Today, the data exchanged over Online Social Networks (OSNs) represents a significant fraction of internet traffic. However, OSN content is different from more traditional web content, as it is more likely to be generated at the edge of the network, to be exchanged within a local geographic region, and to possess a more even popularity distribution with fewer popular objects. Unfortunately, most OSNs still use largely centralized approaches to distribute content (e.g., CDNs and web caches), resulting in lower performance due to the different workload.
