Abstract
A content delivery system which supports fragment requests without specifying the source address, including an assembling device, a relay server, and fractional-storage servers. The assembling device issues a client-request to receive enough erasure-coded fragments to reconstruct a portion of streaming content. The relay server receives the client-request, selects a plurality of fractional-storage servers that together store enough fragments to reconstruct the portion, and transmits, to the fractional-storage servers, fragment pull protocol requests for these sufficient fragments, on behalf of the assembling device. And the fractional-storage servers transmit the requested fragments to the assembling device in response to the fragment requests.
