Abstract
A technique can be used to obtain content (e.g., a live feed, pre-positioned content, etc.) from a content-originating device (a content source). The technique involves identifying a tree-based location-path having a series of locations which leads from the computerized device to the content-originating device. Each location includes a set of devices, and the set of devices of at least one location includes multiple devices. The technique further involves selecting a device-path from the computerized device to the content-originating device based on the identified location-path, and acquiring the content from the content-originating device from at least one of the devices along the selected device-path. The selected device-path includes at least one device of each location of the series of locations.
