How to test S6a ,S5/S8 interface?

Question

Can someone suggest me the below requirements:
1. I want to test S6a interface so what are the best possible testing tools available. Open source are highly preferable
2. I want to test S5/S8 interface so what are the best possible testing tools available. Open source are highly preferable

Answer 1

Chinmoy, we (LCN) have S6a/S6d implementation. It is a commercial product. But we offer evaluation license, so you will be able to use it for 1-2 months without buying license, for testing.
Our focus is Diameter and interfaces, and we offer a sample client and server (with C code). But client just sends dummy requests (syntactically complete and correct) and server sends a response. If you are looking for serious MME/HSS simulation, we don't have it. Interface is complete, though.

If this is of interest, let me know.

S5/S8: No.
