Performance evaluation in trust enhanced decentralised content distribution networks

Content Delivery Networks (CDN) have become a key architecture in the provision of today's Internet based services like Video on Demand. A higher degree of decentralisation in the implementation of CDNs is the next possible step to ensure quality levels but also to be more Internet Service Provider (ISP) friendly in the operation of CDNs. This paper discusses the impact of trust enhancements into peer-to-peer (P2P) based content distribution protocols using the BitTorrent protocol as an example.
