Abstract

With an enhanced client computer performance and network bandwidth, peer-to-peer (P2P) content distribution networks are receiving much attention. However, along with the popularization of P2P content distribution networks, inter- Internet Service Provider (ISP) traffic and ISP costs are increasing, and pose an impediment for making a potential P2P content distribution network social infrastructure. This paper presents a method to constitute P2P content distribution networks and a reduction in ISP costs by considering the form of the ISP interconnection in its distribution. Results from our simulations show that our proposal achieves a reduction in ISP costs and distribution time, regardless of the number of peers joining a P2P network and the capacity of its content.
