Great Overview of Converged Networks Technlogies
Campus Network Design Fundamentals (ISDN 1-58705-222-9) by Diane Teare and Catherine Paquet is an introductory to mid-level book on converged network design technologies. The book covers a wide range of technologies found in today¿s networks including basic routing and switching, VoIP, wireless, and QoS amongst others. One of the problems with writing such a book is that the list of topics to cover is so large that it is not possible to present any one of them in great detail. As such, the authors have a difficult task of maintaining the balance between too much detail and a glossy, marketing-type of coverage of the topics. In this particular case, the authors manage to tread this fine line with great effectiveness. The topics are covered in good-enough detail to make the material useful and informative for all readers while maintaining balance and cohesiveness in the presentation of all of the topics so as to not lose anyone in the process. The overall organization of the book lends itself to a logical flow of information. It starts with the general design process for building information networks, followed by presentation of technologies used in these networks, and finally ending with practical design examples to illustrate these topics. This allows the reader to grasp the information in a modular fashion, building on the previous knowledge as you progress through the book. The other thing to note is that the authors are not afraid to get into details when such details are necessary. The chapter dealing with QoS is a good example of this. The authors dissect the TOS field in the packet header in some detail. Another example is the VoIP chapter which presents some interesting information about compression schemes and capacity calculations for IP telephony. The final chapters present a case study where all of the previously learned concepts are put to use in designing a network for a hypothetical firm. These chapters translate into an excellent summary of the material presented in the previous chapters. Experienced readers may find some of the information in the book to be introductory but that is due to the nature of the material being presented. For example, the information relating to switching and routing is basic due to the fact that it is a well established technology and most people working in the networking arena are experienced with it. VoIP on the other hand is new and as such may come across as new information. To the authors¿ credit, they present the more well-known topics before the less well-known ones. This book should serve as a good, solid primer on converged network technologies. Within the past couple of years, networking technology is making a concerted shift towards unification of communication needs including voice, data, and video. This book presents a comprehensive overview of the technologies used to make this shift possible. I highly recommend this to anyone involved in designing, implementing, or managing converged networks.Was this review helpful? Yes NoThank you for your feedback.
