Web content hosting, in which a Web server stores and provides Web access to documents for different customers, is becoming increasingly common. For example, a web server can host webpages for several different companies and individuals. Traditionally, Web Service Providers (WSPs) provide all customers with the same level of performance (best-effort service). Most service differentiation has be...

This paper presents a server-based hybrid cryptographic protocol, using quantum and classical resources, to generate a key for authentication and optionally for encryption in a network. A novel feature of the protocol is that it can detect a compromised server. Additional advantages are that it avoids the requirement for timestamps used in classical protocols, guarantees that the trusted server...

Public information systems offering access to the network community can be divided into two groups: those with stateful protocols and those with stateless protocols. Evolving client-server protocols like the Hypertext Transfer Protocol (HTTP) of the World-Wide Web (W3) are stateless. In this case the reaction of the information server depends on the request only. To access the server, special c...

Server load balancing is indispensable within World Wide Web (WWW) for providing high-quality service. In server load balancing, since the server loads and capacities are not always identical, traffic should be distributed by measuring server performance to improve the service quality. This study proposes a load balancing technique conducted by passive measurement, which estimates the server pe...

This paper focuses on the problem of accessing interactive information servers ("interactive sessions" in W3-terminology, e.g. an existing library information system) directly with a W3-browser instead of opening an additional viewer (e.g. a terminal emulation program). IDLE is a language designed to describe the user interface of interactive information servers in a way that allows automatic t...

While traditional Internet servers mainly served static and later also dynamic content, the popularity of Web services is increasing rapidly. Web services incorporate additional overhead compared to traditional web interaction. This overhead increases the demand on Internet servers which is of particular importance when the request rate to the server is high. We conduct experiments that show th...

Distributed processing systems are considered to solve the challenging requirements of trigger and data acquisition systems for future HEP experiments. The aim of this work is to present a software environment to control and monitor large scale parallel processing systems based on a distributed client-server approach developed in Java. One server task may control several processing nodes, switc...

This paper describes a possible way of controlling access to image data via the World Wide Web. It describes how images are encrypted using a novel technique and delivered from a server. When exchanging data, a protocol ensures that requests are always tied to a registered user and that all critical data are transferred in encrypted form. User actions are permitted and logged by the server. Act...
