精彩书摘

Before we start to examine the technical issues in detail, it is worth devotingsome time to pointing out why people are interested in computer networks andwhat they can be used for.After all, if nobody were interested in computer net-works,few of them would be built. We will start with traditional uses at com-panies,then move on to home networking and recent developments regardingmobile users, and finish with social issues.1.1.1 usiness Applications Most companies have a substantial number of computers. For example, acompany may have a computer for each worker and use them to design products,write brochures, and do the payroll.Initially, some of these computers may haveworked in isolation from the others, but at some point, management may havedecided to connect them to be able to distribute information throughout the com-pany.

前言/序言

　 PREFACE

　 This book is now in its fifth edition. Each edition has corresponded to a different phase in the way computer networks were used. When the first edition appearedin 1980, networks were an academic curiosity. When the second edition appeared in 1988, networks were used by universities and large businesses. When the third edition appeared in 1996, computer networks, especially the Internet, had become a daily reality for millions of people. By the fourth edition, in 2003, wireless networks and mobile computers had become commonplace for accessing the Web and the Internet. Now, in the fifth edition, networks are about content distribution(especially videos using CDNs and peer-to-peer networks) and mobile phones are small computers on the Internet.

　 Among the many changes in this book, the most important one is the addition f Prof. David J. Wetheall as a co-author. David brings a rich background in networking,having cut his teeth designing metropolitan-area networks more than 20years ago. He has worked with the Internet and wireless networks ever since and is a professor at the University of Washington, where he has been teaching and doing research on computer networks and related topics for the past decade.

　 Of course, the book also has many changes to keep up with the: ever-changing world of computer networks. Among these are revised and new material on Wireless networks (802.12 and 802.16)

　 The 3G networks used by smart phones

　 RFID and sensor networks

　 Content distribution using CDNs

　 Peer-to-peer networks

　 Real-time media (from stored, streaming, and live sources)

　 Internet telephony (voice over IP)

　 Delay-tolerant networks

　 A more detailed chapter-by-chapter list follows.

　 Chapter 1 has the same introductory function as in the fourth edition, but the contents have been revised and brought up to date. The Internet, mobile phone networks, 802.11, and RFID and sensor networks are discussed as examples of computer networks. Material on the original Ethernet—with its vampire taps—has been removed, along with the material on ATM.

　 Chapter 2, which covers the physical layer, has expanded coverage of digital modulation (including OFDM as widely used in wireless networks) and 3G networks (based on CDMA). New technologies are discussed, including Fiber to the Home and power-line networking.

　 Chapter 3, on point-to-point links, has been improved in two ways. The material on codes for error detection and correction has been updated, and also includes a brief description of the modern codes that are important in practice (e.g., convolutional and LDPC codes). The examples of protocols now use Packet over SONET and ADSL. Sadly, the material on protocol verification has been removed as it is little used.

　 In Chapter 4, on the MAC sublayer, the principles are timeless but the technologies have changed. Sections on the example networks have been redone accordingly, including gigabit Ethernet, 802.11, 802.16, Bluetooth, and RFID.

　 Also updated is the coverage of LAN switching, including VLANs.

　 Chapter 5, on the network layer, covers the same ground as in the fourth edition.

　 .　　The revisions have been to update material and add depth, particularly for quality of service (relevant for real-time media) and internetworking. The sections on BGP, OSPF and CIDR have been expanded, as has the treatment of multicast routing. Anycast routing is now included.

　 Chapter 6, on the transport layer, has had material added, revised, and removed.

　 New material describes delay-tolerant networking and congestion control in general. The revised material updates and expands the coverage of TCP congestion control. The material removed described connection-oriented network layers, something rarely seen any more.

　 Chapter 7, on applications, has also been updated and enlarged. While material on DNS and email is similar to that in the fourth edition, in the past few years there have been many developments in the use of the Web, streaming media and content delivery. Accordingly, sections on the Web and streaming media have been brought up to date. A new section covers content distribution, including CDNs and peer-to-peer networks.

　 Chapter 8, on security, still covers both symmetric and public-key cryptography for confidentiality and authenticity. Material on the techniques used in practice, including firewalls and VPNs, has been updated, with new mater 经典原版书库：计算机网络（英文版·第5版） [Computer Networks, Fifth Edition] 下载 mobi epub pdf txt 电子书格式
