Bandwidth Measurement in NS2 using pathChirp Tool

•  You should already have the ns-2 simulator installed. You can obtain ns-2 code here. In the following NS-2-DIR refers to your ns-2.* directory (example: ns-2.27)
  
• Save current files: Before untarring the code below, save a few ns files that will be overwritten so that you can revert to the original easily. 1) cd NS-2-DIR
  2) tar -cvf original.tar Makefile.in FILES tcl/lib/ns-default.tcl tcl/lib/ns-packet.tcl common/packet.h
  
  In case you need to revert to the original code:
  
  1) cd NS-2-DIR
  2) tar -xvf original.tar
  3) make clean
  4) ./configure
  5) make depend
  6) make
  
  
• Download Code: pathchirp_ns_2.27.tar (for ns_2.27), pathchirp_ns_2.26.tar (for ns_2.26)
  
  To add the pathChirp code to ns-2, copy the pathChirp_ns_2.27.tar (or pathChirp_ns_2.26.tar) file to NS-2-DIR and run the following commands.
  
  1) cd NS-2-DIR
  2) tar -xvf pathchirp_ns_2.*tar
  
  If you have not already saved your current files, go to the "Save current files" instructions above. Otherwise follow the instructions in the README_PATHCHIRP file OR proceed as follows.
  
  3) tar -xvf pathchirp_code.tar
  4) make clean
  5) ./configure
  6) make depend
  7) make
  To run an experiment using pathChirp read the README_PATHCHIRP file.
