This report describes how to use the provided script for NFD performance benchmark
on ONL (https://onl.wustl.edu/).
  
Assumptions
===========

  This report assumes that users have an ONL account. If you don't have an account
  yet, please refer to the ONL official website to apply.


Experiment Steps
================

  1. Login on the onlusr machine:
     ssh -L 7070:onlsrv:7070 <your_account>@onl.arl.wustl.edu
  
  2. Run RLI
     Open the topology file, and make reservation; if it is not successful,
  change the reservation time, and try again
  
     When your reservation is ready, commit.
     
  3. Experiment Environment setup
     ONL does not allow us to install programs, this section describes the process
     to compile NFD code on your experiment nodes.

     (1) clone script on onlusr

         git clone https://github.com/WU-ARL/NFD_Performance_Testing_on_ONL.git

     (2) Log on to one of the pc2core experiment nodes

         In RLI, you can see the nodes name. Just choose one, and ssh to it.
     
     (3) Compile and install ndn-cxx in your home directory. And then the NFD code.

         The scripts make it pretty easy to do so. The README in scripts explained it clearly.
         Here we just point out the main steps:

         A. in NFD_current_git fold, run “./git_initial.sh”.
            This script would download the latest code repository to your current directory.

         B. run “./build_all.sh”
            build_all.sh compiles and installs the ndn-cxx and NFD in the usr folder of your
         current directory.


NFD Throughput Benchmark
========================

  1. logout the pc2core node. cd to the Variable_Length_Names folder.

  2. run mkAll.sh to configure the experiment

     Usage: ./mkAll.sh [options] <count> <proto> <interval> <num name components> <component length>
     Options:
       [--local]     - use start scripts to run local (../NFD_current_git_optimized/usr/local/bin/) versions of nfd and nrd
       [--installed] - use start scripts to run the installed (based on PATH) versions of nfd and nrd

      e.g. ./mkAll.sh --local  64 udp4 8 5 5

  3. start the experiment: ./runAll.sh

  4. stop the experiment: ./killAll.sh

     John also provided another script to simplify the experiment: “seriesTest.sh”. You can modify it
  to make your work easier by changing the parameters.



NFD Forwarding Latency
======================

  1. ssh to the NFD router, use tcpdump to capture traffic:
    sudo tcpdump -i data0 'port 6363' -c 1000 -vv -w /tmp/mkall-16-udp4-10-1-5.port6363.pcap

  2. run the script
