* The Service-ID is designed to identify the type of the communication (e.g. READ_REQUEST, WRITE_REQUEST, READ_RESPONSE, WRITE_RESPONSE, ...)
* The Service-ID is designed to identify the type of the communication (e.g. :const:`READ_REQUEST`, :const:`WRITE_REQUEST`, :const:`READ_RESPONSE`, :const:`WRITE_RESPONSE`, ...)
* The Data-ID is designed to identify the requests / responses using the same Service_ID.
.. note:: The :class:`comm_instance` needs to have at least the following interface:
* A Method :func:`comm_instance.init_channel_name` to set the channel name if needed.
* A Method :func:`comm_instance.init_channel_name` to set the channel name.
* A Constant :const:`comm_instance.IS_CLIENT` to identify that the :class:`comm_instance` is a client (True) or a server (False).
* A Method :func:`comm_instance.is_connected` to identify if the instance is connected (True) or not (False).
* A Method :func:`comm_instance.reconnect` to initiate a reconnect.
