Book Description
Editorial Reviews
From the Inside Flap
Preface A lot of literature about ATM seems to focus on the wonderful things that will happen when the whole world uses it, but few talk much about how to run today's networks over it. Since the recent explosive growth of the collection of IP networks we call the Internet has made it pretty clear that TCP/IP is here to stay, I though it would be a good idea for a book to discuss ATM in the context of IP. One problem in writing a book is deciding what to put in and what to leave out. There's so much data on ATM lying around that if I put it all in, this book's size would rival that of the Encyclopædia Britannica. That would make my publisher unhappy. On the other hand, I could just say "ATM is a networking technology that hooks computers together. It's cool" and be done, but then you'd just read the whole book in the store and not buy it. That would make my publisher unhappy, too. So somewhere in between is a happy medium. The problem is that for every person out there, that happy medium is in a different place. You probably want more nitty-gritty technical information than your boss does, and less than the people who report to you do. So here's what I've tried to do: I'm trying to aim this book at people who are familiar with networking in general, but don't know much about ATM. You want to know how things work in some detail, but not so much detail that bits get in the way of concepts. That's what I've tried to do. If you need to go off and build a LAN Emulation server, or put UNI signalling into a router, you won't get all the information to do it here. What you will get is a pretty good idea of how LAN Emulation or UNI signalling works, and where to go to learn more. I've tried to keep the tone of the book informal, yet accurate, since I like to read that kind of book. On the other hand, I feel a need to apologize for the unavoidable ragôut of acronyms. Any field has it's jargon, and networking has as many special terms and acronyms. One of the hardest initial barriers for myself to learning about ATM was the new set of acronyms I had to learn; since ATM's standards for the most part come out of the telecommunications industry and not from the more familiar data networking community, they tend to use a different set of names for everything. I've put everything I can think of into the glossary. Put a bookmark there as you read the book, it will help. There's a fair amount of detail on protocols, packet formats and the like, which helps to illustrate how devices get information back and forth, and which can help you if you have to dig out a network sniffer and decode the raw cells to find out why the net is down-something I've done more than once! I should point out that since the Internet and ATM is evolving in, well, Internet time, that some of the information in this book may be out of date by the time you get it. I hope the basics of how things work will remain stable, whatever happens to the fine details. I've tried to be clear about what versions of standards I'm referencing, as well as provide pointers for what may be more up-to-date on-line information. On-line data changes rapidly, though, and World Wide Web URLs are not guaranteed to be accurate indefinitely. In particular I've avoided putting in much information about specific equipment and manufacturers. I don't want to make recommendations of what to buy since the market will have changed by the time you read this; but the way ATM works will stay the same. A word about timeliness: this is a field that is rapidly changing. Some of the information in this book takes the form of World-Wide Web URLs, the "Uniform Resource Locators" that allow you to access web pages. Whether they are still valid when you go to type them into your browser is something I cannot control. If you have trouble accessing any of them, try using one of the many search engines to look for the topic; you may find that the keepers of the data just rearranged their files and gave what you're looking for a new name. On the other hand, some of these URLs will just be bogus after a while; I'm sorry about that but I feel it's better to give a lot of pointers, some of which will be useful, than none at all. I'd like to acknowledge the invaluable assistance of Steve Walters, Radia Perlman, John S. Swenson and J. Bryan Lyles without whom this book would have been a lot less accurate and interesting. And of course, nothing in this book should be regarded as the official position of Xerox Corporation, my current employer. In particular any mention of specific products is made only to illustrate a point or provide examples and should in no wise be construed as an endorsement (or otherwise) of any product by Xerox. They may wish to endorse things, or not, but I am not their spokesperson! Here's a sketch of what the rest of the book is up to: Chapter 1: Introduction, including a discussion of standards organizations relevant to ATM and TCP/IP. Chapter 2: TCP/IP. A brief introduction to the TCP/IP protocol suite for folks that are not familiar with it. Chapter 3: SONET and other physical media. How bits get carried at high speed over various links. Chapter 4: ATM. How ATM itself works.Cells, switches, virtual circuits, signalling and so on. Chapter 5: Management. SNMP, ILMI, and ATM routing. Chapter 6: Classical IP over ATM. The IETF's way. Chapter 7: LAN Emulation. The ATM Forum's way. Chapter 8: Multicast, or how can you send packets to more than one place at a time? Chapter 9: Traffic Management. ABR, UBR. QoS. RSVP Flow control. Chapter 10: How to make it fast. Just plugging in an ATM card isn't enough, you've got to tune everything up. Chapter 11: Research Topics. A sampling of what's under active development. The chapter most likely to be out of date when this book is published, let alone five years from now. I'll close with a bibliography, glossary, index and pointers to more information on-where else?-the Internet.

Not worth the money,
By A Customer
This review is from: TCP/IP Over ATM (Prentice Hall Series in Computer Networking and Distributed) (Hardcover)
If you expect to find in depth info about tcp or atm, you'll definately disapointed. This book is only good for people who don't know anything about tcp/ip or atm. (In that case, one would not buy this book). The book starts with overview of tcp/ip and atm(using 2 chapters). Then, it use one short chapter to talk about how ip is over atm. Then it talks about other things like snmp, ip multicast, etc... which I don't really interest in. Don't let the title of the book fool you. You can get much more info regarding ip over atm with any other ATM books.

Good in parts, bad in others,
By A Customer
This review is from: TCP/IP Over ATM (Prentice Hall Series in Computer Networking and Distributed) (Hardcover)
On the one hand, reading this book gives a pretty good overview of TCP/IP over ATM. However, it's pretty short (just barely 200 pages altogether, with almost 40 pages of backmatter)--the price is pretty high considering the length. And, I've got serious problems with the content.What's troublesome are the copy editing lapses. There seem to be a lot of instances where an acronym is used without first defining it--this is why it's so hard to read the source RFCs on ATM, and why a book like this could be so helpful if it were clearer. And not all acronyms are included in the glossary, making it worse. And the fact that there are a fair number of typos that didn't get caught makes me wonder how accurate the rest of the book is. Also, for example, Kercheval refers to NHRP as the "Next Hop Routing Protocol" yet the source (and the bibliography) correctly refer to the Next Hop Resolution Protocol. Although Kercheval states in the introduction that everything will be explained clearly so that even people without an ATM background will get it, that doesn't always seem to be the case. Even so, if you really need to try to figure out the main issues related to running IP over ATM, this is probably as good a book as any now available. This would actually be a great book if it were more closely edited for accuracy, though.

This book provides a very concise review on the subject.,
By A Customer
This review is from: TCP/IP Over ATM (Prentice Hall Series in Computer Networking and Distributed) (Hardcover)
This book does not get into much detail on every topic that it covers. Any book on ATM should have covered more on "TCP/IP over ATM". I didnot get much after I read this book. Therefore, I don't recommend this book.
