Description: IPv6 is the replacement for the currently used IPv4 (Internet Protocol version 4). IPv6 will offer increased IP addresses (full 128-bit addresses, compared to the 32-bit addresses of IPv4), enhanced security, and greater robustness. It will also be fully backwards compatible with existing IPv4 systems. These capabilities will finally make Internet telephony a viable competitor to conventional switched telephone networks. In this book, Dan Minoli clearly explains IPv6 and how telephone networks can be built on its foundations.

This is not just another IPv6 book; instead, it focuses on those aspects of IPv6 relevant to Internet telephony systems and voice networks. Minoli uses a compare/contrast approach, exploring where IPv6 is similar to IPv4 and where it differs, to let you quickly grasp the essence of IPv6 and the similarities (and differences) between current IPv4-based systems and IPv6-based systems.

If you will be designing, implementing, or maintaining the next generation of Internet telephony systems, then you need the information in this book!

*Explains the essential concepts of IPv6 and how they relate to Internet telephony
*Describes how Internet telephony systems using IPv6 are different from, and better than, Internet telephony systems based on the older IPv4 standard
*Discusses how to transition existing IPv4 Internet telephony systems and conventional switched systems to IPv6-based systems
*Extensive treatment of security issues, including IP layer encryption and authentication methods
*Explains connection techniques, including plug and play approaches, for equipment used in IPv6 systems
* The first title describing how the next generation Internet protocolIPv6can be used for Internet telephony
* Explains IPv6 as it applies to Internet telephony (VoIP)
* Shows how IPv6 gives better security, QoS, and signal integrity in Internet telephony.

Description: There is a hidden revolution going on: geography is moving from niche to the mainstream. News reports routinely include maps and satellite images. More and more pieces of equipment cell phones, cars, computers now contain Global Positioning System (GPS) receivers. Many of the major database vendors have made geographic data types standard in their flagship products.

GIS for Web Developers introduces Geographic Information Systems (GIS) in simple terms and demonstrates hands-on uses. With this book, you’ll explore popular websites like maps.google.com, see the technologies they use, and learn how to create your own. Written with the usual Pragmatic Bookshelf humor and real-world experience, GIS for Web Developers makes geographic programming concepts accessible to the common developer.

This book will demystify GIS and show you how to make GIS work for you. You’ll learn the buzzwords and explore ways to geographically-enable your own applications. GIS is not a fundamentally difficult domain, but there is a barrier to entry because of the industry jargon. This book will show you how to “walk the walk” and “talk the talk” of a geographer.

You’ll learn how to find the vast amounts of free geographic data that’s out there and how to bring it all together. Although this data is free, it’s scattered across the web on a variety of different sites, in a variety of incompatible formats. You’ll see how to convert it among several popular formats including plain text, ESRI Shapefiles, and Geography Markup Language (GML).

With this book in hand, you’ll become a real geographic programmer using the Java programming language. You’ll find plenty of working code examples in Java using some of the many GIS-oriented applications and APIs.
