Q&A with Charles E. Spurgeon, co-author of "Ethernet: The Definitive Guide," 3rd Edition"Q. Why is your book important right now? A. Ethernet is changing, with improvements to existing standards and with the development of new standards for higher speeds, Energy Efficient Ethernet, increasing power over Ethernet, and more. Ethernet, The Definitive Guide 2nd edition has been entirely updated with the changes to existing standards and includes new material covering the very latest in Ethernet technology. Q. What do you hope your readers walk away with? A. This thoroughly revised, comprehensive guide covers a wide range of Ethernet technologies, making it possible for the reader to quickly find what they need. The emphasis is on providing the information that the reader needs to build and manage Ethernet networks ranging in size from a small office system to a large enterprise network for a multi-building campus. The book is designed to provide tutorials on a wide range of topics, including fiber optic and twisted-pair cabling systems and network troubleshooting. Q. What s the most exciting or important thing happening in your space? A. Ethernet's ability to continue innovating is remarkable, as seen with the latest work on the 400 Gigabit per second variety of Ethernet. Ethernet is one of the few computer technologies that has managed to continue growing and evolving over several decades. Ethernet's long history was commemorated by the 40th "birthday" of Ethernet in May, 2013, celebrating the publication of the original Ethernet design memo in 1973. Q. Can you tell us a little more? A. Did you know that Ethernet interfaces are now "green?" The Energy Efficient Ethernet (EEE) standard, approved in late 2010, is now incorporated into most twisted-pair Ethernet interfaces. This allows the interface to automatically configure EEE to save small amounts of power when no data is being sent. And that, in turn, can save much larger amounts of power when the savings

HASH(0x9fd453c0) von 5 Sternen After 14 years, a much-needed update of the first edition 5. April 2014
Von R. D Johnson - Veröffentlicht auf Amazon.com
Format: Taschenbuch Verifizierter Kauf
First, a comment about the update, then the comments about the book itself:

This follows a trend I've noticed in updated editions recently, in that it doesn't actually bill itself as one other than where it says '2nd Edition' on the front cover. There is no 'Preface to the 2nd Edition' or list of changes. If you had never seen the 1st Edition you would have no clue this book was an updated edition. Same octopus on the front cover of the class Cephalopoda, approximately the same number of pages, and a lot of the same content. However, the authors wife Joann Zimmerman is now listed as a co-author, and in the first edition he lived with her and their cat Sophie. He still lives with his wife and cat, but the cat's name is now Mona. (Rest in peace Sophie.)

The purpose, I suppose, is the same as Stroustrup noted in his latest Edition of the 'C++ Programming Language', when rather than highlight the old and the new, he desired instead a snapshot of the current state of the language. This book is similar with respect to Ethernet. It covers the same territory as the 1st edition, so many of the reviews of that book are still pertinent. Many of the sections are almost identical. However, entire chapters and sections of the old book, such as 'Model Configuration Guidelines for 10Mbps' and the entire Appendix B on crimping, wiring and installing thick and thin coaxial media are entirely missing, replaced with a small chapter on 10Mbps Ethernet. Given that coaxial Ethernet is totally obsolete, this is not surprising. The 1st edition had pictures of PCI Ethernet cards, also now gone in the 2nd edition. A small section on Twisted-pair Ethernet and Telephone Signals is still present, but almost entirely rewritten. The fiber optic section has been updated and expanded, dropping old connectors no longer seen and adding new ones. The 1st edition covered up to 1000Base; this 2nd edition now goes up to 100GBase in some detail. There's a tiny chapter on 400G, but it's not much more than a description of the workings of the study group as of 2013. In summary, some now-obsolete parts of the old book are gone or much reduced, a good chunk of the book (eg the 1000Base stuff) is almost identical but with updated editing and terminology, and there's quite a bit of new content covering the changes to Ethernet since the 1st edition's publication in 2000. It's all been mixed, merged, and moved around however, so like with the Stroustrup book it's best if you look at it afresh. On the other hand, if you're still crimping coax connectors you'd be better off picking up the 1st edition (or finding a new job at a modern facility).

If you understood and appreciated the 1st edition you'll enjoy the 2nd just as much, and you won't be wasting your time reading copious details about how to efficiently route half-duplex connections or searching in vain for PoE information (which is discussed in detail in this 2nd edition btw). However, the niche this book covers hasn't changed from the 1st edition. This is a book which describes Ethernet as a layer 1 and layer 2 component of the OSI network stack. Just like the 1st edition, there is little coverage of higher-level protocols such as TCP/IP, NetBIOS, or the like. Those higher-level protocols could be just as easily transmitted by carrier pigeon (OK slight exaggeration perhaps), and Ethernet is just another type of carrier pigeon. If you need TCP/IP information, look elsewhere. If you want to configure a Cisco router, again, look elsewhere. Likewise, this book is not the definitive guide for Ethernet chip designers--there's a few thousand detailed specification pages from the IEEE you can read for that. This book is intended primarily for software, hardware and network engineers and installation technicians who need a broad, detailed understanding of the physical Ethernet infrastructure as it applies to cabling, switching, routing, and configuration at the PHY level. At that it excels.

The one thing this 2nd edition is missing that I wish had been included is some information on IEEE 1588 AVB, now part of IEEE 801.2AS and friends, and the associated IEEE 1722 layer 2 transport protocol. These standards were ratified as of November 2011, but perhaps the authors decided not to cover them as few vendors provide AVB support in their switches at the current time.

HASH(0xa0276f24) von 5 Sternen Fantastic Book on Ethernet Technologies 4. Mai 2014
Von Deshrek - Veröffentlicht auf Amazon.com
Format: Taschenbuch
Disclaimer: This review is for Ethernet: The Definitive Guide, which I obtained my copy free from O'Reilly Reviewer Program.

Ethernet: The Definitive Guide was written by Charles E Spurgeon and Joann Zimmerman, both of whom have been working in this area for decades. In another word, they started working in this area since the dawn of internet era.

The book is some pleasure for reading and when I first started, I actually finished more than one hundred pages without stop. It's not because I used to work in this industry quite a bit, but that the writers are really capable of explaining those technical terms in an easy to understand way and in addition, lots of anecdotes concerning the history of ethernet and companies involving in developing it make the book easy to follow. Your mileage may vary but IMHO, this is one of those technical books that are interesting to read, or even just for some casual reading.

Similar to other definitive guides from O'Reilly, this book intends to be a thorough reference for ethernet technology ranging from archaic BNC to 40G, 100G ethernet and including relatively newer areas such as PoE, FCoE etc. One might wonder whether it make sense to include something like BNC, 10BASE-T that most of us even working on ethernet may never see them. However, given the attribute of complete reference of it, it would be useful to include historically important technologies and you probably would not find such detailed information as in this book elsewhere online, which is sad truth with evolving technologies as a whole.

Given its coverage of media with ubiquitous usage in real world of networking and detailed illustrations of standards (both IOS and IEEE ones), use of switches for network design, troubleshooting tips for problems and performance issues, I found it really useful for network manager/engineer, system engineer or even software testing engineers who need to set up certain topologies of network for their testing. This book, while not a step-by-step setting-up or installation guide provided by vendors for certain products (which you know may be very directly applicable for their products), does go to depth to explain not only how but also why some technologies are designed or used that way.

However, if you are a software developer or tester, you may find this book does not provide enough information in that aspect, which I would not blame it at all given it's never meant to be used that way. You may find All New Switch Book by Rich Seifert and Jim Edwards and Understanding Linux Network Internals by Christian Benvenuti rather helpful in additional to related RFC's etc.
