The Internet becomes more and more integrated into everyday life these days. Reasons may be increasing data transfer rates and decreasing connection fees. Increasing data transfer rates on the client-side cause a widespread usage of peer-to-peer techniques that balance network load between servers and clients. Especially when distributing content to a multitude of customers, usage of peer-to-peer mechanisms comes in handy. Another main impact of the Internet nowadays is an increasing appetite for on-demand content which leads to entertainment devices providing customers with on-demand media from the Internet in their living rooms.
