decision. However, heavy traffic loads and network latency impose severe penalties on users. A candidate solution to this problem must optimize users ergonomics whilst keeping maintenance costs low. In a str...

Client-based intelligent tutoring systems present challenges for content distribution, software updates, and research activity. With server-based intelligent tutoring systems, it is possible to easily distribute new and updated content, deploy new features and bug fixes, and allow researchers to more easily perform randomized, controlled studies with minimal client-side changes. Building a scal...

Multi-server Federated learning (FL) has been considered as a promising solution to address the limited communication resource problem of single-server FL. We consider typical multi-server FL architecture, where coverage areas regional servers may overlap. The key point this architecture is that clients located in overlapping update their local models based on average model all accessible model...

This tutorial covers all primary technologies that can be used for Web programming with applications to the Internet based data acquisition and system control. The presentation is divided into two parts. The first part discusses several programming languages as programming tools. It provides in depth discussion of the tasks that are best to implement with and on the advantages versus challenges...
