Currently, the most widespread model for data transfer uses a client-server paradigm (e.g. Content Distribution Network, or CDN). A totally different approach to content delivery is Peer-to-Peer (P2P) technology. While both technologies have proven their validity, a series of limitations affect each one: deploying CDN servers is expensive, and the overall transfer speed depends on the distributor's network bandwidth and processing power of the machine. Even though P2P architectures avoid these problems, for a successful data transfer they require a sufficient number of seeding clients, making them unreliable. In this paper, we propose a hybrid content delivery solution that tries to leverage the advantages of both approaches, while mitigating their weaknesses. This architecture aims at offering a viable data transfer model, with superior download speed, increased reliability and affordable resources.
