Guide to OSI and TCP/IP Models (SpringerBriefs in Computer Science)

This work opens with an accessible introduction to computer networks, providing general definitions of commonly used terms in networking. This is followed by a detailed description of the OSI model, including the concepts of connection-oriented and connectionless communications. The text carefully elaborates the specific functions of each layer, along with what is expected of protocols operating at each layer. Next, the journey of a single packet, from source to destination, is described in detail. The final chapter is devoted to the TCP/IP model, beginning with a discussion of IP protocols and the supporting ARP, RARP and In ARP protocols. The work also discusses the TCP and UDP protocols operating at the transport layer and the application layer protocols HTTP, DNS, FTP, TFTP, SMTP, POP3 and Telnet. Important facts and definitions are highlighted in gray boxes found throughout the text.

這本書以一個易於理解的介紹開始，介紹了計算機網絡的基本概念，並提供了網絡中常用術語的一般定義。接著，詳細描述了OSI模型，包括連接導向和無連接通信的概念。本書詳細闡述了每一層的具體功能，以及在每一層上運行的協議所期望的工作。接下來，詳細描述了一個單個封包從源頭到目的地的旅程。最後一章專門介紹了TCP/IP模型，從IP協議和支持的ARP、RARP和In ARP協議開始討論。本書還討論了在傳輸層上運行的TCP和UDP協議，以及應用層協議HTTP、DNS、FTP、TFTP、SMTP、POP3和Telnet。重要的事實和定義在全書中以灰色方框突出顯示。
