1. ) A method for retrieving erasure-coded fragments, comprising:

  • identifying a first group of fractional-storage servers estimated to have low response latencies in relation to an assembling device;

    retrieving, by the assembling device from a second group of fractional-storage servers, enough erasure-coded fragments needed for reconstructing approximately sequential segments of streaming content;

    while retrieving the fragments, identifying at least one server from the second group having latency higher than a certain threshold in response to a fragment pull protocol request; and

    using the fragment pull protocol to replace the identified server with at least one server selected from the first group.
