商品描述

Carefully coordinated, reliable, and accurate time synchronization is vital to a wide spectrum of fields—from air and ground traffic control, to buying and selling goods and services, to TV network programming. Ill-gotten time could even lead to the unimaginable and cause DNS caches to expire, leaving the entire Internet to implode on the root servers.

Written by the original developer of the Network Time Protocol (NTP), Computer Network Time Synchronization: The Network Time Protocol on Earth and in Space, Second Edition addresses the technological infrastructure of time dissemination, distribution, and synchronization—specifically the architecture, protocols, and algorithms of the NTP. This system has been active in one form or another for almost three decades on the Internet and numerous private networks on the nether side of firewalls. Just about everything today that can be connected to a network wire has support for NTP.

This book:

  • Describes the principal components of an NTP client and how it works with redundant servers and diverse network paths

  • Provides an in-depth description of cryptographic and other critical algorithms

  • Presents an overview of the engineering principles guiding network configuration

Evaluating historic events that have taken place since computer network timekeeping started almost three decades ago, the author details a number of systems and drivers for current radio, satellites, and telephone modem dissemination and explains how we reckon the time, according to the stars and atoms. The original 16 chapters of the first edition have been rewritten, updated, and enhanced with new material. Four new chapters cover new algorithms and previously uncovered concepts, including timekeeping in space missions.

 

Praise for the first edition:

"… For those that need an exhaustive tome on all of the minutiae related to NTP and synchronization, this is the source. … definitive … this book should be considered the last word on the topic."
—Ben Rothke on Slashdot.org

"… the bible of the subject… contains enough information to take you just as far as you want to go….Dr. Mills is the original developer of NTP."

商品描述(中文翻譯)

小心協調、可靠且準確的時間同步對於廣泛的領域至關重要——從空中和地面交通控制，到商品和服務的買賣，再到電視網絡編程。不正當的時間甚至可能導致難以想像的後果，造成 DNS 快取過期，讓整個互聯網在根伺服器上崩潰。

由網絡時間協議（Network Time Protocol, NTP）的原始開發者撰寫的《計算機網絡時間同步：地球與太空中的網絡時間協議（第二版）》探討了時間傳播、分發和同步的技術基礎設施——特別是 NTP 的架構、協議和算法。這個系統在互聯網及無數私有網絡中以某種形式運行了近三十年。如今，幾乎所有可以連接到網絡線的設備都支持 NTP。

本書：

- 描述 NTP 客戶端的主要組件及其如何與冗餘伺服器和多樣的網絡路徑協同工作
- 提供加密及其他關鍵算法的深入描述
- 概述指導網絡配置的工程原則

評估自近三十年前計算機網絡時間記錄開始以來發生的歷史事件，作者詳細介紹了當前無線電、衛星和電話調製解調器傳播的多個系統和驅動程式，並解釋了我們如何根據星星和原子來計算時間。第一版的原始 16 章已被重寫、更新並增強了新材料。四個新章節涵蓋了新算法和先前未涉及的概念，包括太空任務中的時間記錄。

對於第一版的讚譽：

「……對於那些需要關於 NTP 和同步所有細節的全面著作的人來說，這是唯一的來源。……權威……這本書應被視為該主題的最終權威。」
—Ben Rothke 在 Slashdot.org 上

「……該主題的聖經……包含足夠的信息，可以帶你走到你想去的任何地方……米爾斯博士是 NTP 的原始開發者。」
