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)About the Author:
Frank Ohrtman is the president of WMX Systems and the author of several books, including WiMAX Handbook, Wi-Fi Handbook, and Voice Over 802.11. He is a veteran of millions of dollars worth of softswitch request for proposal (RFP) processes from the perspectives of both vendor and buyer.
