商品描述

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 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 (from the Foreword)

軟交換解析

SOFT OR HARD?
硬體交換器的成本可能高達數千萬，佔據一個城市街區的地盤。軟交換器的成本和體積只有冰箱的一小部分。繞過大型設備還可以創造一個更高效的開發環境，可能提供比5級交換器更多的收入生成功能。如果您想了解如何實現以及可能面臨的風險，請繼續閱讀。

作為以低成本在互聯網上提供電信服務的關鍵技術，軟交換器使新的服務提供商能夠成功與現有的提供商競爭。如果我們將更便宜、更小巧和更方便使用與破壞性技術相提並論，那麼軟交換器就符合這一標準。但是它有什麼缺點，宣傳在哪裡，誰的聲稱可以相信？現在，這本關於軟交換器應用、協議和平台的全面參考資料將讓您深入了解軟體。Frank Ohrtman調查了技術、市場和參與者，因此您可以：

* 預測軟交換器對您的系統、服務和供應商的影響
* 學習如何從軟交換器獲得硬體級的質量、可擴展性和信令
* 評估軟交換器作為4級和5級交換器替代品的優勢
* 評估計費能力
* 在信令協議上做出決策
* 比較實施方法
* 處理監管問題

"電信行業現在正在經歷經濟學家約瑟夫·熊彼特稱之為創造性破壞的一部分循環；傳統基礎設施和商業模式已經衰退，必須被替換。這本書有助於確定一些成功和技術挑戰..." - Michael H. Khalilian，電信執行官和分析師（來自前言）
