Hi, I want to run MFTP on NS. I could find a mftp_snd.tcl and a mftp_rcv.tcl. But, I can't understand them completely. I want to deepen the understanding of MFTP more with what is done referring to an sample program like other agents. If there is a person who has the sample program which used MFTP, I want myself to teach it. thanks.
