内容简介
书籍
计算机书籍
《计算机网络教程:自顶向下方法(英文版)》是计算机领域知名作者Forouzan按照目前计算机网络教学比较流行的自顶向下方法编写的一部重要教材。本书延续了Forouzan一贯的风格，以通俗易懂的方式全面阐述了计算机网络原理及其应用，并介绍了一些目前计算机网络发展的新技术。此外，每章都配有丰富的练习集（包括测试题、练习题、思考题），部分章节还包含仿真实验和编程作业，有助于读者巩固所学知识，提高动手实践能力。
本书特色
协议分层：本书利用Internet协议分层和TCP/IP协议族讲授网络原理，强调各层网络理论之间的相互关系。
自顶向下：从应用层开始，尽早让读者理解网络设备如何工作，然后讨论其他各层，最后介绍物理层。
形象直观：采用图文并茂的方法描述技术性很强的问题，较少涉及复杂的数学公式，便于读者理解相关概念。
举例和应用：以丰富的实例，阐明相关概念，并添加了一些现实中的应用，激发读者的学习热情。

前言
Technologies related to networks and internetworking may be the fastest growing in our culture today. The appearance of some new social networking applications every year is a testimony to this claim. People use the Internet more and more every day. They use the Internet for research, shopping, airline reservations, checking the latest news, weather, and so on.
In this Internet-oriented society, specialists need be trained to mn and manage the Internet, part of the Internet, or an organization's network that is connected to the Internet.This book is designed to help students understand the basics of networking in general and the protocols used in the Internet in particular.
Features
Although the main goal of the book is to teach the principles of networking, it is designed to teach these principles using the following goals:
Protocol Layering
The book is designed to teach the principles of networking by using the protocol layering of the Internet and the TCP/IP protocol suite. Some of the networking principles may have been duplicated in some of these layers, but with their own special details.
Teaching these principles using protocol layering is beneficial because these principles are repeated and better understood in relation to each layer. For example, although addressing is an issue that is applied to four layers of the TCP/IP suite, each layer uses a different addressing format for tifferent purposes. In addition, addressing has a different domain in each layer. Another example is framing and packetizing, which is repeated in several .layers, but each layer treats the principle differently.
Top-Down Approach
Although one of the authors of this book has written several books about networking and the Internet (Data Communication and Networking, TCP/IP Protocol Suite, Cryptography and Network Security, and Local Area Networks), the approach to networking in this book is different. It is a top-down approach.
Although each layer in the TCP/IP protocol suite is built on the services provided by the layer below, there are two approaches to learn about the principles in each layer.In the bottom-up approach, we learn about how bits and signals are moving at the physical layer before learning how applications use these bits to send messages. In the topdown approach, we first learn about how application-layer protocols exchange messages before learning how these messages are actually broken into bits and signals and physically carried through the Internet. In this book, we use the top-down approach.
Audience
This book is written for both academic and professional audiences. The book can be used as a self-study guide for interested professionals. As a textbook, it can be used for a one-semester or one-quarter course. It is designed for the last year of undergraduate study or the first year of graduate study. Although some problems at the end of the chapters require some knowledge of probability, the study of the text needs only general mathematical knowledge taught in the first year of college.
Organization
The book is made of eleven chapters and five appendices.
Chapter 1. Introduction
Chapter 2. Application Layer
Chapter 3. Transport Layer
Chapter 4. Network Layer
Chapter 5. Data-Link Layer: Wired Networks
Chapter 6. Wireless Networks and Mobile IP
