Channels YAML file

The “channels.yaml” file is optional. It is used to specify what custom channels classes should be dynamically imported for the experiments.

The file is a dictionary with one key “channels” that contains a list of dictionaries. Each dictionary in the list represents a custom channel class to be imported.

The dictionaries describing the channels must have the following keys:

• “name”: the name of the channel class to be imported.

• “package”: the package where the channel class is located.

Usually, users define their own classes and import them in the “channels.yaml” file.

Example of a “channels.yaml” file:

channels:
  - name: "FibreChannel"
    package: "my_simulation.channels"
  - name: "OpenSpaceChannel"
    package: "my_simulation.channels"
# More channels can be added here

In many cases, omnetpypy users do not need to create custom channels, as the package already provides a built-in Channel class that can be used to model simple bidirectional channels with fixed delay and loss rate.
