Digital Communities in a Networked Society: e-Commerce, e-Business and e-Government deals with the accelerating evolution in the computerization of society. This evolution, or should we call it a revolution, is dominantly driven by the Internet, and documented by the novelties introduced, year by year, by Information and Communication Technologies. The book contains recent results of research and development in the areas of: -E-government, -Business models of e-applications, -Innovative structures in the internet, -Auctions and e-payment, -Future aspects of communication, -Internet and the web, -Advanced platforms and grid computing, -Cooperation and integration, -Modeling and construction of e-services.

This is a fully updated revision of Designing Storage Area Networks. It collapses or removes dated material from the original edition and adds new content, particularly in the area of Fibre Channel fabrics, IP SANs and storage virtualization. Storage area networks are now recognized as the preferred solution for fulfilling a wide range of critical data storage needs for institutions and enterprises. The success of SANs in establishing real end-user value is affirmed by the adoption of the technology by all major solution providers as their flagship server and storage offerings. IBM, Hewlett-Packard, Sun, Dell and others now provide certified SAN configurations for performance, high availability and backup of storage data, while storage vendors such as EMC, Hitachi Data Systems, XIOtech...

PRACTICAL ROADMAP FOR DESIGNING AND DEPLOYING A SAN Fibre Channel has come into its own as the defining network architecture for Storage Area Networks (SANs), which are proving critical for managing the volume and complexity of data generated by Internet-era applications. Fibre Channel for SANs, by Dr. Alan F. Benner, shows you how Fibre Channel works, how it integrates with other protocols and systems, and how to implement it to create a SAN for fast access to mass storage. It walks you through the ANSI standard’s 5 levels, from the physical transmission level through interfaces to upper layer protocols, and demonstrates mapping SCSI and IP over Fibre Channel. You get a wealth of timesaving illustrations and practical suggestions for troubleshooting. You learn how to: *Build... Less

Today's enterprises face unprecedented data storage and availability requirements. To meet these needs, they are increasingly turning to Storage Area Networks (SANs). Now, even more promising IP-based SANs are arriving, combining the advantages of SAN architecture with the familiarity and value of IP-based networking. Leading SAN expert Tom Clark surveys these emerging products, helping decision-makers understand the key issues, protocols, technologies, and applications. He begins with an overview of today's enterprise storage challenges and reviews existing approaches, including Fibre Channel, SCSI; and network-attached-s torage solutions. He then introduces IP from the perspective of the storage professional. Clark reviews supporting technologies such as TCP offload engines; and... Less

Frequency Assignment and Network Planning for Digital Terrestrial Broadcasting Systems focuses on Digital Audio Broadcasting and Digital Video Broadcasting. The author provides a concise introduction to the subject and presents principles, concepts and commonly accepted methods used in the planning process. The frequency assignment material focuses on allotment planning while network planning is dealt with mainly from a network optimization perspective. All methods introduced and mathematical tools presented are fully explained. General concepts are illustrated with the help of several planning scenarios both for frequency assignment and network planning. Frequency assignment and network planning are vital issues throughout most of Europe and North America as a direct consequence of the... Less
