model: Extending ndn::fib::Entry to provide access to RTT estimate
For more information, including downloading and compilation instruction, please refer to documentation in doc/ or on http://ndnsim.net
ndnSIM has been successfully compiled and used under Ubuntu Linux 12.04 (boost libraries 1.48, with default version 1.46 compilation will probably fail), 12.10 (default version of boost 1.49), 13.04 (default version of boost 1.49), Fedora 18, Mac OS 10.7 and 10.8 (gcc-4.2 apple/llvm, macports gcc 4.7, boost 1.49-1.54).
ndnSIM requires the customized version of NS-3 simulator (a number of patches required to make ndnSIM work with the latest development branch of NS-3).
Boost libraries should be installed on the system:
For Ubuntu
12.04
sudo aptitude install libboost1.48-all-dev
12.10, 13.04, and newer versions
sudo aptitude install libboost-all-dev
For Fedora (for Fedora 18 and later only):
sudo yum install boost-devel
For MacOS (macports):
sudo port instal boost
!!! ndnSIM requires boost version at least 1.48. Many linux distribution (Fedora 16, 17 at the time of this writing) ship an old version of boost, making it impossible to compile ndnSIM out-of-the-box. Please install the latest version, following these simple instructions (http://ndnsim.net/faq.html#installing-boost-libraries).
For Ubuntu 12.04 Ubuntu 12.04 ships with two versions of boost libraries and it is known that if both are installed, then compilation of ndnSIM will most likely fail. Please install libboost1.48-dev-all package and uninstall libboost-dev-all. If you want to install the latest version of boost libraries, then uninstall both libboost1.48-dev-all and libboost-dev-all, so the libraries do not interfere with each other.
If you do not have root permissions to install boost, you can install it in your home folder. However, you need to be make sure that libboost_iostreams library is successfully compiled and is installed. Please refer to the following example http://ndnsim.net/faq.html#installing-boost-libraries for the hints how to successfully compile and install boost libraries on Ubuntu Linux.
For Ubuntu (tested on Ubuntu 12.04, 12.10, 13.04, should work on later versions as well):
sudo apt-get install python-dev python-pygraphviz python-kiwi sudo apt-get install python-pygoocanvas python-gnome2 sudo apt-get install python-gnomedesktop python-rsvg ipython
For Fedora (tested on Fedora 16):
sudo yum install pygoocanvas python-kiwi graphviz-python # easy_install method, since pygraphviz is not (yet?) packaged into Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=740687) sudo yum install graphviz-devel sudo yum install python-pip sudo easy_install pygraphviz
For MacOS (macports):
sudo port install py27-pygraphviz py27-goocanvas
Download a custom branch of NS-3 that contains all necessary patches, python binding generation library (optional), and clone actual ndnSIM code and place it in src/ folder:
mkdir ndnSIM cd ndnSIM git clone git://github.com/cawka/ns-3-dev-ndnSIM.git ns-3 git clone git://github.com/cawka/pybindgen.git pybindgen git clone git://github.com/NDN-Routing/ndnSIM.git ns-3/src/ndnSIM
There are quite a few modification to the base NS-3 code that are necessary to run ndnSIM, and the code is periodically synchronized with the official developer branch. Eventually, all the changes will be merged to the official branch, but for the time being, it is necessary to use the customized branch.
If you have problems connecting to github, you can try to clone from google servers:
mkdir ndnSIM cd ndnSIM git clone https://code.google.com/p/ndnsim.ns3-base/ ns-3 git clone https://code.google.com/p/ndnsim.pybindgen/ pybindgen git clone https://code.google.com/p/ndnsim/ ns-3/src/ndnSIM
ndnSIM uses standard NS-3 compilation procedure. Normally the following commands should be sufficient to configure and build ndnSIM with python bindings enabled:
cd <ns-3-folder> ./waf configure --enable-examples ./waf
On MacOS (with macports), you may need to modify the configure command to use macports version of python:
cd <ns-3-folder> ./waf configure --with-python=/opt/local/bin/python2.7 --enable-examples ./waf
Python bindings is an optional and not very stable feature of NS-3 simulator. It is possible to disable python bindings compilation either to speed up compilation or to avoid certain compilation errors (e.g., "Could not find a task generator for the name 'ns3-visualizer'"):
cd <ns-3-folder> ./waf configure --disable-python --enable-examples ./waf
For more configuration options, please refer to ./waf --help.
To run :doc:sample ndnSIM simulations <examples>:
./waf --run=ndn-simple
or:
./waf --run=ndn-grid
If you have compiled with python bindings, then you can try to run these simulations with visualizer:
./waf --run=ndn-simple --vis
or:
./waf --run=ndn-grid --vis
Do not forget to configure and compile NS-3 in optimized mode (./waf configure -d optimized) in order to run actual simulations.
While it is possible to write simulations directly inside NS-3 (in scratch/ folder) or ndnSIM (in examples/), the recommended way is to write your simulation scenarios, as well as any custom extensions, separately from the NS-3 or ndnSIM core.
For example, you can use the following template to write your extensions, simulation scenarios, and metric processing scripts: (http://github.com/cawka/ndnSIM-scenario-template):
mkdir ndnSIM cd ndnSIM git clone git://github.com/cawka/ns-3-dev-ndnSIM.git ns-3 git clone git://github.com/cawka/pybindgen.git pybindgen git clone git://github.com/NDN-Routing/ndnSIM.git ns-3/src/ndnSIM # Build and install NS-3 and ndnSIM cd ns-3 ./waf configure -d optimized ./waf sudo ./waf install cd .. git clone git://github.com/cawka/ndnSIM-scenario-template.git scenario cd scenario export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH ./waf configure ./waf --run <scenario>
