I read that ns-2.30 is just out, so I suspect that your new tfrc is inthere. However, if I understand you correctly, your new modifications onTFRC is related to tfrc.cc file only. Is there any way of finding your modified tfrc.cc file anywhere on the nsnam web page?
You could look at: http://nsnam.cvs.sourceforge.net/nsnam/ns-2/tcp/tfrc.cc?view=log - Sally http://www.icir.org/floyd/
