Network Re Engineering

Network Re-Engineering: Foundations of Enterprise Computing deals with the aspects of an organization's information systems and communications assets. This book reviews the foundations of enterprise computing including servers, client/server computing, local area networks, user interfaces, and emerging cross-platform development. The coverage of an enterprise computing system needs efficient communication facilities over which interoperability and information sharing devices can operate. This text explains the basic technologies and services that an enterprise computing environment requires: protocol stacks, communications technologies, fundamental interoperability. For example, electronic mail must conform to the CCITTX.400 specifications. Electronic mail systems include message handling, message typing or protocols, naming and addressing, and distribution lists. The book discusses two types of architectures for enterprise computing, namely, the OSE/1 APP and the CA09s. This text also notes that developing enterprise-class applications can be either through a direct development that meet the requirements of the enterprise or through migration of an existing system to a new one. This book can prove useful for programmers, systems officers, computer engineering instructors, and advanced students in computer science.

Using a friendly, tutorial format that assumes no expertise, this book provides step-by-step guidance for implementing modifications in current networks. It shows network managers how to identify the factors that justify network modification and how to plan for continual change without continual reinvestment.

Requirements elicitation is the extraction of users’ requirements. This process has been affected by legacy systems which are outdated computer systems that are no longer applicable to current contexts but are being used instead of available upgraded versions. Re-engineering will play an important role in the decision making process, especially the way the data is collected and presented through a computing platform. The study establishes appropriateness of existing Elicitation Techniques, determine appropriate Attributes for re-engineering legacy systems and design a Frame work used during elicitation process.

Contributing to the development and the enrichment of the European dimension in Engineering Education (EE), constituted the global goal of TREE. In other words to enhance the compatibility of the many diverse routes to the status of Professional Engineer which exist in Europe and, hence, to facilitate greater mobility of skilled personnel and integration of the various situations throughout Europe. The activity of the TN TREE, made up by some 110 higher education Institutions and Associations, has been developed along four main lines: A. the tuning line B. the education and research line C. the attractiveness of EE line D. the sustainability line This volume, accompanied by a CD Rom, presents the results of three years of works in the frame of the Thematic Network TREE which was activated and financed in the frame of the SOCRATES Programme in the period 2004-2007.

Today enterprises must strive to improve their competitiveness in a changing environment. To reach this objective it is necessary for companies to evaluate their performances and to combine modelling, business process re-engineering and benchmarking techniques. This book demonstrates the successful combination and implementation of these various techniques.

A highly practical guide rooted in theory to include the necessary background for taking the reader through the planning, implementation and management stages for each type of cellular network. Present day cellular networks are a mixture of the technologies like GSM, EGPRS and WCDMA. They even contain features of the technologies that will lead us to the fourth generation networks. Designing and optimising these complex networks requires much deeper understanding. Advanced Cellular Network Planning and Optimisation presents radio, transmission and core network planning and optimisation aspects for GSM, EGPRS and WCDMA networks with focus on practical aspects of the field. Experts from each of the domains have brought their experiences under one book making it an essential read for design practitioners, experts, scientists and students working in the cellular industry. Key Highlights Focus on radio, transmission and core network planning and optimisation Covers GSM, EGPRS, WCDMA network planning & optimisation Gives an introduction to the networks/technologies beyond WCDMA, and explores its current status and future potential Examines the full range of potential scenarios and problems faced by those who design cellular networks and provides advice and solutions all backed up with real-world examples This text will serve as a handbook to anyone engaged in the design, deployment, performance and business of Cellular Networks. "Efficient planning and optimization of mobile networks are key to guarantee superior quality of service and user experience. They also form the essential foundation for the success of future technology development, making this book a valuable read on the road towards 4G." —Tero Ojanperä, Chief Technology Officer, Nokia Networks

This handbook distils the wealth of expertise and knowledge from a large community of researchers and industrial practitioners in Software Product Lines (SPLs) gained through extensive and rigorous theoretical, empirical, and applied research. It is a timely compilation of well-established and cutting-edge approaches that can be leveraged by those facing the prevailing and daunting challenge of re-engineering their systems into SPLs. The selection of chapters provides readers with a wide and diverse perspective that reflects the complementary and varied expertise of the chapter authors. This perspective covers the re-engineering processes, from planning to execution. SPLs are families of systems that share common assets, allowing a disciplined software reuse. The adoption of SPL practices has shown to enable significant technical and economic benefits for the companies that employ them. However, successful SPLs rarely start from scratch, but instead, they usually start from a set of existing systems that must undergo well-defined re-engineering processes to unleash new levels of productivity and competitiveness. Practitioners will benefit from the lessons learned by the community, captured in the array of methodological and technological alternatives presented in the chapters of the handbook, and will gain the confidence for undertaking their own re-engineering challenges. Researchers and educators will find a valuable single-entry point to quickly become familiar with the state-of-the-art on the topic and the open research opportunities; including undergraduate, graduate students, and R&D engineers who want to have a comprehensive understanding of techniques in reverse engineering and re-engineering of variability-rich software systems.
