Open Diameter conformance testing

The diameter base protocol, originally developed by the Internet Engineering Task Force (IETF), provides the authentication, authorization and accounting (AAA) functionality needed for network access and mobility in IP-based networks. Diameter has also been adopted by the Third Generation Partnership Project (3GPP) and other standards bodies as an AAA framework in the IP multimedia subsystem (IMS). With the growing interest in diameter, there is an ongoing effort to develop an open source diameter implementation under the open diameter project (http://www.opendiameter.org/). This paper presents the results of conformance testing of open diameter release 1.0.7-i. We describe the test cases, our laboratory environment and test results, with the goal to provide a neutral evaluation of this implementation to the open diameter community, as well as to potential future diameter application testers and developers.
