Content Distribution Network (CDN) technology has been proposed to deliver content from content nodes placed at strategic locations on the Internet. However, only companies or organizations, who can pay for the services of CDNs, have the privilege of using CDNs to distribute their content. Individual users (peers) have to resort to more economical peer-to-peer (P2P) technologies to distribute their content. Although P2P technologies have demonstrated tremendous successes, they have inherent problems such as the instability and the limited bandwidth of peers. In this paper, we propose a new approach to build bandwidth bounded data distribution trees inside a CDN so that external peers can leverage the power of a CDN’s infrastructure for distributing their content. Our performance evaluation shows that, with some limited help from a CDN, the content distribution time among peers can be speeded up from 1.5 to 3 times.
