RB-tracker: A fully distributed, replicating, network-, and topology-aware P2P CDN

Finding a good balance between link congestion and over-provisioning for network service providers is a challenge. Recent advances in transport protocols promise a smoother transfer of bulk background data-traffic that P2P (Peer-to-Peer) file sharing systems are significantly contributing to still today. This paper focuses on reducing the link congestion, and traffic peaks originating from P2P systems by replicating data during periods of low network traffic. For this purpose, RB-Tracker is proposed as an extension of B-Tracker in order to automatically manage the overlay network and replication of content, similar to a Content Delivery Network (CDN). RB-Tracker is designed to manage autonomously a P2P network and to use state-of-the-art mechanisms, such as biased neighbor selection.
