Bandwidth amplification using replicated fragments, including fractional-storage CDN servers storing erasure-coded fragments associated with content; and bandwidth amplification devices storing copies of sub-sets of the fragments stored on the servers in order to increase the system's total fragment delivery bandwidth. Wherein the average bandwidth amplification device comprises much less storage space and bandwidth than the average server, and the content can be reconstructed from any combination of enough unique fragments regardless of whether these fragments were obtained from the servers or from the bandwidth amplification devices.
