MFTP port to ns-2

[Christoph Haenle <chris@cs.vu.nl>]

Hello ns-2 developer team,

you said that you are glad about ports of existing multicast protocols to ns-2.
I've ported the core of MFTP's file transfer phase ("Multicast File Transfer 
Protocol"). Also implemented is the erasure correction enhancement that 
I have been talking of at the IRTF-meeting in Cannes. Don't think my sources 
are stable enough for a permanent integration it into ns-2, but they could 
well yield an optional an extension package.

For the extension package, I'd need the following from your ns-developers:

(1) a payload-type "PT_MFTP" in file "trace.h", which could be permanently 
assigned (i.e. even be defined if the extension package is not used).

(2) an entry "{ MFTP off_mftp_}" in the foreach-loop of "Simulator instproc 
create_packetformat" in file ns-packet.tcl, which again could be installed 
permanently assigned.

(3) 4 instructions:
      source ../mcast/mftp.tcl
      source ../mcast/mftp_snd.tcl
      source ../mcast/mftp_rcv.tcl
      source ../mcast/mftp_rcv_stat.tcl
    in file ns-lib.tcl (which must only be added manually if the
    MFTP-package is used).

(4) 4 entries in Makefile.in (OBJ_CC:)
      mftp.o \
      mftp_snd.o \
      mftp_rcv.o \
      codeword.o
    Again, these four lines should not be present unless MFTP is used.


There is further info (incl. demo script and tracefile) available under

Do you have any suggestions on how to seamlessly integrate the extension package on demand into ns-2?

     -Chris.
