Free registration required

Executive Summary

With growing demand for high-quality multimedia content, content providers face enormous pressure to scale the serving capacity. Peer-to-peer content distribution is a natural low cost option to scale system capacity. In a P2P CDN model, content providers serve content using a small number of "Official" seeder nodes and rely on participating users to act as individual seeders for others in the system. Although P2P CDNs have the potential to drastically reduce the required serving capacity of official seeders, they must address the challenge of incentivizing users to stay online in the P2P network and act as seeders.
