Application of fountain forward error correction codes in multi-link multi-path mobile networks

摘要

A method and apparatus are described including receiving content, applying fountain codes to symbols of the content to generate fountain encoded symbols at one of a transport layer and an application layer and transmitting the generated fountain encode symbols via a mobile network that uses a multi-link delivery system. Also described are a method and apparatus including receiving data packets of fountain encoded symbols via a mobile network that uses a multi-link delivery system, decoding the received data packets of fountain encoded symbols to content data, attempting to recover any corrupted content data and determining if the content data was recovered.

1. A method comprising the steps of:
applying fountain codes to symbols of a content to generate a first set and a second set of fountain encoded symbols; and transmitting the first set and the second set of generated fountain encoded symbols via a multi-link network, wherein the first set of generated fountain encoded symbols having a smaller number of edge degrees than the second set of generated fountain encoded symbols, and the first set of generated fountain encoded symbols are transmitted over a first network link having a shorter delay and lower data loss than a second network link used to transmit the second set of generated fountain encoded symbols.
