Abstract
Using a distributed storage to its maximum bandwidth including the following steps: for each group of at least one assembling device, selecting a subgroup of fractional-storage CDN servers according to at least one criterion, whereby a plurality of server subgroups are selected for a plurality of assembling device groups. And retrieving, using a pull protocol, by the assembling devices from the subgroups of servers, erasure-coded fragments associated with multiple segments of contents, until the aggregated bandwidth used for retrieving the fragments approaches the aggregated bandwidth of the servers included in the subgroups, and as long as the aggregated bandwidth used for delivering each segment does not exceed the aggregated bandwidth of the servers storing the fragments generated from the segment.
