1. ) A content delivery system, comprising:

  • a large number of fractional-storage CDN servers configured to store erasure-coded fragments associated with contents; and

    a large number of assembling devices configured to obtain the fragments from sub-sets of the fractional-storage CDN servers;

    at least some of the fractional-storage CDN 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 fractional-storage CDN servers accessed via the shared link participate;

    wherein the maximum number of sub-sets in which the fractional-storage CDN 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.
