商品描述

"Computer Networks, 4/e" is the only introductory computer networking book written by authors who have had first-hand experience with many of the protocols discussed in the book, who have actually designed some of them as well, and who are still actively designing the computer networks today. This newly revised edition continues to provide an enduring, practical understanding of networks and their building blocks through rich, example-based instruction. The authors' focus is on the why of network design, not just the specifications comprising today's systems but how key technologies and protocols actually work in the real world to solve specific problems. The new edition makes less use of computer code to explain protocols than earlier editions. Moreover, this new edition shifts the focus somewhat higher in the protocol stack where there is generally more innovative and exciting work going on at the application and session layers than at the link and physical layers. It is completely updated with new sidebars discussing successes/failures of previously deployed networks. It features thorough companion website with downloadable OpNet network simulation software and lab experiments manual. It includes expanded coverage of topics of utmost importance to today's networking professionals, e.g., security, wireless, multimedia applications.

商品描述(中文翻譯)

《計算機網絡,第四版》是唯一一本由有第一手經驗的作者撰寫的入門級計算機網絡書籍,這些作者不僅親自參與了書中討論的許多協議,還設計了其中一些協議,並且至今仍在積極設計計算機網絡。這本新修訂版通過豐富的基於實例的教學,持續提供對網絡及其構建模塊的持久實用理解。作者的重點在於網絡設計的原因,不僅僅是當今系統的規範,還包括關鍵技術和協議在現實世界中如何解決特定問題。新版相比之前的版本在解釋協議時使用的計算機代碼更少。此外,這本新版將焦點稍微放在協議堆疊的較高位置,因為在應用層和會話層通常有更多創新和令人興奮的工作,而不是在鏈路層和物理層。它完全更新,附有討論先前部署的網絡成功/失敗的新側邊欄。它還具有全面的附帶網站,可下載OpNet網絡模擬軟件和實驗室實驗手冊。它還擴展了對當今網絡專業人士極為重要的主題的涵蓋,例如安全性、無線技術和多媒體應用。
