The emergence of content delivery networks (CDN) has helped improve the efficiency of delivering streaming media. In this paper, we argue with evidence that the edge delivery paradigm behind current CDNs cannot scale up to delivering high-quality broadband video content such as DVD movies. This is because there are no sufficient and affordable bandwidth and quality of service (QoS) on the "last mile". Additionally, it is difficult to scale up edge delivery with increasing number of users and aggregate bandwidth demand in services such as video-on-demand. We describe a new architecture that extends the current CDN design with a second tier of surrogate servers. These second-tier surrogate servers, called "leaf servers", are placed inside local area networks and networked homes with broadband Internet connection. High scalability and QoS can be achieved because media content is streamed to clients by massively distributed leaf servers over the "last foot".
