Abstract
Controlling fragment load on shared links, including a large number of fractional-storage CDN servers storing erasure-coded fragments encoded with a redundancy factor greater than one from contents, and a large number of assembling devices configured to obtain the fragments from sub-sets of the servers. At least some of the servers share their Internet communication link with other Internet traffic, and the fragment traffic via the shared link is determined by the number of sub-sets in which the servers accessed via the shared link participate. Wherein the maximum number of sub-sets in which the servers accessed via the shared link are allowed to participate is approximately a decreasing function of the throughput of the other Internet traffic via the shared link.
