Book Description:
In 1999-2000, VoIP (Voice-over-IP) telephony was one of the most successful buzzwords of the telecom bubble era. However, in 2001-2003, VoIP faced a very tough reality check. Now, manufacturers and service providers are drawing on what they have learnt from past experience in order to prepare to participate in the next major challenge faced by the telecommunications industry.
This book offers a comprehensive overview of the issues to solve in order to deploy global revenue-generating effective “multimedia” services. Drawing on extensive research and practical deployment experience in VoIP, the authors provide essential advice for those seeking to design and implement a post-bubble VoIP network.
Beyond VoIP Protocols: Understanding Voice Technology and Networking Techniques for IP Telephony
* Introduces the basics of speech coding and voice quality
* Demonstrates how quality of service may be built into the network and deals with dimensioning aspects, e.g. multipoint communications and how to model call seizures.
* Explores the potential of multicast to turn an IP backbone into an optimized broadcast medium
* Includes amply illustrated, state-of-the-art practical advice for formulating a complete deployment strategy
A companion volume to “IP Telephony: Deploying VoIP Protocols”, this book takes the reader a stage deeper into how to prepare the network and exploit VoIP technology to its full potential.

Software defined radio (SDR) is a hot topic in the telecommunications field, with regard to wireless technology. It is one of the most important topics of research in the area of mobile and personal communications. SDR is viewed as the enabler of global roaming and a platform for the introduction of new technologies and services into existing live networks. It therefore gives networks a greater flexibility into mobile communications. It bridges the inter-disciplinary gap in the field as SDR covers two areas of development, namely software development and digital signal processing and the internet. It extends well beyond the simple re-configuration of air interface parameters to cover the whole system from the network to service creation and application development. Reconfigurability entails the pervasive use of software reconfiguration, empowering upgrades or patching of any element of the network and of the services and applications running on it. It cuts across the types of bearer radio systems (Paging to cellular, wireless local area network to microwave, terrestrial to satellite, personal communications to broadcasting) enable the integration of many of today’s disparate systems in the same hardware platform. Also it cuts across generation (second to third to fourth). This volume complements the already published volumes 1 and 2 of the Wiley Series in Software Radio. The book discusses the requirements for reconfigurability and then introduces network architectures and functions for reconfigurable terminals. Finally it deals with reconfiguration in the network. The book also provides a comprehensive view on reconfigurability in three very active research projects as CAST, MOBIVAS and TRUST/SCOUT. Key features include: Presents new research in wireless communications Summarises the results of an extensive research program on software defined radios in Europe Provides a comprehensive view on reconfigurability in three very active research projects as CAST (Configurable radio with Advanced Sodftware Technology), MOBIVAS (Downloadable MOBIle Value Added Services through Software Radio and Switching Integrated Platforms), TRUST (Transparently Re-configurable Ubiquitous Terminal) and SCOUT (Smart User-Centric Communciation Environment)

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 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
