Abstract
Embodiments of network devices for content distribution are described. In some embodiments, an edge network device integrates network coding for content distribution with erasure coding for data storage. Embodiments of methods of integrating network coding and erasure coding are also disclosed. In some embodiments, an edge network device can determine content distribution and storage for content based on one or more penalty functions that assess storage capacity, computational power, user demand, and/or network bandwidth for optimal resource usage. In some embodiments, an edge network device creates fragments of content and transmits a subset of the fragments for early distribution. In response to a user request for the content, the edge network device can transmit the remaining fragments to the user device for the user device to reconstruct the original content.
