    Notes: There has been an explosion in the number of retail Web sites since 1995, e-retail offering shares a few common elements specifically a product search facility (often augmented by a product evaluation facility), an on-line purchase function and a product delivery capability. There is a body of theory and empirical research in the study of customer loyalty drivers in the services sector, which demonstrates that customers evaluate services on the basis of tangibles, responsiveness, empathy, assurance, reliability and control. These service qualities depend on the customer's perception of the overall service experience. The most influential element in the service experience is the relationship between the service provider and the customer. The Internet is a poor service delivery medium, it lacks the capacity for direct personal interaction enjoyed by non-Internet based services. Sets out a number of marketing and Website design implications for e-retailers and suggests means by which e-retailers can manage customer perceptions to increase sales and develop greater customer loyalty.

    Notes: Web traffic is doubling every year, according to recent global studies. The user needs more information from Web sites and wants to spend as little time for downloading as possible. Simultaneously, more Internet bandwidth is needed and all ISPs are trying to build high bandwidth networks. This paper presents a case study that calculates the reduction of the time needed for a Web page to be fully downloaded and delivered to the user. Presents a way to calculate the reduction of data transfer, bandwidth resources and response time when the HTTP/1.1's compressing feature is enabled (either in plain hypertext files or the text output of CGI programs or dynamically generated pages). Measurements are taken from five popular Web sites in order to validate our statement for reduction in transfer time. The definition of the mean size of a Web page that commercial Web sites have is additionally in the scope of this paper.

    Notes: The Internet is an open and global programming environment where applications and services mostly follow the traditional client/server model. The use of new programming paradigms based on mobile entities, such as mobile agents (MA), can accelerate the process of diffusion of new applications and services in the areas of e-commerce, network and systems management, and mobile computing. However, the lack of security is one of the main obstacles to a wide diffusion of MA. On the one hand, mobility increases the potential of security breaches because of the injection of possibly malicious MAs; on the other hand, it introduces the new issue of protecting MAs against integrity and secrecy attacks from their execution environments. This paper discusses the security issues introduced by the MA technology and proposes a security architecture composed of a wide set of services and components, which adequately fulfil the requirements of several application areas. The implementation of the security framework in the secure and open MA system has provided the support for the development of a secure electronic marketplace prototype that demonstrates the effectiveness of adopting the MA technology in the Internet environment.

    Notes: This paper presents a non-intrusive method of determining network performance parameters for voice packet flows within a Voice over IP, or Internet Telephony call. An advantage of the method is that it allows not only end-to-end performance monitoring of flows, but also makes it possible to inspect the transport parameters of a specific network or link when delay sensitive traffic transits through it. The results of a preliminary test, to check the validity of the method, are also included.

    Dynamic Web pages: performance impact on Web servers (2001)

    Notes: The World Wide Web has experienced phenomenal growth over the past few years, placing heavy load on Web servers. Today's Web servers also process an increasing number of requests for dynamic pages, making server load even more critical. The performance of Web servers delivering static pages is well studied and well understood. However, there has been little analytic or empirical study of the performance of Web servers delivering dynamic pages. This paper focuses on experimentally measuring and analyzing the performance of the three dynamic Web page generation technologies: CGI, FastCGI and Servlets. In this paper, we present experimental results for Web server performance under CGI, Fast CGI and Servlets. Then, we develop a multivariate linear regression model and predict Web server performance under some typical dynamic requests. We find that CGI and FastCGI perform effectively the same under most low-level benchmarks, while Servlets perform noticeably worse. Our regression model shows the same deficiency in Servlets' performance under typical dynamic Web page requests.

    An applet-based anonymous distributed computing system (2001)
    Bingley : Emerald

    Notes: Anonymous distributed computing systems consist of potentially millions of heterogeneous processing nodes connected by the global Internet. These nodes can be administered by thousands of organizations and individuals, with no direct knowledge of each other. This work defines anonymous distributed computing systems in general then focuses on the specifics of an applet-based approach for large-scale, anonymous, distributed computing on the Internet. A user wishing to participate in a computation connects to a distribution server, which provides information about available computations, and then connects to a computation server with a computation to distribute. A Java class is downloaded, which communicates with the computation server to obtain data, performs the computation, and returns the result. Since any computer on the Internet can participate in these computations, potentially a large number of computers can participate in a single computation.

    Notes: Nowadays the Internet offers a large amount of information to a wide range of users, making it difficult to deal with. The present work suggests the use of intelligent agents for the personalized filtering of Web pages. A set of autonomous, non-mobile and adaptive agents was developed, aiming to satisfy the user's need for information. The agents learn from the users' feedback and attempt to produce better results over time. This work presents the system description and the promising results of tests performed in a simulated environment. The proposed system has proven to be a useful tool in reducing the amount of information with which the user has to deal.

    Notes: Automatic, autonomous browsing has an increasingly important task in information discovery and assisted browsing on the Internet. Where users could once keep up to date with information of interest on the Internet, the recursive growth of the network has made this process increasingly time consuming and less rewarding. Presents two possible solutions to this problem: Data Agents and CollaborAgents which were developed with IBM's Aglet Workbench - a particular implementation of mobile agents. Also surveys the agent technology and discusses the agent building package used to develop both mentioned applications. Concludes that the future of local interaction, reduced network loading, server flexibility and application autonomy which are supported by mobile agent technology, all help to provide a level agility above distributed problem solving.

    Access control for agent-based computing: a distributed approach (2001)

    Notes: The mobile software agent paradigm provides a generic, customisable foundation for the development of high performance distriubuted applications. An efficient, general-purpose access control mechanism is required to support the development of a wide range of applications. This is achievable if the design of the access control system is based on the principles of simplicity, programmability (customisation) and reusability. However, existing mobile agent architectures either neglect this issue, or offer centralised schemes that do not support adaptive access control on a per-agent basis and do not address the issues of secure knowledge sharing and reusing. In this paper a simple, distributed access control architecture is presented, based on the concept of distributed, active authorisation entities (lock cells), any combination of which can be referenced by an agent to provide input and/or output access control. It is demonstrated how these lock cells can be used to implement security domains and how they can be combined to create composite lock cells.

    Notes: MOOsburg is a community-oriented multi-user domain. It was created to enrich the Blacksburg Electronic Village by providing real-time, situated, interaction, and a place-based information model for community information. We are experimenting with an implementation fundamentally different from classic multi-user domains object-oriented (MOOs), supporting distributed system development and management, and a direct manipulation approach to navigation. To guide the development of MOOsburg, we are focusing on a set of community-oriented applications, including a virtual science fair.
