Session Initiation Protocol (SIP) was conceived in 1996 as a signaling protocol for inviting users to multimedia conferences. With this development, the next big Internet revolution silently started. That was the revolution which would end up converting the Internet into a total communication system which would allow people to talk to each other, see each other, work collaboratively or send messages in real time. Internet telephony and, in general, Internet multimedia, is the new revolution today and SIP is the key protocol which allows this revolution to grow.
The book explains, in tutorial fashion, the underlying technologies that enable real-time IP multimedia communication services in the Internet (voice, video, presence, instant messaging, online picture sharing, white-boarding, etc). Focus is on session initiation protocol (SIP) but also covers session description protocol (SDP), Real-time transport protocol (RTP), and message session relay protocol (MSRP). In addition, it will also touch on other application-related protocols and refer to the latest research work in IETF and 3GPP about these topics. (3GPP stands for "third-generation partnership project" which is a collaboration agreement between ETSI (Europe), ARIB/TTC (Japan), CCSA (China), ATIS (North America) and TTA (South Korea).) The book includes discussion of leading edge theory (which is key to really understanding the technology) accompanied by Java examples that illustrate the theoretical concepts.
Throughout the book, in addition to the code snippets, the reader is guided to build a simple but functional IP soft-phone therefore demonstrating the theory with practical examples.
This book covers IP multimedia from both a theoretical and practical point of view focusing on letting the reader understand the concepts and put them into practice using Java. It includes lots of drawings, protocol diagrams, UML sequence diagrams and code snippets that allow the reader to rapidly understand the concepts.
KEY FEATURES
* Focus on HOW multimedia communications over the Internet works to allow readers to really understand and implement the technology
* Explains how SIP works, including many programming examples so the reader can understand abstract concepts like SIP dialogs, SIP transactions, etc.
* It is not focused on just VoIP. It looks At a wide array of enhanced communication services related to SIP enabling the reader put this technology into practice.
* Includes nearly 100 references to the latest standards and working group activities in the IETF, bringing the reader completely up to date.
* Provides a step-by-step tutorial on how to build a basic, though functional, IP soft-phone allowing the reader to put concepts into practice.
* For advanced readers, the book also explains how to build a SIP proxy and a SIP registrar to enhance one's expertise and marketability in this fast moving area.

这本书的封面设计就充满了科技感,仿佛预示着它将带领我们进入一个全新的通信领域。当我翻开第一页,扑面而来的专业术语并没有让我望而却步,反而激发了我探索的欲望。作者的文字功底非常扎实,即使是复杂的概念,也能被他阐述得清晰易懂。他并没有直接灌输知识,而是通过循序渐进的方式,先搭建起通信的基本框架,然后逐步引入SIP协议的核心内容。我尤其喜欢其中关于“信令”的部分,作者用生动的比喻将抽象的信令流程具象化,让我瞬间理解了SIP在多媒体通信中的关键作用。此外,书中对各种通信场景的分析也十分到位,比如VoIP、即时消息、视频会议等等,都结合了SIP协议的实际应用,让我能更直观地感受到SIP的强大之处。虽然我还只是初窥门径,但已经迫不及待地想深入研究下去,去理解那些更深层次的技术细节。
评分这本书的作者显然是一位在互联网多媒体通信领域浸淫多年的专家,他的文字充满了洞察力和前瞻性。我特别喜欢他对SIP协议在网络安全方面的讨论,这部分内容非常关键,但往往容易被忽视。他深入浅出地分析了SIP协议可能面临的各种安全威胁,并提出了相应的应对策略。这种视角让我看到了SIP协议的另一面,它不仅仅是实现通信的工具,更是需要精心设计和保护的系统。此外,书中对SIP在不同平台和设备上的兼容性问题也做了探讨,这对于实际部署和维护项目至关重要。总而言之,这本书提供了一个非常全面的视角,让我能够更深入地理解SIP协议的价值和挑战。
评分这本书给我带来的最大感受是,它不仅仅是一本技术手册,更是一本关于如何构建未来通信桥梁的指南。作者的叙述方式非常灵活,他能够根据不同的技术点,切换不同的讲解风格。有时候是逻辑严谨的分析,有时候是娓娓道来的故事。我尤其喜欢他对SIP作为一种“应用层控制协议”的定位,这让我彻底理解了它在整个互联网通信协议栈中的独特地位。书中还探讨了SIP与WebRTC等新兴技术的结合,为我打开了新的思路。虽然书中没有提供具体的实现代码,但通过作者的文字引导,我已经能够想象出许多复杂的通信场景是如何通过SIP来实现的。这本书让我对互联网多媒体通信充满了信心和期待。
评分这本书的结构设计非常巧妙,它不是一本堆砌事实的教科书,而更像是一场精心策划的知识探索之旅。作者在开篇就为我们描绘了一个宏伟的互联网多媒体通信蓝图,然后一步步地引导我们深入了解SIP协议的内在机制。我特别欣赏他对SIP架构的分解,从核心功能到扩展性,都进行了细致入微的阐述。例如,他对于SIP的注册、邀请、确认以及取消等过程的讲解,都力求严谨,同时又不失趣味性。书中还穿插了一些对未来通信趋势的展望,让我感受到SIP协议强大的生命力和无限的可能性。读这本书,我感觉自己不仅仅是在学习一个技术协议,更是在理解一个不断演进的通信世界。
评分阅读这本书的过程,就像是在一位经验丰富的向导的带领下,穿越一片信息技术的茂密丛林。作者的知识储备深厚,他对互联网多媒体通信的理解,可以说是达到了炉火纯青的地步。他不仅解释了SIP协议本身,还深入剖析了它在整个通信生态系统中的地位,以及与其他相关技术的协同作用。我印象最深刻的是关于“会话建立”的章节,作者详细地讲解了SDP(Session Description Protocol)的工作原理,以及如何通过SIP消息进行媒体参数的协商。这种抽丝剥茧式的讲解方式,让原本可能枯燥的技术细节变得引人入胜。而且,书中还提供了不少实际操作的建议,虽然书中没有包含实际代码,但通过作者的文字引导,我已经能勾勒出很多关键的技术实现步骤,这对于我这样的实践型学习者来说,无疑是极大的帮助。
评分我读过的关于SIP的最好的书。对理解规范来说,一是流程,二是实现,这本书都做得不错,特别是图很多,能帮助理解。
