Arrl’s VoIP: Internet Linking for Radio Amateurs

Product Description
*Covers the latest standards and those being developed in an ever-evolving field
*Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry
*Provides an understanding of the true capabilities behind each vendor’s solution to allow for informed buying decisions

A recent survey of 500 U.S. companies with multiple locations found that 81% are planning to implement IP Telephony on their local area networks (LANs) in 2003, and two-thirds are looking at convergence for their wide area networks (WANs) as well. This includes voice, video and data over hard line and wireless networks.
Today, new standards and technologies are being developed to support convergence and voice over IP (VoIP) and Video over IP and wireless. Because convergence covers the voice and data world, it will be critical to understand all of these environments.

Voice, Video, and Data Network Convergence: Architecture and Design, From VoIP to Wireless

Product Description
IPv6 (Internet Protocol version 6) is the future of Internet telephony. And this book is your guide to that future.

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 similariti… More >>
