Getting Started¶
In INET simulations, configurator modules are commonly used for assigning IP addresses to network nodes and for setting up their routing tables. There are various configurators modules in INET; this tutorial covers the most generic and most featureful one, Ipv4NetworkConfigurator. Ipv4NetworkConfigurator supports automatic and manual network configuration, and their combinations. By default, the configuration is fully automatic. The user can also specify parts (or all) of the configuration manually, and the rest will be configured automatically by the configurator. The configurator’s various features can be turned on and off with parameters. The details of the configuration, such as IP addresses and routes, can be specified in an XML file.
This is an advanced tutorial, and it assumes that you are familiar with creating and running simulations in OMNeT++ and INET. If you aren’t, you can check out the TicToc Tutorial to get started with using OMNeT++.
Try It Yourself¶
If you already have INET and OMNeT++ installed, start the IDE by typing
omnetpp, import the INET project into the IDE, then navigate to the
inet/tutorials/configurator folder in the Project Explorer. There, you can view
and edit the tutorial files, run simulations, and analyze results.
Otherwise, there is an easy way to install INET and OMNeT++ using opp_env, and run the simulation interactively.
Ensure that opp_env is installed on your system, then execute:
$ opp_env run inet-4.0 --init -w inet-workspace --install --chdir \
-c 'cd inet-4.0.*/tutorials/configurator && inet'
This command creates an inet-workspace directory, installs the appropriate
versions of INET and OMNeT++ within it, and launches the inet command in the
showcase directory for interactive simulation.
Alternatively, for a more hands-on experience, you can first set up the workspace and then open an interactive shell:
$ opp_env install --init -w inet-workspace inet-4.0
$ cd inet-workspace
$ opp_env shell
Inside the shell, start the IDE by typing omnetpp, import the INET project,
then start exploring.
