Abstract:
1. A system, comprising: a plurality of assembling devices and a plurality of fractional-storage CDN servers; the assembling devices configured to obtain decodable sets of erasure-coded fragments associated with segments of streaming contents, from the fractional-storage CDN servers, while following segments of the same contents are on-the-fly essentially sequentially encoded into erasure-coded fragments and distributed to the CDN servers; each fractional-storage CDN server configured to store at least one erasure-coded fragment but less than the minimum data required to reconstruct the segments; wherein different mixtures of contents can be obtained by the assembling devices until the aggregated bandwidth used by the assembling devices to obtain the fragments from the CDN servers exceeds at least 85% of the total fragment delivery bandwidth of the CDN servers.
