DIAMETER stack for AAA functions in IMS networks
Netbricks DIAMETER stack called DIAMETER-BRICKS™ is a source code implementation of the AAA protocol suite as
laid down by the IETF AAA Working Group.
DIAMETER is a signaling protocol that has been specified by IETF to perform AAA (Authentication,
Authorization and Accounting) functions in IMS (IP multi media system) next generation networks. DIAMETER has also been adopted by 3GPP and 3GPP2 standardization bodies for AAA in IMS
mobile systems and networks and is designed to perform these functions in both local and roaming
(ROAMOPS model) situations.
DIAMETER has been designed to ensure as much as possible backward compatibility with RADIUS (Remote Authentication Dial In User Service) protocol widely deployed in current intranet and internet
configurations. DIAMETER introduces many enhancements in order to address several RADIUS
shortcomings and deficiencies : no end to end security, limited size of length and identifier fields,
limited failure detection mechanism…
The software architecture for the DIAMETER stack is made up of two parts:
 |
The Netbricks API which contains all the Diameter Interfaces.
The Diameter stack which contains the protocol layers and the system management layer.
Diameter-Bricks and the several User applications are running into independent processes.
Communication between Netbricks Stack and User applications is available through different mode of communication channels.
