Abstract
Techniques for sharing data among a plurality of networked devices, also referred to network nodes, are discussed. To best use an available uploading bandwidth of a device sharing data with a receiving device, a portion of the data is uploaded within the available uploading bandwidth, and another portion of the data is uploaded from another device locally caching the same data. To satisfy the minimum transmission rate of the data to the receiving device, both portions of the data are concurrently uploaded from the two devices to the receiving device. In reference to a predetermined minimum uploading bandwidth and the available uploading bandwidth, the two portions of data are interleaved and must be reassembled to recover the data for consumption in the receiving device. A size of the first portion of the data is determined by a server in view of the available uploading bandwidth a designated supplying box has.
