商品描述

Failure to properly design, implement, and manage it can dramatically reduce mobile network efficiency, reliability and capacity. In 5G environments, time synchronization is even more important to mobile network service providers, and it's also increasingly important to a wide array of emerging applications, from finance to IoT to media. Today's stringent clock accuracy and precision requirements demand deep knowledge and understanding of synchronization protocols, their behavior, and deployment requirements.

In Synchronizing 5G Mobile Networks, three leading Cisco mobile networking technology experts thoroughly address the implementation and characterization of several synchronization standards, presenting practical deployment methods, realistic case studies, and well-tested design best practices. They help engineers and network architects understand the definitions captured in today's synchronization standards and apply them to design deployable solutions.

The authors provide in-depth discussions of key synchronization protocols and profiles including: Synchronous Ethernet standards (G.8262, G.8262.1), 1588v2 Telecom profiles, Precision Time Protocol (PTP) profiles (G.8275.1, G.8275.2), PTP performance profile (G.8273.2), Time sensitive networking (IEEE 802.1CM), GPS or GNSS or PRTC requirements as part of G.8272.x, and security requirements for synchronization protocols. They evaluate the design principle of each profile and performance standard, explains its application in 5G Mobility and Ultra Reliable Low Latency Communications (uRLLC), and help you choose right profiles or protocols for your environment. Detail sections cover network design and migration guidelines, test methodologies and operations and management practices, to help you successfully deploy time synchronization over converged IP networks.

未能正確設計、實施和管理，會大幅降低移動網絡的效率、可靠性和容量。在5G環境中，時間同步對於移動網絡服務提供商尤為重要，對於從金融到物聯網到媒體等各種新興應用也越來越重要。當今嚴格的時鐘準確度和精度要求需要深入了解同步協議、其行為和部署要求。

在《同步5G移動網絡》一書中，三位領先的思科移動網絡技術專家全面介紹了幾個同步標準的實施和特性，提供實用的部署方法、真實的案例研究和經過充分測試的設計最佳實踐。他們幫助工程師和網絡架構師理解當今同步標準中所包含的定義，並應用它們來設計可部署的解決方案。

作者深入討論了關鍵的同步協議和配置文件，包括：同步以太網標準（G.8262、G.8262.1）、1588v2電信配置文件、精密時間協議（PTP）配置文件（G.8275.1、G.8275.2）、PTP性能配置文件（G.8273.2）、時間敏感網絡（IEEE 802.1CM）、作為G.8272.x的一部分的GPS或GNSS或PRTC要求，以及同步協議的安全要求。他們評估了每個配置文件和性能標準的設計原則，解釋了它在5G移動性和超可靠低延遲通信（uRLLC）中的應用，並幫助您選擇適合您環境的配置文件或協議。詳細的章節涵蓋了網絡設計和遷移指南、測試方法和運營管理實踐，以幫助您成功在融合IP網絡上部署時間同步。
