Diameter

Preface

Why Did We Write This Book?

“To make money,” you will say. That was, however, not our motivation.

We all have been working on Diameter for several years in different roles and therefore we are regularly involved in discussions about Diameter specification questions, or questions about system design and implementation. Often, we go through the same discussions again and again – just with different people.

There was, however, no book to recommend to our co‐workers and friends. While we were attending the IETF #86 meeting in Orlando, we sat together outside the conference venue and talked about how to address the common questions we receive. The idea to write a book was born. We reached out to Sébastien, who maintains the freeDiameter implementation, and asked him if he would be willing to help us by creating freeDiameter examples since we prefer hands‐on examples in our technical books.

Since two of us had worked with Wiley before on other book projects, we reached out to Wiley again to socialize our idea. To keep it short, you are now holding a Diameter book in your hands.

We hope you enjoy our approach in making you a Diameter expert. We have set up a dedicated website with additional material for this book. If you have questions or feedback, please send us an email at ([e-mail]) or visit our webpage at https://diameter‐book.info.
