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.


Dennis Hagarty is an experienced technical specialist in the fields of information technology and telecommunications. He has led presales, consulting, and engineering efforts for major utilities, corporations, and service providers in Australasia and Europe. Having worked in numerous technical areas, Dennis has concentrated on the mobile space for almost 30 years and has specialized in timing and synchronization for the last 12 years. In his current role, Dennis is the Cisco communications interface between engineering, field sales teams, and the global Cisco customer community for all matters related to 5G timing and synchronization. This mandate sees him talking with many large service providers, including most of the world's tier 1 mobile operators.

Shahid Ajmeri is a senior product manager at Cisco with responsibility for leading its 5G transport and mobile edge architecture strategy. He has more than 20 years of experience in the service provider industry, focusing on various technologies ranging from 3G/4G to 5G mobile networks, mobile edge computing, telco data center, service provider security, time synchronization, and end-to-end network design. Shahid has been instrumental in driving network transformation projects and architecting next-generation networks for customers across the globe. He currently works across disciplines, bringing together engineering, standards development organizations, and customers to develop and translate product requirements from industry and standard-setting bodies to the market.

Anshul Tanwar is a principal engineer at Cisco Systems, where he is known as a technologist with a combination of R&D expertise and business sensibility. During his tenure of more than 20 years at Cisco, Anshul has architected many routing and switching products used by large tier 1 mobile and Metro Ethernet service providers across the world. He has led the SyncE and PTP architecture definition and implementation for multiple access and pre-aggregation routers in Cisco. In his most recent role, Anshul was responsible for defining the deployment architecture of phase timing synchronization for one of the world's largest service provider LTE/LTE-A networks. He is also a co-inventor on three patents, including one covering synchronization.
