This Participant will discover all Participants deployed in its own local network in the same domain via multicast

Use case
========

Use this Participant in order to communicate an internal standard DDS network, such as a ROS 2 or Fast DDS network
in the same LAN.


Kind aliases

Configuration

The only configuration required to start a Simple Participant is the :term:`Domain Id`
on which it will listen for DDS communications.
