Abstract
A system for delivering streamed content over a large digital network such as the Internet. Distributed functionality executes on nodes in the network to achieve functions such as assigning partner nodes for transfer of content to or from a target node, scheduling transfer operations among nodes, adding or removing nodes from the network, maintaining security, and other operations. Different embodiments may use one or more of the functional features. In a preferred embodiment, video content is segmented and streamed through multi-path routing. An overlay network uses nodes in partnership groups so that a target node can obtain segments from multiple sources. Partner nodes can provide the segments within a given time window, including simultaneous delivery from multiple partner nodes, so that a more reliable data stream is supported.
