Explores the technological infrastructure of time dissemination, distribution, and synchronization. This book addresses the architecture, protocols, and algorithms of the Network Time Protocol (NTP) and discusses how to identify and resolve problems encountered in practice.

Mills demonstrates the algorithms used to select measurements accessed via diverse pathways to achieve the best accuracy, addresses security issues in depth, and describes the engineering principles underlying NTP architecture and timestamping exchange procedures. Opening the door to highly precise time synchronization in both public and private networks, "Computer Network Time Synchronization" offers in-depth analysis, theory, and practical concerns in a unified and authoritative reference.
