Course Overview:

Diameter Protocol Training – Hands-on

With the emergence of new technologies and services like mobile broadband, the need for Authentication, Authorization, and Accounting (AAA) functionality has never been greater. Diameter serves as a base protocol that allows peers to exchange a great variety of messages and can be extended in order to provide AAA services to new access technologies. It is the primary signaling protocol for AAA and mobility management in IMS; it finds extensive application for policy and charging in 4G Long Term Evolution (LTE); and is also an integral part of the NGN network.

The Diameter base protocol is intended to provide an AAA framework for applications such as network access or IP mobility. It is also intended to work in both local and roaming situations. This Diameter Protocol Training course covers the architecture, message format, transport, error reporting, message flows, accounting and security services to be used by Diameter applications.

Customize It:

• If you are familiar with some aspects of this Diameter Protocol Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
