Although several books and academic courses discuss data management and networking, few of them focus on the convergence of networking and software technologies for identifying, addressing, and managing distributed data. Focusing on this convergence, Identification and Management of Distributed Data: NGN, Content-Centric Networks and the Web collates and describes the various distributed data management technologies to help readers from various backgrounds understand the common aspects that govern distributed data management. With a focus on the primary problems in identifying, addressing, and managing information in a distributed environment, the book guides you through the discovery of distributed data management on the web, in next-generation networks (NGNs), and in new content-centric networking paradigms. It includes case studies from the Palo Alto Research Center and the Semantic Web Education and Outreach Interest Group that illustrate the convergence between software engineering and networking technologies. Derived from academic courses, ongoing research, and the latest standardization initiatives, the book explains how the various layers of the existing Internet protocol stack already provide most of the functions that information engineers need to design efficient systems. Although the subject is broad, the book provides helpful insights into a number of critical technologies to provide you with the foundation required to build and deploy more efficient data interoperability paradigms in next-generation networks.

Following on from Rob Davis’ successful introductory book, ARIS Design Platform: Getting Started with BPM, Rob now covers in detail some of the more advanced concepts of using ARIS Business Architect. This is a practical ‘how-to’ guide and contains tips, techniques and short cuts gained from practical experience and explains clearly how to use ARIS and why ARIS is a powerful tool for process modeling. Advanced concepts such as the following are presented in this reader-friendly and concise guide: - Matrix editor, - Find and query, - Model generation, - Method filters and method changes, - Templates and fonts, - Reports and semantic checks, - Macros, - Transformations, - Database administration, - User management. This easy-to-follow advanced text is a must have guide and reference for all users who want to increase their ARIS skills, and for those who need to undertake advanced model and database management.

HTTP is the protocol that powers the Web. As Web applications become more sophisticated, and as emerging technologies continue to rely heavily on HTTP, understanding this protocol is becoming more and more essential for professional Web developers. By learning HTTP protocol, Web developers gain a deeper understanding of the Web's architecture and can create even better Web applications that are more reliable, faster, and more secure. The HTTP Developer's Handbook is written specifically for Web developers. It begins by introducing the protocol and explaining it in a straightforward manner. It then illustrates how to leverage this information to improve applications. Extensive information and examples are given covering a wide variety of issues, such as state and session management, caching, SSL, software architecture, and application security.

This comprehensive volume provides state-of-the art guidance on Quality of Service (QoS) and Quality of end-user Experience (QoE) management in UMTS cellular systems, tackling planning, provisioning, monitoring and optimisation issues in a single accessible resource. In addition, a detailed discussion is provided on service applications, QoS concept, architecture and functions in access, packet & circuit switched core and backbone networks. Defines and explains the differences between QoS and QoE, and end-to-end concept, based on the premise that it is the end-user who is the ultimate beneficiary of QoS. Covers QoS and QoE issues related to present and forthcoming service applications, including multimedia messaging service (MMS), Video Sharing (VS), content download, business connectivity, Push to talk over Cellular (PoC), Voice over IP (VoIP), presence, instant messaging, gaming, streaming and browsing. Presents QoS concepts and architecture as defined in 3GPP Releases 97/98, 99, 5, 6, and 7, and provides a comprehensive description of protocols and packet data transfer across WCDMA evolved and (E)GPRS networks. Discusses service driven radio network planning aspects for (E)GPRS and WCDMA. Includes three detailed chapters covering concepts, means and methods for QoS provisioning, QoS & QoE performance monitoring and optimisation. This book is aimed at operators, vendors, deployers, consultants and managers specialising in the research, development, implementation, marketing and sales of products and tools for QoS and QoE management in UMTS networks. It will also be of interest to postgraduate students and researchers in the field of telecommunications and specialising in UMTS QoS and QoE principles and practices.
