作者簡介
Kevin R. Fall博士有超過25年的TCP/IP工作經驗,並且是互聯網架構委員會成員。他是互聯網研究任務組中延遲容忍網絡研究組(DTNRG)的聯席主席,該組緻力於在極端和挑戰性能的環境中探索網絡。他是一位IEEE院士。
W. Richard Stevens博士(1951—1999)是國際知名的Unix和網絡專傢,受人尊敬的技術作傢和谘詢顧問。他教會瞭一代網絡專業人員使用TCP/IP的技能,使互聯網成為人們日常生活的中心。Stevens於1999年9月1日去世,年僅48歲。在短暫但精彩的人生中,他著有多部經典的傳世之作,包括《TCP/IP 詳解》(三捲本)、《UNIX網絡編程》(兩捲本)以及《UNIX環境高級編程》。2000年他被國際專業機構Usenix追授“終身成就奬”。
精彩書評
“我認為本書之所以領先群倫、,是源於其對細節的注重和對曆史的關注。書中介紹瞭計算機網絡的背景知識,並提供瞭解決不斷演變的網絡問題的各種方法。本書一直在不懈努力以獲得精確的答案和探索剩餘的問題域。對於緻力於完善和保護互聯網運營或探究解決長期存在問題的可選方案的工程師,本書提供的見解將是無價的。作者對當今互聯網技術的全麵闡述和透徹分析是值得稱贊的。”
——Vint Cerf, 互聯網先驅
這本書必定是TCP/IP開發人員和用戶的聖經。在我拿到本書並開始閱讀的數分鍾內,我就遇到瞭多個曾經睏擾我的同事及我本人許久的難題,Stevens清晰和明確的闡述讓我豁然開朗。他揭秘瞭此前一些網絡專傢諱莫如深的許多奧妙。我本人參與過幾年TCP/IP的實現工作,以我的觀點,這本書堪稱目前最詳盡的參考書瞭。
——Robert A. Ciampa,3COM公司網絡工程師
《TCP/IP詳解 捲1》對於開發人員、網絡管理員以及任何需要理解TCP/IP技術的人來說,都是極好的參考書。內容非常全麵,既能提供足夠的技術細節滿足專傢的需要,同時也為新手準備瞭足夠的背景知識和相關注解。
