SNAP, Crackle, WebWindows!

We elaborate the SNAP---Scalable (ATM) Network and (PC) Platforms---view of computing in the year 2000. The World Wide Web will continue its rapid evolution, and in the future, applications will not be written for Windows NT/95 or UNIX, but rather for WebWindows with interfaces defined by the standards of Web servers and clients. This universal environment will support WebTop productivity tools, such as WebWord, WebLotus123, and WebNotes built in modular dynamic fashion, and undermining the business model for large software companies. We define a layered WebWindows software architecture in which applications are built on top of multi-use services. We discuss examples including business enterprise systems (IntraNets), health care, financial services and education. HPCC is implicit throughout this discussion for there is no larger parallel system than the World Wide metacomputer. We suggest building the MPP programming environment in terms of pervasive sustainable WebWindows technologies. In particular, WebFlow will support naturally dataflow integrating data and compute intensive applications on distributed heterogeneous systems

Software agents in network management

The globalisation of Internet technology had a strong impact on technology price and availability, which resulted in the emerging of more opportunities and more services in distance learning, electronic commerce, multimedia and many others. From the user perspective, there is a need for more comprehensive interfaces. From the network perspective, the introduction of QoS and the upcoming of new and more complex services led to additional bandwidth and management requirements. The amount of management information produced by applications, workstations, servers and all kind of network components is increasingly hard to process. All this information can be filtered by an intelligent network management system, capable of proactive management. This paper intents to highlight the role of newer paradigms, such as Software Agents, in Network Management frameworks. The use of intelligent programs that substitutes the user in boring, repetitive or information intensive tasks can help in the resolution of problems such as congestion, reliability, real-time response and many others

Internet-based Multiagent Architecture

Research in intelligent agents and multiagent systems that run on the Internet has received increased attention and importance in recent years. Since the Internet continues to grow, intelligent agent technology is progressively being introduced to many Internet-based applications for communications between different applications. The aim of this paper is to present an Internet-based architecture for multiagent systems which offers a communication infrastructure and coordination services for agents to achieve their goals. A structured architecture is proposed to support communication facilities among several agents and coordinate agent activities in distributed environments such as the Internet and Intranets. The architecture consists of 1) Application agents, 2) Communication handler, 3) Knowledge manager, and 4) Repository. (Yuen, et al. 1999; Leung, et al. 1999). These four layers cooperate together and provide common facilities necessary for typical multiagent systems or agent-based applications with various choices. An Internet-based prototype for auditing and detecting unauthorized transactions within an organization over the Internet or an Intranet is implemented to demonstrate the practicability and feasibility of the proposed Internet-based architecture for multiagent systems

A Competency Based MSIS Curriculum

In response to the changing industry demands and increasing diversity of student needs when embarking on IS graduate studies, we determined that a fundamental redesign of the MSIS curriculum was necessary. We saw that the expanding IT universe now has more specialties than ever before while competitive forces simultaneously demand that firms keep costs under strict controls. Facing such pressures, firms demand more from IT professionals in the breadth and depth of their IT knowledge and skills coming from numerous knowledge domains. From these trends and issues we formulated the competency concept that forms the foundation for the new curriculum. A student earns a competency by completing four courses in a module. Now students can choose to pursue multiple competencies and can return to upgrade skills after graduation. We describe the process and issues we faced as well as the competency-based modular curriculum. We end with discussing the remaining issues that we are handling

A Survey of Distributed Enterprise Network and Systems Management Paradigms

Since the mid 1990s, network and systems management has steadily evolved from centralized paradigms, where the management application runs on a single management station, to distributed paradigms, where it is distributed over many nodes. In this survey, our goal is to classify all these paradigms, especially the new ones, in order to help network and systems administrators design a management application, and choose between mobile code, distributed objects, intelligent agents, etc. Step by step, we build an enhanced taxonomy based on four criteria: the delegation granularity, the semantic richness of the information model, the degree of specification of a task, and the degree of automation of management

Improving Collaborative Learning Using Pervasive Embedded System-Based Multi-Agent Information and Retrieval Framework in Educational Systems

E-learning is a form of Technology SupportedEducation where the medium of instruction is throughDigital Technologies, particularly Computer Technology.An instance is the use of search engines like Google andYahoo, which aid Collaborative Learning. However, thewidespread provision of distributed, semi-structuredinformation resources such as the Web has obviouslybrought a lot of benefits; but it also has a number ofdifficulties. These difficulties include people gettingoverwhelmed by the sheer amount of information available,making it hard for them to filter out the junk andirrelevancies and focus on what is important, and also toactively search for the right information. Also, people easilyget bored or confused while browsing the Web because ofthe hypertext nature of the web, while making it easy to linkrelated documents together, it can also be disorienting. Toalleviate these problems, the Web Information Food ChainModel was introduced. How effective has this been with thedynamic nature of computing technologies? Pervasivecomputing devices enable people to gain immediate accessto information and services anywhere, anytime, withouthaving to carry around heavy and impractical computingdevices. Thus, the bulky PCs become less attractive andbeing slowly eroded with the development of a newgeneration of smart devices like wireless PDAs, smartphones, etc. These embedded devices are characterized bybeing unobtrusively embedded; completely connected;intuitively intelligent; effortlessly portable and mobile; andconstantly on and available. This paper presents the use ofembedded systems and Intelligent Agent-Based WebInformation Food Chain Model in Multi-Agent Informationand Retrieval Framework (IIFCEMAF), to realizing fullpotentials of the internet, for users’ improved system ofcollaborative e-learning in education
