TGen is a C application that generates traffic flows between other Tgen instances. The characteristics of the traffic (e.g., size, timing, number of parallel flows, etc.) can be configured by the user.
TGen can generate complex traffic patterns. Users write relatively simple
python scripts to generate
graphml files that are then used as TGen
configuration files that instruct TGen how to generate traffic.
Dependencies in Fedora/RedHat:
sudo yum install cmake glib2 glib2-devel igraph igraph-devel
Dependencies in Ubuntu/Debian:
sudo apt-get install cmake libglib2.0 libglib2.0-dev libigraph0v5 libigraph0-dev
Build with a custom install prefix:
mkdir build && cd build cmake .. -DCMAKE_INSTALL_PREFIX=/home/$USER/.local make
Optionally install to the prefix:
Run TGen with a single argument (the path to a config file). For example, first run a server:
tgen resource/tgen.server.graphml.xml > tgen.server.log
and then run a client that connects to the server:
tgen resource/tgen.webclient.graphml.xml > tgen.client.log
See the resource/ directory for example config files.
See doc/Tools-Setup.md for setup instructions for
the TGenTools toolkit that can be used to parse and plot
tgen log output.
See doc/TGen-Modeling.md for examples of how to generate TGen config files with embedded traffic models.
See doc/TGen-Config.md for the format of the configuration file and the possible options that can be used when generating traffic models.
