The c++ discovery client periodically calls ConnectionState::Update() with ConnectionStatus::UP on publish success.
ConnectionState::Update() should check for any change in the connection state before sending the NodeStatusUVE:process_status to avoid sending the duplicate information periodically.
In python, ConnectionState.update() checks for any connection state change before sending the NodeStatusUVE.
