Hi,

my suggestion is to use DCE or ns-3 in emulation mode. You can also add a library to ns-3, if you have an IKE library.

Developing the whole IKE protocol in ns-3 is possible, but kinda hard.

I don't know how to start actually, I have many open source for IKE but I don't know how to develop it using ns3. How can I use ns3 in emulation mode?
