[nipa patani]

hello bs-3 users,

I want to set ping traffic in a attached file..
please provide me the solution.

I am getting error V4PingHelper not declared and also ping not declared.
Please suggest me as i m modifying .cc file for  application of mixed traffic like TCP,UDP and ping.

Thanks in advance..

Hi,

as the code suggests, this is a lab assignment.

It would be wrong to tell you the solution, because the whole point is to let you find it.

However, I can tell you that it's a very simple programming mistake.
