Presents the principles, design, development and applications of the Diameter protocol suite

The Diameter protocol was born in the Internet Engineering Task Force (IETF) and designed to be a generalpurpose Authentication, Authorization, and Accounting (AAA) protocol applicable to many network environments. This book is for everyone who wants to understand the Diameter protocol and its applications. This book explains the place Diameter holds in global telecommunication networks and teaches system architects and designers how to incorporate Diameter into their network environments.

Diameter: New Generation AAA Protocol Design, Practice and Applications begins by describing the foundation of Diameter stepbystep, starting with building blocks of the protocol, and progressing from a simple twoparty exchange to a multiparty exchange involving complex routing. It discusses the motivation for using Diameter, talks about its predecessor, RADIUS, and introduces the open source Diameter implementation, freeDiameter. The book expands beyond protocol basics to cover endtoend communication, security functionality, and realworld applications, extending to the backend infrastructure of mobile telecommunications. In addition, an advanced chapter teaches readers how to develop Diameter extensions for their own AAA applications.

Written by an experienced author team who are members of the group that standardized Diameter in the IETF and are at the forefront of this cuttingedge technology

Presents the stilldeveloping topic of Diameter from both introductory and advanced levels

Diameter:

New Generation AAA Protocol Design, Practice and Applications will appeal to system architects and system designers, programmers, standardization experts new to Diameter, students and researchers interested in technology that is deployed by many network operators.
