Abstract
Retrieving erasure-coded fragments associated with approximately sequential segments, including the steps of requesting a first set of the fragments, using a fragment pull protocol, by an assembling device from a plurality of fractional-storage servers, and requesting a second set of erasure-coded fragments, using the fragment pull protocol, to compensate for the fragments of the first set that failed to arrive at the assembling device. And wherein while requesting the first-set fragments associated with a certain segment, at least one compensation request is made for a second-set fragment associated with a prior segment.
