The HCSA (Hybrid Client-Server Architecture), a flexible system layout that combines the advantages of the traditional Client-Server Architecture (CSA) with those of the Shared Disk Architecture (SDA), is introduced. In HCSA, the traditional CSA-style I/O subsystem is modified to give the clients network access to both the server and the server's set of disks. Hence, the HCSA is more fault-tole...

This paper introduces a general architecture that could be employed to many Prolog applications to make them available on the Internet. The approach presented makes use of client-server architecture where the client is a relatively intelligent front end written in Java, and the server is the Prolog based application. Two applications developed using this architecture: an intelligent image retri...

With the development of Internet technology, the Web is becoming more and more important in our lives so that it has even become an essential element. The application of the Web has never been limited to computers; it has been opened to all kinds of intelligent digital devices like mobile ones. In this paper, we discuss the main and substantial difference between UDP and TCP, and how to impleme...

In light of advances in processor and networking technology, especially the emergence of network attached disks, the traditional client-server architecture becomes suboptimal for many computation/data intensive applications, e.g., data mining, scientiic computing, image processing, etc. In this paper, we introduce a revised architecture for this kind of application: the dynamic object server en...

One of the most common client/server architectures in enterprise systems today is the combination of object-oriented applications with active relational database systems. With this combination, developers have to overcome a difficult problem: the impedance mismatch between object orientation and the relational model. To date, there are several incomplete approaches for describing the integratio...

Definition A Multi-tier Architecture is a software architecture in which different software components, organized in tiers (layers), provide dedicated functionality. The most common occurrence of a multi-tier architecture is a three-tier architecture consisting of a data management tier (mostly encompassing one or several database servers), an application tier (business logic) and a client tier...

A key element to API technologies is the gateway. This is a Server architecture that provides the interface between client requests and the network services. Whilst it is in the interests of simplicity and ease of implementation for the client server interface to be as straightforward as possible, special consideration must be given to the interface to maintain security, integrity, scalability ...

ÐIn conventional video-on-demand systems, video data are stored in a video server for delivery to multiple receivers over a communications network. The video server's hardware limits the maximum storage capacity as well as the maximum number of video sessions that can concurrently be delivered. Clearly, these limits will eventually be exceeded by the growing need for better video quality and la...

This paper puts forward a model of Extended Client/Server (XCS) system, which is based on traditional Client/Server Architecture and borrows such merits from Browser/Server system as integrated code maintenance at Server-end and installation-free at Browser-end, etc. In an XCS system, Client is dynamically configured and automatically updated, and Server is able to commit self-health-checks and...

To protect the client–server architecture from a Distributed Denial of Service (DDoS) attack we present AI_Adaptive_POW. AI_Adaptive_POW protects an organization by injecting latency during communication generating client reputation adaptive puzzles, which need to be solved before server begins processing request. The framework adaptively tunes difficulty puzzle based on score calculated AI mod...
