Présentation de l'éditeur

In 2002 voice over IP will constitute more than 25% of all long distance voice calls, according to Network World. That’s more than a 30% ramp-up from 2001. The emergence of SIP, MPLS and new quality of service tools is making carrier grade voice over IP a service reality, and a potentially huge margin booster and revenue driver for service providers.The first edition of Carrier Grade Voice over IP played a roll in VoIP growth, in less than year becoming an essential tool for carriers working to provide high quality IP telephony. This new edition vastly updates the SIP chapter, details MPLS, and takes the explanations of the previous edition a step further in a final chapter that shows, step by step, how to design working VoIP networks. --Ce texte fait référence à une édition épuisée ou non disponible de ce titre.

Quatrième de couverture


In the race to put carrier-quality voice over IP (VoIP)——those using this book run faster and falter less. International expert Daniel Collins’ greatly enhanced Carrier Grade Voice over IP brings you leading-edge signaling schemes, protocol apps, and quality of service (QoS) techniques—and more importantly, the answers to making them work together.

Skipping needless history, chitchat, and math, Collins gets right down to solutions with solid information on protocols’ purposes and uses. He gives you the newest information with hands-on details, showing you how to:

* Use ITU and IETF protocols to build next-generation networks
* Enable advanced features and services, including expanded SIP coverage
* Provide wireline-quality service with resource reservation schemes and QoS techniques, including the latest information on MPLS advances
* Overcome limitations inherent in IP
* Seamlessly interwork VoIP systems with traditional telephony networks
* Design real-world VoIP networks (new chapter)
* Pull the pieces together into a system that works—and does not break

Complete with numerous specific examples of how the protocols are used and integrated, this just-in-time guide supplies the solutions you need to roll out competitive quality VoIP.

Jumpstart carrier-quality VoIP with help from international expert Daniel Collins --Ce texte fait référence à une édition épuisée ou non disponible de ce titre.

Very much self contained 10 février 2001
Par Kalyan Sannedhi - Publié sur Amazon.com
Format: Broché
Great book on VoIP, still emerging technology. It did a great job in explaining concepts related to QoS such as RSVP, DiffServ and MPLS. Right from basics such as IP, UDP, TCP and various coding techniques you will find great explanation to each and every item. If you are interested in knowing about VoIP or you if u wanna work on VoIP this is the ONLY book you need. There is very detailed and neat explanation related to MGCP, MEGACO, SS7 and SIP too. The only thing that i felt lacking is testing of voice quality both subjective and objective and how they could be done. No doubt in giving 5 *s to it, great job!

Excellent 8 janvier 2001
Par Tom Howard - Publié sur Amazon.com
Format: Broché
Aimed specifically at designers of public telecommunications networks, this easy to read book provides practical and useful hands-on information. Where necessary, topics are covered in great detail. For example, 120 pages are dedicated to H.323. Softswitch architecture and programming are covered, and 55 pages are devoted to discussing Quality of Service issues.
We believe this book to be an essential read, and recommend it highly.

Great explanation of the latest VoIP technology 28 octobre 2000
Par John McCarthy - Publié sur Amazon.com
Format: Broché
Daniel Collins has done a great job of explaining the latest VoIP technology. He uses a lot of call flow diagrams, which I find particularly useful in understanding how the various protocols work. In addition, his writing style is very clear, such that he makes it easy to understand what he is talking about. Not only does he address the most recent developments in the technology (eg. SIP, MGCP, MEGACO), he also does a good job of explaining how these technologies can fit with what is already in place (eg. H323 as well as traditional networks). In this regard, the chapter concerning SS7 is useful, although some focus on TALI as well as Sigtran would have been beneficial. - Overall, a good book that I would recommend to anyone who wants to understand VoIP.

VOIP for Techs and Execs Alike 23 octobre 2000
Par Un client - Publié sur Amazon.com
Format: Broché
Daniel Collins has written a terrific reference for anyone interested in understanding Voice Over IP. From the very start of the book, it is clear that Collins has the ability to address key areas of interest for technical readers, planners, and executives. Readers with a techincal interest should be very comfortable using this book as their reference for all key issues and questions related to the emerging opportunity of VOIP. Congratulations to Mr. Collins for his eloquent and well organized description of VOIP for anyone trying to understand and/or exploit this emerging communications opportunity.

Format: Broché Achat vérifié
Collin's book provides a simple straight forward review of Voice over IP. If you need to understand SIP, H.323, Megaco, or Softswitches this book is a must.
