[Ns-developers] TCP and UDP layer refactoring

[Sébastien Vincent]

Hi,

I am back after having done some STUN / TURN stuff. Sorry to not have 
given some news the past two weeks, I was very busy.

Now I have time to do the prototype of TCP / UDP refactoring in NS-3. I 
will read again all the previous e-mail and begin the implementation 
next tuesday.


Regards
