 The Diameter protocol serves as a cornerstone in any modern telecommunication backend, providing authentication, authorisation, and accounting (AAA) services in 3G, IMS, 4G, and 5G networks. Several vendors offer commercially licensed Diameter stacks, most of which are written in C++. As a result, many in the Java world have turned to the open-source RestComm JDiameter stack.

 The solutions we developed were functional, but they felt more like a Quarkus application with a JDiameter sidecar. The Diameter stack operated independently, without leveraging the benefits offered by the Quarkus framework.

 Eventually, my frustration with the sidecar approach of integrating JDiameter with Quarkus led me to develop a solution that would allow the two to work more harmoniously. This initiative resulted in the creation of the Quarkus JDiameter extension.

 The Quarkus JDiameter stack has been released and is now part of Quarkiverse Hub. You can find it at link:https://github.com/quarkiverse/quarkus-jdiameter[Quarkiverse Hub]. Documentation for the stack is available at link:https://docs.quarkiverse.io/quarkus-jdiameter/2.0.0/index.html[Quarkus JDiameter Documentation].

 There is still considerable potential for tighter integration of the JDiameter stack into the Quarkus framework. A future project could involve exposing the statistics collected in the stack via the Quarkus MicroProfile Metrics interface.
