[ns] how to specify the byte rate of tcp sender

[Neundorf Alexander <Alexander.Neundorf.extern@icn.siemens.de>]

Hi,

I wanted to do something like a cbr tcp source, I took the Telnet class as example. I did the following:

mainly I changed this function:

void MyTestApp::timeout()
{
   if (running_)
   {
      int sendNow=bitrate_/80;
      agent_->sendmsg(sendNow);
      timer_.resched(0.1);
};

Now my tcp source generates packets 10 times per second, but their size is *always* 1000 bytes. If I set bitrate_=64000, it should send 800 bytes at once. So my received bitrate is 80.000 bit per second (10 x 1000 bytes per second, x 8 bit per byte) instead of the expected 64000.
I already found that TCPAgent::output() uses hdr_cmn->size, which is 1000. What am I doing wrong ?

Bye
Alex
