2starsBetter off choosing an alternative selection

As IS-IS is one of the more esoteric protocols, understood only by a few people in large scale ISP environments, I thought this book would be a welcome addition to my library as there isn’t much else on the market covering this protocol. There are of course ISO 10589 and RFC 1195 which covers these protocols, but seeing as this is a short book I thought it might be able to shed some light on an otherwise complex protocol.

In reviewing this book I’ve come up disappointed in general. There are certainly a few golden nuggets and I give the book a couple of stars just for attempting to bridge the gap between the purely theoretical and the purely vendor specific. However, the book comes up short on most other points. Often times I found myself wanting to scrap this book in favor of some of the other selections on the market, but since I have respect for these authors I read the whole book hoping that they might be able to redeem themselves by the time I finished.

Obviously the authors have a great deal of knowledge about the subject, and I don’t fault them entirely. The quality of the editing is poor with many grammatical and syntactical errors littered throughout the text. There are abundant instances throughout the book where the diagrams used do not match the text describing them. I was rather disappointed because I usually find that Addison-Wesley publishes some of the best texts on the market.

All in all, I thought this book could have been a lot better than it was. After all, these authors have several other titles under their belt, most notably “Advanced IP Network Design”. But in this case, I would say that you are better off looking for other similar titles available on the market, such as Jeff Doyle’s “Routing TCP/IP Volume 1” or “The Complete IS-IS Routing Protocol” by Hannes Gredler and Walter Goralski.

The Case for Juniper Press

When was the last time you went into a bookstore and found a book on the bookshelf covering Juniper technologies?  I’ve managed to rarely, if ever, find more than one or two titles on JUNOS or any sort of Juniper related technology.  On the other hand, you’d be hard pressed to miss the bevy of Cisco related titles covering a vast array of technologies and platforms.  When I teach Juniper classes, or I’m on a consulting gig pitching Juniper technologies, one of the things I hear most often is that there aren’t enough resources available to people who want to learn more about JUNOS.  Often the answer is “Well, there’s the Fast Track Program”, or “Well, you can download the free books by Joe Soricelli or Harry Reynolds” (which by the way, it’s high time we get those books back in print – they are excellent books, well written, and in my opinion, second to none when preparing for the Service Provider track).  But often this isn’t enough for the folks who want to learn more.  While Juniper’s Fast Track Program is an extremely valuable resource, it’s coverage is limited to only a few select technologies.  Furthermore, beyond a handful of books on Amazon, there aren’t many additional resources outside of reading Juniper’s technical documentation or various white papers for those students who truly wish to expand their knowledge base.  Sure, the JNCIA-M/T, JNCIS-M/T, JNCIP-M/T, and JNCIE-M/T study guides are freely available, but more often than not people would prefer to have these in hardcopy format rather than in a PDF and printing a PDF doesn’t provide the reader with quite the same experience.  I don’t care what anyone thinks, electronic formats aren’t going to be replacing printed books anytime soon.  Just ask yourself when was the last time you read an entire book on a computer screen?  NOTE TO AUTHORS: A Kindle version would be nice and this would be a good first step, but then again, how many people do you know that actually own a Kindle?

In 1996, when Cisco Press was formed as a joint publishing partnership with Pearson Education, Cisco realized that providing educational materials to meet the growing demand for networking technologies was going to be a cornerstone to their success.  In 1997, “Internet Routing Architectures” by Sam Halabi rolled off the printing press and was an instant best seller.  The rest was pretty much history.  Cisco understood early on that there was a vacuum in the market for high-quality technical books covering the networking arena, and more specifically Cisco technologies.  They met that demand and incidently watched their market share grow to the behemoth they are today.  Since its inception, Cisco Press has published well over 400 titles.  It’s no surprise that given a wealth of educational resources at their disposal, engineers who understand a given technology are more apt to recommend those technologies to their peers, and more importantly, to the people who often end up buying the technology. One only needs to look at the 20,000+ CCIEs in the world today to understand thats a pretty big propaganda machine to silence.

I’ve worked with both Cisco and Juniper technologies for a long time, and I’m convinced that Juniper’s products are infinitely superior, but if Juniper is serious about being a major competitor, especially in the Enterprise market or other market segments outside of the Service Provider arena, it’s high time they think about creating a publication arm which can compete with the likes of Cisco Press.  It might not be the most profitable business, and in fact, if you’re simply looking at dollars and cents with a microscopic view, it might even be a losing proposition.  But the demand is out there, and if they meet it, I am fairly certain Juniper will see their marketshare increase in a really big way.
