Hello Tom,
thank you for your reply.
I assumed, that mentioned warnings are root cause of my problem, because
from my point of view, there is nothing that could cause problem.
But as you said, you do not have this problem, so cause will be probably
elsewhere - but I have no idea where it could be.
I have normally installed ns-2.35 (./install), set enviroment variables as
requested and validate installation (./validate) - everything successful.
Everything works fine for me except DCCP agents, which returns error
message (please see attachement). I tried to run simulations with another
agents like TCP Newreno, Vegas, Linux and it runs well.
Do you have any idea or advice on possible causes of this issue ?
Thank you in advance.
