Peer-to-peer networks based on hierarchies of trust

A new approach to peer-to-peer (P2P) networking is proposed, which is particularly suitable for real-time interactive multimedia communications over IP networks. This approach combines the concepts of both the hybrid and pure P2P approaches. It enables administration of P2P resources and peer privileges and allows for secure content exchange, while being scalable and robust in its performance as the P2P network grows. The administration is devolved among a ´hierarchy of trust´, which can evolve with the cooperation of peers with administrative privileges.
