Imagine SD-WAN like a traffic police officer standing in the middle of a busy crossroad, and network frames as road vehicles. His primary task is to regulate traffic so that everyone gets to his work as soon as possible. The SD-WAN will forward frames to the right path according to their destination. However he must give priority to emergency services. Likewise SD-WAN will treat delay sensitive frames like voice and video, where loss matters, with high priority and guide them to an unblocked way.
