High robustness against churn and resilience towards adverse behavior are the key requirements for reliable Peer-to-Peer streaming systems. Their highly inter-dependent nature, based on the cooperative service delivery between all peers, necessitates a systematic and structural resilience, which, in their design of self-organization and decentralized control, is very challenging to assure. Reliable services, and hence a structural resilience, still are a vital prerequisite for any commercial deployment of P2P-based live streaming systems or IPTV infrastructures. We propose an entirely distributed, Motif-based topology optimization to this end. Concise comparisons show that it creates topologies almost as resilient as the current state of the art, yet causing significantly less, almost negligible overhead in both computation and messaging, and still offering even better protection of information on the overall system.
