The growth in demand for Internet access and intranet services continues to fuel rapid technical adaptation by both implementers and developers. Unfortunately creating an information resource such as the Internetworking Technology Overview requires a certain recognition by its authors that some information is likely to be obsolete the day it appears in print. The authors of Internetworking Technologies Handbook approached its development with a commitment to helping readers make informed technology decisions and develop a keen awareness of this dilemma. We hope that this first release is a step in the correct direction and that together with other books planned for the Cisco Press program you will be able to identify technologies that will accommodate working network solutions as your requirements change. This chapter discusses the objectives intended audiences and overall organization of the Internetworking Technology Overview Second Edition. Document Objectives This publication provides technical information addressing Cisco-supported internetworking technologies. It is designed for use in conjunction with other Cisco documents or as a stand-alone reference. The Internetworking Technology Overview is not intended to provide all possible information on the included technologies. Because a primary goal of this publication is to help network administrators configure Cisco products the publication emphasizes Cisco-supported technologies however inclusion of a technology in this publication does not necessarily imply Cisco support for that technology. Audience The Internetworking Technology Overview is written for anyone who wants to understand internetworking. Cisco anticipates that most readers will use the information in this publication to assess the applicability of specific technologies for their environments. Organization This publication is divided into eight parts. .
