Designing Large Scale Lans
Publisher: O'Reilly Media
Released: November 2001

This unique book offers a vendor-neutral approach for designing large local area networks according to business or organizational needs, rather than from a product perspective. Author and independent network design consultant Kevin Dooley outlines "top-down network design" for building a technological infrastructure to fit your organization's requirements, a process far more effective and cost-efficient than fitting the organization to the parameters of a shrink-wrapped proprietary solution.

Dooley argues that the design of a network is largely independent of the products used. Whether you use a Cisco or Juniper router, the same security issues and protocols apply. The questions he addresses in this book are need-specific: Do I use a router or a switch? Should I route between switched areas or switch between routed areas?

Designing Large-Scale LANs covers everything from security, bandwidth and scalability to network reliability, which includes backup, redundancy, and points of failure. Specific technologies are analyzed in detail: network topologies, routing and switching strategies, wireless, virtual LANs, firewalls and gateways, security, Internet protocols, bandwidth, and multicast services. The book also discusses proprietary technologies that are ubiquitous, such as Cisco's IOS and Novell's IPX.

This complete guide to top-down network design will help you choose the right network solutions. If you're designing large scale networks and need expert advice and guidance, look no further than Designing Large-Scale LANs.

Aims at the right target but misses wildly

By Matt Simmons

Comments about oreilly Designing Large Scale Lans:

Ideally, I would have marked this two stars, since there was some useful information in this book, but 2 stars was labeled as "average", and this book is below average. In addition to plain out wrong information (see the review regarding STP), the book had a feeling of being thrown together. It was not cohesive, and the information was presented haphazardly. Large sections of useful information was left out and I didn't find a lot of the information pertinent.

I would really like to see a 2nd version of this book come out, properly edited and revised. I feel that most of it would have to be rewritten, but the subject matter is sorely lacking other definitive sources. This book, properly written, would fill a void.

I'm very glad I picked up my copy second hand and thus didn't pay full cover price. If you desire to read it, grab it from the library, and make sure to back up your research in other books. I get the feeling that unless you already know the subject matter well, this book may end up counterproductive.

Designing Large-Scale LANs Review

By Jeff

from Undisclosed

Comments about oreilly Designing Large Scale Lans:

It began by covering basic networking concepts (OSI model, bus/ring/star topologies) but then it hit a harder subject: STP, Spanning Tree Protocol. Here the book failed miserably. The book states that when given two possible paths to root the switch will pick one at random (page 63, last paragraph, "But wait--it gets worse."), which is absolutely incorrect. STP defines a very explicit comparison for choosing one path over another based on the Bridge ID and path cost. Anyway, at that point I had to stop reading for fear of reaching material I did not yet know and then learning something that could be so incorrect.

Designing Large-Scale LANs Review

By David Toye

from Undisclosed

Comments about oreilly Designing Large Scale Lans:

Creating a large scale WAN is not an easy subject to tackle. Dooley's accessible writing style helps the reader to understand the basic concepts first, before explaining higher level counterparts. In this age of CCNA's, MCSE's, and other acronyms, it is refreshing to see a vendor neutral approach to the subject. Not only does he use real world examples, but he shares some of his own experiences and info on best practices, which is invaluable for a network designer.

I found Dooley's use of mathetical equations over the top but I'm sure that there are some geeks out there who would love them. Too bad he did not include some samples of his documentation as an appendix. Overall a decent practical read.

Designing Large-Scale LANs Review

By Charles Hare

from Undisclosed

Comments about oreilly Designing Large Scale Lans:

There isn't an original thought or idea in this book. It is not written for a "Network Designer" as the cover purports, but rather for a Network Novice. Explanations about the OSI model, Basic Topologies, and such don't belong in a book aimed at a higher audience.
