Well ... there are open source examples, but you have to remember:
- DIAMETER is a standard shell - the actual AVP format, their structure, their serialization, etc. is a fully defined provider.
- DIA is agnostic about whether to use encryption and what form should be used.
You can get DIAMETER "simulations", but without knowing the AVP, their format, encryption rules, etc., you are likely to stay a little longer than the TCP stream in XML format.
