The remainder of the book deals with fast IP address lookup. Coverage includes the various available architectures, data structures, and algorithms based on software and hardware as well as detailed discussions on state-of-the-art innovations. With many illustrations, tables, and simulations, this practical guide to packet forwarding technologies facilitates understanding of IP routers and the latest router designs.

The final chapter discusses the features required for efficient implementation of asynchronous iterative algorithms. Providing the theoretical and practical knowledge needed to design and implement efficient parallel iterative algorithms, this book illustrates how to apply these algorithms to solve linear and nonlinear numerical problems in parallel environments, including local, distant, homogeneous, and heterogeneous clusters.

Recognizing that most programmers will ultimately be applying these techniques in an object-oriented programming (OOP) context, Gill adopts a programming style (e.g., use of very small functions, dividing projects into separate files, creating functions to perform specific operations on structures) that fits nicely with typical OOP approaches.

Press On provides the insights, concepts and programming tools to improve usability. Knowing the computer science is fundamental, but Press On also shows how essential it is to have the right approaches to manage the design of systems that people use. Particularly for complex systems, the social, psychological and ethical concerns–the wider design issues–are crucial, and these are covered in depth. Press On highlights key principles throughout the text and provides cross-topic linkages between chapters and suggestions for further reading. Additional material, including all the program code used in the book, is available on an interactive web site. Press On is an essential textbook and reference for computer science students, programmers, and anyone interested in the design of interactive technologies.

Drawing on extensive research and practical development experience in VoIP from its earliest stages, the authors give access to all the relevant standards and cutting-edge techniques in a single resource.

IP Telephony: Deploying Voice-over-IP Protocols:

• Assumes a working knowledge of IP and networking and addresses the technical aspects of real-time communication over IP.
• Presents a high level overview of packet media transport technologies, covering all the major VoIP protocols – SIP, H323 and MGCP
• Details specific strategies to design services for public networks where endpoints cannot be trusted and can be behind firewalls.
• Explores the problems that may arise from incomplete protocol implementations, or architectures optimized for private networks which fail in a public environment.

This amply illustrated, state-of-the art reference tool will be an invaluable resource for all those involved in the practical deployment of VoIP technology.

Among the first books to present information on interprovider communications and interconnection of IP telephony clouds, the text supplies a clear and up-to-date picture of the VoIP protocol jungle.

• Provides detailed guidance on how to implement VoIP interconnect services
• Presents an overview of deployed architectures in fixed and mobile networks used for interconnection and roaming purposes
• Enumerates regulatory issues with a focus on Europe and the United States
• Proposes interconnection models
• Suggests viable solutions to technical issues

This reference supplies an overview of interconnection practices in PSTN/mobile. It proposes solutions for overcoming service engineering issues and includes a set of recommendations to ease the proliferation of interconnection agreements and schemes. Keeping you up to speed with recent developments in IP telephony, the book facilitates the understanding of the technical and regulatory requirements needed to provide global services to your customers and successfully navigate the upcoming migration to a completely IP-based model.

“Agile Software Development is a highly stimulating and rich book. The author has a deep background and gives us a tour de force of the emerging agile methods.”

Each major topic is organised into two chapters, beginning with basic concepts that provide necessary background for understanding each data mining technique, followed by more advanced concepts and algorithms.
