Video streaming now amounts to the majority of traffic in the Internet. Media streaming relies on large-scale content distribution networks (CDNs), that incur significant costs to build or use. P2P distribution of video content reduce reliance on CDNs and costs. Unfortunately, P2P distribution is fraught with QoE problems, specially during flash crowds or in scenarios where users have limited bandwidth to contribute to the overlay. In this paper, we propose a new P2P overlay construction mechanism to speed up peer joining during flash crowd events while preserving QoE for peers already in the overlay. We also show that our techniques work on resource-constrained overlays where a fraction of peers lack resources to contribute to the overlay, e.g., users on mobile devices and metered connections.
