Kurzbeschreibung
ASN.1 Complete is a comprehensive tutorial/reference detailing the fundamental features and applications of the 'abstract syntax notion .1' programming language. ASN.1 is a formal language for abstractly describing messages to be exchanged between distributed computer systems. ASN.1 has been used for years in the preparation of international programming standards including application, national, and international standards. While not an 'everyday' language such as C++, C, and Java, ASN.1 is an internationally standardised language used by a wide variety of programmers and engineers to develop and implement communications procedures for hardware.
Synopsis
ASN.1 Complete teaches you everything you need to know about ASN.1-whether you're specifying a new protocol or implementing an existing one in a software or hardware development project. Inside, the author begins with an overview of ASN.1's most commonly encountered features, detailing and illustrating standard techniques for using them. He then goes on to apply the same practice-oriented approach to all of the notation's other features, providing you with an easy-to-navigate, truly comprehensive tutorial. The book also includes thorough documentation of both the Basic and the Packed Encoding Rules-indispensable coverage for anyone doing hand-encoding, and a valuable resource for anyone wanting a deeper understanding of how ASN.1 and ASN.1 tools work. The concluding section takes up the history of ASN.1, in terms of both the evolution of the notation itself and the role it has played in hundreds of protocols and thousands of applications developed since its inception.Features* Covers all the features-common and not so common-available to you when writing a protocol specification using ASN.1.* Teaches you to read, understand, and implement a specification written using ASN.1.*Explains how ASN.1 tools work and how to use them.* Contains hundreds of detailed examples, all verified using OSS's ASN.1 Tools package.* Considers ASN.1 in relation to other protocol specification standards.

Einleitungssatz
A computer protocol can be defined as A well-defined set of messages (bit-patterns or-increasingly today-octet strings), each of which carries a defined meaning (semantics), together with the rules governing when a particular message can be sent. Lesen Sie die erste Seite

I really can't follow the recension above about the quality of the book. The author makes it hard to understand what he means and always tries to be funny. He points out unimportant things like what "...." within a code fragment means and refers to short code examples 20 pages above. He thinks that it is necessary to use (3) bracket pairs in one (relatively small) sentence to make the sense of a sentence (much more) (un-) clear. I gave you an example. Certainly the author knows very much about ASN.1. But the book is hard (!) to read and the structure is not clear. I stopped reading at page 57 and certainly will look somewhere else to teach me ASN.1.

This book does an excellent job of not only explaining how ASN.1 works but why it works that way. It is obvious that the author is an expert in this field. His explanations are clear and he makes good use of diagrams. He also draws on historical evidence and his own experiences.
The author has a literary style that makes what could be a dry and boring subject easy to read, and in some places quite entertaining.

Excellent Selection
10. April 2001
Format:Taschenbuch|Von Amazon bestätigter Kauf
This book is excellent ASN.1 reference material as well as a strong instructional work dealing with ASN.1. 'ASN.1 Complete' was apparently aimed for a multilevel audience: People who have no prior experience with ASN.1, those who are learning ASN.1, and those who merely require satisfactory reference material on ASN.1. For all intents and purposes the author successfully geared the discussions toward any person who deals with ASN.1 on any basis, as they would evolve in their usage of ASN.1. Larmouth does not discuss the material in a monotonous manner as do so many other authors, however he is able to teach with 'programmer's sarcasm and humor', without deviating from the purpose he is teaching. A rather difficult task at times. The only major weakness of 'ASN.1 Complete' is, inevitably, the inability to provide the 'absolute beginner' with the information required to apprehend the information upon it's introduction. The non-familiar reader would be best off reading Section 1 straight through and then going back to re-read all of the sections from the beginning.
Section 1: Section 1 introduces ASN.1, describes it's intents and history. Larmouth gives the reader an overview of the ways ASN.1 can be used and how it is implemented (the theory behind implementation). Most of the basic features are introduced, not discussed in great detail.
Section 2: The basic areas of ASN.1 are discussed thoroughly, and many intermediate topics are introduced and explained. Larmouth usually gives examples supporting the current discussion. Toward the end of the section Larmouth dedicates chapters to the more advanced areas, giving a better understanding to the reader.
Section 3: Mostly for implementors and programmers, Section 3 ventures deep into the sets of encoding rules. Larmouth focuses on the 2 most common sets of encoding rules BER and PER. It would seem that the author favors PER, however the discussions are very relevant and explain many things that an implementor must know.
For the person that is beginning to learn ANS.1 this is an excellent selection; it will teach ASN.1 to the reader and give a much needed overall understanding to ASN.1 very quickly. It is obvious that the author has done his homework. Anyone at any stage of ASN.1 usage would find this as an excellent addition to a reference library; finding specific topics with ease is not a problem. Tip: sometimes the notes on the sides of the page contain humor, but most of the time, the information is very useful. Keep in mind also that this book was not necessarily written to be read straight through, ironically it is only necessary to read the sections and chapters that apply to the information that is needed.

Far more interesting than the protocol
30. November 2004
Format:Taschenbuch
I read this book cover to cover back when I had to deal directly with parsing ASN.1. The book is an interesting read, excellently and expertly written. Moreover, I felt like an expert when I finished reading it; I took my new-found knowledge and applied it to my work at hand. Of course, there are portions of the book that are more theoretical than practical, and I didn't have the tools available to build ASN.1 parsers from rules. However, ASN.1 is important despite the dearth of information on it. This book doesn't merely fill the void - it makes a dry topic interesting.
