The performance of content distribution on the Internet is crucial for many services. While popular content can be delivered efficiently to users by caching it using content delivery networks, the distribution of less popular content is often constrained by the bandwidth of the Internet path between the content server and the client. Neither can influence the selected path and therefore clients may have to download content along a path that is congested or has limited capacity. The authors describe UKAIRO, a system that reduces Internet download times by using detour paths with higher TCP throughput.
