1. ) A method comprising:

  • receiving, by a fractional-storage CDN server, erasure-coded fragments associated with content;

    storing the fragments on the CDN server;

    copying at least some of the fragments stored on the CDN server to bandwidth amplification devices that are together approximately capable of providing a required bandwidth amplification factor; and

    providing either the original fragments or the copies to assembling devices, to be used for content reconstruction together with any other unique erasure-coded fragments, at a throughput of up to the aggregated bandwidth of the CDN server and the bandwidth amplification devices.
