This paper aims to justify the need for refining the concept of the traditional three-tier client-server architecture to address the drastic changes we have encountered in the form of information processing needs demanded by the public and the information processing services supplied to the public. The paper suggests much needed revisions to the traditional approach and demonstrates how the Inf...

At this stage the application server systems, such as e-commerce platform , instant messaging system , enterprise information system and so on, will be led to lose connections , the data latency phenomena because of too much concurrent requests, application server architecture, system architecture, etc. In serious cases, the server is running blocked. The new type of application server system c...

The aim of this graduate project was to develop a prototype of a C# Managed DirectX Client Server Library for Shared Environments and to explore and learn networking in the C#.Net environments. A demo Teapot program has been implemented as a prototype which is implemented in C# and DirectX. This prototype contains five components namely a Server GUI, a Server library, a Client GUI, a Client Lib...

In this paper we describe a novel approach to displaying complex 3D scenes on architecture that does not have support for 3D graphical display. Our system makes use of distributed graphics, employing a standard workstation as a server. This server communicates with a client via UDP sockets over a LAN link. To minimize network traffic, a compression engine is employed to compress and decompress ...

This Video data is stored in a video server for delivery to multiple receivers over a communications network in a traditional video-on-demand system. The hardware in this video server has the following limitations: 1) the maximum storage capacity, and 2) the maximum number of video sessions that can simultaneously be delivered. We propose a novel Adaptive-Multiple-VIdeo-Server -Architecture (AM...

Recently, Peer to Peer(P2P) networks become more and more popular. This paper describes an implementation of real-time video conference system using high speed multimedia communication. The proposed real-time video conference system has hybrid Peer to Peer architecture based on a client-server and peer-to-peer, where client-server is used for exchange of account management, client list and stat...

Classical models of database-driven web applications follow thin-client architectures, i.e., all data processing and business logic resides on the server while the client’s role is to arrange and display the user interface. When transactions come into play, which may naturally span several consecutive interactions between client pages and server actions, problems arise since transactions cannot...

The paper discusses the possibility of adaptation of Web Services Architecture (WSA) in distributed embedded systems. It provides a brief description of this architecture and a tool for creating services in Java and C/C++. A three-tier client/server model of a distributed system for monitoring of temperature and humidity is presented and techniques for adaptation of this model to the WSA are pr...

This paper identifies the current difficulties faced by the IT professionals working for collaborative enterprises and explains how we exploit and extend the so-called stateless client systems to support those individuals in cooperative work. Stateless client systems are the software tools that separate the display interface from the application logic in windowing systems. They embed a client/s...

We present a simple and robust client–server architecture for streaming synchronized multimedia presentations to mobile terminals over a low-bandwidth connection. The server is similar to a compiler, and translates high level SMIL descriptions of multimedia presentations into low level content instructions. The client resembles a virtual machine, operating on content instructions that control t...
