《VoIP技术：应用与挑战2019》是一本由SpringerSeriesinWirelessTechnology系列出版的专业书籍，主要探讨了VoIP（Voice over Internet Protocol）技术在2019年的最新发展、应用及其所面临的挑战。该书由Tamal Chakraborty、Iti Saha Misra和Ramjee Prasad合著，三位作者分别来自Future Institute of Engineering and Management (FIEM)、Jadavpur University和Future Technologies for Business Ecosystem Innovation (FT4BI)。书中深入剖析了VoIP技术的基础架构，特别是在传统和新兴无线通信网络中的应用，如Wi-Fi (WLANs)、WiMAX、LTE和CRN（ Cognitive Radio Network）。这些章节为读者提供了关于如何将VoIP技术融入不同网络环境的实用指导，以及它们之间的协同工作原理。作者详细讲解了关键的呼叫信令协议，包括Session Initiation Protocol (SIP)、H.323和MEGACO，通过对比分析，帮助读者理解这些协议在VoIP通信中的复杂性。通过对QoS（Quality of Service）的全面讨论，涵盖了QoS框架、策略、原则以及衡量VoIP服务质量的重要指标，如延迟、抖动、丢包率（Packet Loss Ratio）、R-factor和Mean Opinion Score (MOS)，这些都直接影响到语音通信的质量和可靠性。本书不仅适合对VoIP技术感兴趣的IT专业人士，还对电信运营商、网络工程师、系统集成商和研究人员具有参考价值。它提供了一个综合的视角，既展示了VoIP技术在当前通信领域的实用性，又揭示了未来可能遇到的技术挑战和改进方向。版权信息显示，这本书受到Springer International Publishing AG的保护，所有权利保留，未经许可不得复制或传播。
