Peer Accelerated Content Delivery
BitTorrent DNATM is the next step in the evolution of digital content delivery; it combines the extreme efficiency and organic scalability of peer networking with the control and reliability of a traditional content delivery network (CDN). BitTorrent DNA uses one or more existing origin servers or CDNs to seed a managed peer network.

Use of the peer network is tightly controlled by a specialized tracker operated by BitTorrent, Inc. and accessible to BitTorrent DNA customers through a web-based dashboard that provides control and reporting tools.

Assured Delivery
BitTorrent DNA is designed to complement existing delivery mechanisms, making the best use of both peer and infrastructure resources. Customers using BitTorrent DNA for downloads may associate with each object a quality of service (QoS) parameter that defines a required minimum bit rate. When BitTorrent DNA is used for streaming media, QoS is set automatically to ensure smooth playback with no buffering interruptions, while still making the most use of the peer network. Throughout the download process, BitTorrent DNA carefully balances its use of peer and CDN or server resources, downloading from all, in parallel, to meet per-object or streaming media QoS requirements.

Organic Scalability
By unobtrusively harnessing end-users’ unused network capacity, BitTorrent DNA scales organically with demand, providing capacity exactly where and when you need it. Need delivery capacity in some particular corner of the world? BitTorrent DNA will give you capacity there. Do you occasionally experience unexpected spikes in demand that strain your delivery infrastructure? BitTorrent DNA automatically scales its delivery capacity with demand to ensure a consistently high-quality user experience.

Advanced Bandwidth Management
BitTorrent DNA runs quietly in the background with minimal impact to the end-user experience. Our proprietary transport technology leverages the full available network capacity of all paths without disrupting other applications. By detecting the presence of other applications, computers, and devices sharing the consumer’s broadband connection, BitTorrent DNA automatically moderates its use of the network to ensure that web browsing, voice over IP (VoIP), Internet gaming, and other applications are not disrupted.

Friendly to Service Provider Networks
BitTorrent DNA contains a number of enhancements to mitigate the impact of peer networking on service provider networks. These enhancements include: BitTorrent’s sophisticated congestion-avoiding transport technology; an intelligent peer selection algorithm that prefers peers on the same LAN, network, or AS; and work with vendors of BitTorrent caching products to support local cache discovery. By keeping traffic local and non-congestive, BitTorrent DNA reduces long-haul and peering traffic for service providers, while improving the end-user experience.

Multi-CDN Acceleration
BitTorrent DNA is designed to complement existing delivery mechanisms, including content delivery networks (CDNs) and traditional web servers. To provide maximum flexibility and robustness, BitTorrent DNA can seed its managed peer network from multiple CDNs in parallel.

Multi-CDN Analytics
BitTorrent DNA’s client-side telemetry and web-based dashboard provide performance visibility across all deployed content delivery solutions, including third-party CDNs. With BitTorrent DNA, you see accurate reports of the actual performance experienced by your end users.
