Dds vs multicast
WebIn order to minimize the mulsticast traffic, Fast DDS only uses multicast for the PDP by default, switching to unicast communication for EDP. Additionally, Fast DDS provides solutions to avoid multicast discovery: Configuring initial peers so that the node can set unicast communication with them. WebThe Data Distribution Service (DDS) middleware does not use a broker in the middle. Instead, each publisher and subscriber in the pub/sub system shares meta-data about each other via IP multicast. The publisher and the subscribers cache this information locally and route messages based on the discovery of each other in the shared cognizance.
