SOFTSWITCH DISSECTED
SOFT OR HARD? Hardware switches can cost tens of millions and occupy a city block in real estate. Softswitches are a fraction of the cost and the size of a refrigerator. Bypassing big iron can also make for a more efficient development environment, potentially offering more revenue-generating features than a Class 5 switch. If you want to learn how it's done and what you'll risk, read on.
A key enabling technology for delivering telecom services over the Internet inexpensively, softswitches empower new service providers to compete successfully with incumbents. If we equate "cheaper, smaller, and more convenient to use" with disruptive technology, then softswitch qualifies. But what are the drawbacks, where's the hype, and whose claims can you believe? Now this comprehensive reference to softswitch applications, protocols and platforms gives you an inside look at the software. Frank Ohrtman investigates the technology, the marketplace, and the players, so you can:
* Anticipate how softswitches will affect your systems, services, and vendors
* Learn how to get hardware-level quality, scalability, and signaling from a softswitch
* Evaluate softswitch advantages as Class 4 and Class 5 replacements
* Assess billing capabilities
* Make decisions on signaling protocols
* Compare implementation approaches
* Handle regulatory issues
"The telecommunications industry is now going through a part of a cycle that economist Josef Schumpeter would call 'creative destruction;' legacy infrastructure and business model have gone into decline and must be replaced. This book helps to identify some of the successes and technology challenges..." — Michael H. Khalilian, telecom executive and analyst (from the Foreword)
Editorials
From Barnes & Noble
The Barnes & Noble ReviewSoftswitches are the wave of the telecommunications industry's future! If you want to know more, you should read this excellent book on softswitch technology as the enabling platform for next-generation packet communications -- including voice, broadband, and wireless networks. Franklin D. Ohrtman does an outstanding job of showing how softswitch technology and applications enable global service providers and carriers to optimize their networks and generate new revenue streams with new services and applications. In other words, the author illustrates how softswitch technology disrupts incumbent service providers and their vendors. He helps to identify some of the success and technological challenges of the industry based on the softswitch.
This book focuses on the metrics of performance of the emerging telecommunications infrastructure in terms of scalability, reliability, quality of service (QoS), signaling, and features. Ohrtman analyzes how softswitch technologies might meet or exceed the performance parameters of the Public Switched Telephone Network (PSTN) infrastructure (specifically Class 4 and 5 switches, in addition to Private Branch Exchanges (PBXs). He also explains how it's becoming increasingly clear that Creative Destruction takes place from an engineering perspective. The addition of an acronym list is also a nice touch.
The telecommunications industry is changing, and opportunities abound. Folks who find themselves caught up in this revolution will be delighted with this well-written and coherent account of what's changing and why. Not incidentally, they will also learn how to benefit from these changes. John Vacca
