Samenvatting
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 contemporary 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.
