This is ExpressPass implementation on ns-2.35
Ns should configure and build on Unix systems with GNU autoconfigure.

Quick Start:
  1. Download the ns-allinone-2.35.tar.gz and extract it.
    wget -O ns-allinone-2.35.tar.gz http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download
    tar -xvzf ns-allinone-2.35.tar.gz
  2. Remove the original ns-2.35 directory
    cd ns-allinone-2.35
    rm -rf ns-2.35
  3. Clone this git repository and change the directory name to 'ns-2.35'
    git clone https://github.com/Kwangwook-Kwon/ns2_HPC.git
    mv ns2_HPC ns-2.35
  4. Configure & compile the codes
    ./install
    if it fails, need to install aditional programs
     sudo apt install libx11-dev
     sudo apt-get install xorg-dev
  5. Now you can run sample scripts in ns-2.35 directory
    cd ns-2.35
    ./ns scripts/simple-send-recv.tcl
  6. Output file (trace file and flow completion time) is available in outputs directory.
    vim outputs/fct.out
    vim outputs/trace.out
    vim outputs/mp_ftc.out
    vim outputs/mp_wast.out
