SIP Demystified

ASSESS WHAT SIP CAN DO AND DELIVER

EVALUATE SIPs FIT WITH OTHER STANDARDS AND SYSTEMS

PLAN NEW SIP-ENABLED SERVICES

The Session Initiation Protocol (SIP) is the signalling protocol that will deliver IP multimedia services for the third generation of mobile systems. It will merge together the cellular and Internet worlds. It will provide ubiquitous access to the services it enables, and make us a truly mobile population for the first time. These are not small claims, which might explain why some people have started looking to SIP as an all-purpose solution to building the telecom future.

In fact, SIP is a powerful but limited protocol, with a well-defined scope. This book describes it in the context its framers intended, and meticulously explains how to use it as a transformative tool for telecom services. Written by one of the earliest contributors to SIP development in the IETF, SIP DEMYSTIFIED takes a long look at the whats and whys of todays most talked-about protocol, helping readers to move past the buzz, get poised for 3G, and start developing tomorrows applications.

You must read this book if--

* Youre a telecom engineer, manager, or developer who wants to survive professionally in a converged world

* You want a smooth transition from switched circuits to the connectionless paradigm

* You want to be first to market with SIP services

* You want to know how SIP interacts with other protocols

* You need to find out what architectures support SIP

* You have questions about QoS, security, and authentication

* You want to evaluate SIP products, such as gateways, proxy servers, application servers, SIP phones, instant messaging, and presence applications

* Youre an industry analyst predicting and rating coming hot products and services

* Youre a curious noncombatant who cant get enough insider details on how the newest technologies work

SIP DEMYSTIFIED gives you jargon-free explanations of the concepts that set SIP apart from other protocols and the reasons the standard was drafted--so you can decide what to do with it.

在廣泛的通訊背景中了解SIP
評估SIP的功能和傳遞能力
評估SIP與其他標準和系統的適配性
計劃新的SIP啟用服務

會話初始化協議（SIP）是為第三代移動系統提供IP多媒體服務的信令協議。它將融合蜂窩和互聯網世界，為其啟用的服務提供無處不在的訪問，使我們首次成為真正的移動人口。這些都不是小小的聲稱，這可能解釋了為什麼有些人開始將SIP視為建立電信未來的萬能解決方案。

事實上，SIP是一個功能強大但有限的協議，具有明確的範圍。本書描述了SIP的原始意圖，並詳細解釋了如何將其用作電信服務的轉型工具。本書的作者是IETF中最早的SIP開發貢獻者之一，SIP DEMYSTIFIED深入探討了當今最為人津津樂道的協議的內容和原因，幫助讀者超越噪音，為3G做好準備，並開始開發明天的應用程序。

如果您是以下人士，您必須閱讀本書：
- 想在融合的世界中在專業上生存的電信工程師、經理或開發人員
- 想要從交換電路平台平滑過渡到無連接範式
- 想要率先推出SIP服務
- 想要了解SIP與其他協議的互動方式
- 需要了解支持SIP的架構
- 對QoS、安全性和身份驗證有疑問
- 想要評估SIP產品，如網關、代理服務器、應用服務器、SIP手機、即時通訊和在線狀態應用程序
- 是預測和評估即將推出的熱門產品和服務的行業分析師
- 是一個好奇的閒雲旁觀者，對最新技術的內幕細節趨之若鶩

SIP DEMYSTIFIED以不帶行話的方式解釋了將SIP與其他協議區分開來的概念，以及制定該標準的原因，讓您可以決定如何使用它。
