Networking in the Internet Age

ISBN: 978-0-471-20189-2 April 2002 432 Pages


This text is appropriate for those courses with an emphasis on e-commerce and the Internet, as well as short courses or MBA/IS courses that want a modern approach. Networking has changed dramatically over the past ten years. Most texts have focused on network layers and their concepts and then on how the different technologies are implemented; however with the number of viable technologies shrinking, it makes less sense to focus on concepts first and technologies second. Networking in the Internet Age first edition integrates the discussion of concepts and technologies so they appear in one place, organized by layers.

  • Focus on technologies that are in use today in LANs, backbones and the Internet (TCP/IP, web content caching devices, VPNs, wireless LANs). The benefit to students is that they have a shorter book focusing on those technologies that they will be most likely to encounter upon graduation.
  • Organized around the three key layers found in all networks: application, internetwork, hardware. This is an integration of the 7-layer OSI model and the new 3-layer Internet model. This helps students understand the conceptual roles of software and protocols at the different layers (e.g., HTTP, TCP/IP, Ethernet).
  • Best practice recommendations that tie the technical to the managerial. Most books present the facts about the technologies. This book presents the facts and shows how to use them to make better business decisions; that is it shows how to analyze and compare technologies to make sound decisions about which to use where. The analysis methods are explained so they can also be used to fit new technologies not yet developed into the framework so students can decide which new technologies are useful and which are not.
  • Slightly more technical focus. Each of the chapters on the technologies discusses the physical transmission properties and there are more details on TCP/IP (routing, routing protocols). These can be covered in detail for a graduate class, or skimmed over or avoided for an undergraduate class depending upon the focus of the course
