Networking

Second Edition

 

Jeffrey S. Beasley

 

This text provides a comprehensive look at computer networking from the point of view of the network administrator. It guides readers from an entry-level knowledge in computer networks to advanced concepts in Ethernet networks; router configuration; TCP/IP networks; local-, campus-, and wide-area network configuration; network security; optical networks; voice over IP; and industrial networks. Extensive examples on the Windows Server 2003/2008 configuration and system configuration for the Linux operating system are also included. A complete chapter is devoted to protecting and securing a network from potential network attacks. Topics include denial of service attacks, firewalls, intrusion detection, password cracking, packet sniffing, and analyzing unsecured data packets. Other key network security issues, such as configuring router access lists, configuring a virtual private network (VPN) connection, and securing wireless networks, are also covered. Router configuration is examined, ranging from an introduction to router configuration to configuring multiple routing protocols for intranet and Internet data traffic. Routing protocols key to basic network operations are examined, including static, RIP, IGRP, OSPF, EIGRP, and BGP. The discussions on routing protocols are accompanied with in-depth steps for configuring the router to run the protocol, verify operation, and troubleshoot the router.

 

Key Pedagogical Features

NET-CHALLENGE SOFTWARE provides a simulated, hands-on experience in configuring routers and switches. Exercises provided in the text and on the CD challenge readers to undertake certain router/switch network configuration tasks. The software has the look and feel of actually being connected to the router or switch console port. PROTOCOL ANALYZER SOFTWARE included with the text uses the Finisar Surveyor Demo. Examples of using the software to analyze data traffic are included throughout the text. ACCOMPANYING CD-ROM includes the Finisar Surveyor Demo software and captured data traffic used in the text, which enables readers to capture data traffic on their own networks. CONFIGURING, ANALYZING, or TROUBLESHOOTING sections are included with each chapter to guide the reader through advanced techniques in networking. OBJECTIVES and INTRODUCTION at the beginning of each chapter clearly outline specific goals for the reader. EXTENSIVE PROBLEM SETS, SUMMARIES, and QUESTIONS AND PROBLEMS (including Critical Thinking questions) are found at the end of each chapter. KEY TERMS and their definitions are highlighted in the margins to foster inquisitiveness and ensure retention.

Networking, Second Edition Preface This book provides a comprehensive look at computer networking from the point of view of the network administrator. It guides readers from an entry-level knowledge in computer networks to advanced concepts in Ethernet networks, router configuration, TCP/IP networks, routing protocols, local, campus, and wide area network configuration, network security, wireless networking, optical networks, Voice over IP, the network server, Linux networking, and industrial networks. After covering the entire text, readers will have gained a solid knowledge base in computer networks. In my years of teaching, I have observed that technology students prefer to learn "how to swim" after they have gotten wet and taken in a little water. Then they are ready for more challenges. Show the students the technology, how it is used, and why, and they will take the applications of the technology to the next level. Allowing them to experiment with the technology helps them to develop a greater understanding. This book does just that. Organization of the Text This text is designed to cover two semesters. The recommended chapters for the first semester are Chapters 1 to 8. Throughout the semester, the students will gain an appreciation of how basic computer networks and related hardware are interconnected to form a network. This involves understanding the concepts and issues of twisted-pair cable, interconnecting LANs, configuring TCP/IP, subnet masking, basic router configuration, and configuring routing protocols and wide area networking. Chapters 9 to 16 are recommended for the second semester--configuring and managing the campus network, network security, wireless LANs, and optical networks. The instructor can choose from the following topics to complete the semester: installing and configuring Windows 2008/2003 network server, Voice over IP, Linux configuration, and industrial networks. Key Pedagogical Features Chapter Outline, Objectives, Key Terms, and Introduction at the beginning of each chapter clearly outline specific goals for the reader. An example of these features is shown in Figure P-1. Net-Challenge Software provides a simulated, hands-on experience in configuring routers. Exercises provided in the text (see Figure P-2) and on the CD challenge readers to undertake certain router/network configuration tasks. The challenges check the students' ability to enter basic networking commands and to set up router function, such as configuring the interface (Ethernet and Serial) and routing protocols (that is, OSPF, BGP, EIGRP, IGRP, RIP, and static). The software has the look and feel of actually being connected to the router's console port. Protocol Analyzer Software packaged with the text uses the Finisar Surveyor Demo. Examples of using the software to analyze data traffic are included throughout the text, as shown in Figure P-3. Numerous worked-out examples are included in every chapter to reinforce key concepts and aid in subject mastery, as shown in Figure P-3. Configuring, Analyzing, or Troubleshooting sections, as shown in Figure P-4, are included with each chapter to guide the reader through advanced techniques in networking. Key Terms and their definitions are highlighted in the margins to foster inquisitiveness and ensure retention. This is illustrated in Figure P-5. Extensive Summaries, Questions, and Problems as well as Critical Thinking Questions are found at the end of each chapter, as shown in Figure P-6. An extensive Glossary is found at the end of the book and offers quick, accessible definitions to key terms and acronyms, as well as an exhaustive Index (Figure P-7). Accompanying CD-ROM The CD-ROM packaged with the text includes the Finisar Surveyor Demo software and captured data traffic used in the text. This software provides readers with the opportunity to capture data traffic on their own network. It also includes the Net-Challenge Software, which was developed specifically for this text. Instructor Resources The Instructor's Manual to accompany Networking, Second Edition (ISBN 0-13-135838-3) provides the entire book in PDF format along with instructor notes for each section within each chapter, recommending key concepts that should be covered in each chapter. Solutions to all chapter Questions and Problems sections are also included. In addition, the instructor will find a separate Solutions to the Net-Challenges Instructor's Edition PDF as well as a 18 laboratory exercises. Also a test bank with which to generate quizzes on the material found within the student edition of the book is provided. (c) Copyright Pearson Education. All rights reserved.
