As a way to turn multicast operations more efficient, specially when there are losses in the media, Digital Fountain codes were created. These consist in sending an unlimited stream of symbols and, by placing the intelligence in the reception, recovering the original signal by decoding a certain number of them, and avoiding the need to control which packets were received or loss.
