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)

精心協調、可靠且準確的時間同步對於廣泛的領域至關重要,從空中和地面交通管制,到買賣商品和服務,再到電視網絡節目。不正當獲得的時間甚至可能導致難以想像的後果,並導致 DNS 快取過期,使整個互聯網在根服務器上崩潰。

《計算機網絡時間同步:地球和太空中的網絡時間協議,第二版》是網絡時間協議(NTP)的原始開發者撰寫的,該書探討了時間傳播、分發和同步的技術基礎,具體包括 NTP 的架構、協議和算法。這個系統在互聯網上以各種形式活躍了將近三十年,並在防火牆的另一側的眾多私有網絡上運行。如今,幾乎所有可以連接到網絡線的東西都支持 NTP。

本書包括以下內容:
- 描述 NTP 客戶端的主要組件以及它如何與冗余服務器和多樣化的網絡路徑一起工作
- 提供對加密和其他關鍵算法的深入描述
- 概述指導網絡配置的工程原則

作者詳細評估了自從計算機網絡時間記錄開始以來發生的歷史事件,並解釋了目前的無線電、衛星和電話調制解調器傳播的系統和驅動程序,以及我們如何根據星星和原子計算時間。第一版的原始16章已經重寫、更新並增加了新的材料。四個新章節涵蓋了新的算法和以前未涉及的概念,包括太空任務中的時間記錄。

第一版的讚譽:
「……對於那些需要一本關於NTP和同步的詳盡著作,這是最好的來源……權威性……這本書應該被視為該主題的最終指南。」—Ben Rothke 在 Slashdot.org 上的評論
「……這是該主題的聖經……包含足夠的信息,讓您達到所需的任何程度……Mills 博士是 NTP 的原始開發者。」—Books On-Line 上的評論
