商品描述
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 its
done and what youll 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, wheres 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
