What is DNA?

BitTorrent DNA (BitTorrent Delivery Network Accelerator) is a program designed to speed up the viewing of streaming video, downloading software (with or without the BitTorrent protocol) and playing online video games. It does so by distributing the end users' downloads between each other. In this way, the developers intend that content providers should take less load on their servers so the end users can receive the content faster. It runs in the background whenever the operating system is running. BitTorrent DNA is different from traditional BitTorrent in that it relies on publisher HTTP servers in order to provide publishers with guaranteed minimum data delivery rate, as well as give publishers control over content delivery (peers must connect to the origin server before they can reach other peers), and collect information about content delivery to share with the publisher. The quality of the file transfer is specified in terms of a long-term average bitrate for data and in terms of meeting deadlines when streaming. It also can give bandwidth to TCP and other traffic. DNA is also different from traditional BitTorrent in that it is a UDP-based protocol that has replaced regular TCP-based bandwidth throttling with a much more sensitive bandwidth management technique.
