As research in Quantum Key Distribution (QKD) technology grows larger and more complex, the need for highly accurate and scalable simulation technologies becomes important to assess the practical feasibility and foresee difficulties in the practical implementation of theoretical achievements. Due to the specificity of QKD link which requires optical and Internet connection between the network nodes, it is very costly to deploy a complete testbed containing multiple network hosts and links to validate and verify a certain network algorithm or protocol. The network simulators in these circumstances save a lot of money and time in accomplishing such task. A simulation environment offers the creation of complex network topologies, a high degree of control and repeatable experiments, which in turn allows researchers to conduct exactly the same experiments and confirm their results.

The aim of Quantum Key Distribution Network Simulation Module (QKDNetSim) project was not to develop the entire simulator from scratch but to develop the QKD simulation module in some of the already existing well-proven simulators. QKDNetSim is intended to facilitate additional understanding of QKD technology with respect to the existing network solutions. It seeks to serve as the natural playground for taking the further steps into this research direction (even towards practical exploitation in subsequent projects or product design).

Here, we provide the QKDNetSim source code which was developed in the network simulator of version 3 (NS-3). The module supports simulation of QKD network in overlay mode or in a single TCP/IP mode. Therefore, it can be used for simulation of other network technologies regardless of QKD.

1) An Open Source project

ns-3 is a free open source project aiming to build a discrete-event network simulator targeted for simulation research and education.
This is a collaborative project; we hope that the missing pieces of the models we have not yet implemented will be contributed by the community in an open collaboration process.

Contributing to the ns-3 project is still a very informal process because that process depends heavily on the background of the people involved, the amount of time they can invest and the type of model they want to work on.

Despite this lack of a formal process, there are a number of steps which naturally stem from the open-source roots of the project. These steps are described in doc/contributing.txt

2) Building ns-3

On the beginning, we need to install prerequisites as root: sudo apt-get install gcc g++ python python-dev mercurial bzr gdb valgrind gsl-bin libgsl2 flex bison tcpdump sqlite sqlite3 libsqlite3-dev libxml2 libxml2-dev libgtk2.0-0 libgtk2.0-dev uncrustify doxygen graphviz imagemagick texlive texlive-latex-extra texlive-generic-extra texlive-generic-recommended texinfo dia texlive texlive-latex-extra texlive-extra-utils texlive-generic-recommended texi2html python-pygraphviz python-kiwi python-pygoocanvas libgoocanvas-dev python-pygccxml git libcrypto++-dev libcrypto++-doc libcrypto++-utils libboost-dev libboost-all-dev

The code for the framework and the default models provided by ns-3 is built as a set of libraries. User simulations are expected to be written as simple programs that make use of these ns-3 libraries.

To build the set of default libraries and the example programs included in this package, you need to use the tool 'waf'. Detailed information on how use waf is included in the file doc/build.txt

However, the real quick and dirty way to get started is to type the command

./waf configure; ./waf

the the directory which contains this README file. The files built will be copied in the build/debug or build/optimized.

The current codebase is expected to build and run on the set of platforms listed in the RELEASE_NOTES file.

Other platforms may or may not work: we welcome patches to improve the portability of the code to these other platforms.

3) Running ns-3

On recent Linux systems, once you have built ns-3, it should be easy to run the sample programs with the following command:

./waf --run scratch/secoqc_3_p2p_qkd_system

That program should generate a simple-global-routing.tr text trace file and a set of simple-global-routing-xx-xx.pcap binary pcap trace files, which can be read by tcpdump -tt -r filename.pcap

4) Getting access to the ns-3 documentation

Once you have verified that your build of ns-3 works by running the simple-point-to-point example as outlined in 4) above, it is quite likely that you will want to get started on reading some ns-3 documentation.

All of that documentation should always be available from the ns-3 website: http:://www.nsnam.org/ but we include some of it in this release for ease of use.
