By building a P2P Content Distribution Network (CDN), peers collaborate to distribute the content of underprovisionned websites and to serve queries for larger audiences on behalf of the websites. This can reveal very challenging, given the highly dynamic and autonomous participation of peers. Indeed, the P2P-CDN should adapt to increasing numbers of participants and provide robust algorithms under churn because these issues have a key impact on performance. Also, the distribution of tasks and content over peers should take into account their interests in order to give them proper incentives to cooperate. Finally, the routing of queries should aim peers close in locality and serve content from close-by providers to reduce network overload and achieve scalability. We have previously proposed a locality and interest-aware P2P-CDN, Flower-CDN, that lacks efficient management of robustness and scalability. In this paper, we focus on these crucial shortcomings and propose PetalUp-CDN. The performance evaluation wrt. scalability and churn shows highly significant gains.
