This repository contains the implementation of Stochastic Adapative Forwarding (SAF) for ndnSIM version 2.1.

The original SAF implementation can be found at: https://github.com/danposch/saf

The code is provided under the GNU General Public License Version 3.

Prerequisites

Custom version of NS-3 and specified version of ndnSIM needs to be installed.

The code should also work with the latest version of ndnSIM, but it is not guaranteed.

# Checkout latest version of ndnSIM
mdkir persistent-interests
cd persistent-interests
git clone https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3
git clone https://github.com/named-data-ndnSIM/pybindgen.git pybindgen
git clone --recursive https://github.com/named-data-ndnSIM/ndnSIM.git ns-3/src/ndnSIM

# Set correct version for ndnSIM and compile it
cd ns-3
git checkout 2c66f4c
cd src/ndnSIM/
git checkout a9d889b
cd NFD/
git checkout 85d60eb
cd ../ndn-cxx/
git checkout 787be41
cd ../../../
./waf configure -d optimized
./waf
sudo ./waf install

Compiling

To configure in optimized mode without logging (default):

./waf configure

To configure in optimized mode with scenario logging enabled (logging in NS-3 and ndnSIM modules will still be disabled, but you can see output from NS_LOG* calls from your scenarios and extensions):

./waf configure --logging

To configure in debug mode with all logging enabled

./waf configure --debug

If you have installed NS-3 in a non-standard location, you may need to set up PKG_CONFIG_PATH variable.

Running

In addition to SAF this repository contains a sample scenario to test the functionality of SAF.

./waf --run=simple-saf --vis

Debug Information about SAF can be printed with the option NS_LOG=nfd.SAF:

NS_LOG=nfd.SAF ./waf --run=simple-saf --vis
