Dear Sally, I read that ns-2.30 is just out, so I suspect that your new tfrc is in there. However, if I understand you correctly, your new modifications on TFRC is related to tfrc.cc file only. Is there any way of finding your modified tfrc.cc file anywhere on the nsnam web page? Well, that would make it much easier for me to "patch" my v2.28 ns. A complete upgrade to new version in ns takes more time.
