An open testbed for diameter networks

The recent deployment of LTE and IMS networks was not always beneficial. It also introduced new challenges for mobile network operators, researchers and industry experts. To be more precise, the dominant usage of the Diameter protocol in mobile signaling networks is getting increasing consideration in terms of interoperability, scalability and security. This paper briefly presents significant efforts to mitigate such challenges. Moreover, a new testbed for testing, evaluating the usage of Diameter in LTE-IMS mobile networks is introduced. In the testbed, the main components are either implemented by ourselves or collected from existing open source software solutions. By using a generic approach for Diameter provisioning, the testbed is open to new components and new Diameter applications.
