Abstract

Hybrid pull and push based streaming selectively performs a pull-based distribution of a stream to a first point-of-presence (“PoP”) of a distributed platform having low demand for the stream, and a push-based distribution of the stream to a second PoP of the distributed platform having high demand for the stream. The push-based distribution may be used to prepopulate the second PoP cache with the live stream data as the live stream data is uploaded from an encoder to a source PoP of the distributed platform, and before that live stream data is requested by the second PoP. In doing so, requests for the live stream data received at the second PoP may result in cache hits with the requested live stream data being immediately served from the second PoP cache without having to retrieve the live stream data from outside the second PoP.

Claims20

Dependent claims

A method comprising:

determining that demand for a first stream being uploaded to a source in a distributed platform is less than a threshold;
performing a pull-based distribution of the first stream based on the demand for the first stream being less than the threshold, wherein performing the pull-based distribution comprises providing a segment of the first stream from the source to a destination in the distributed platform in response to the source receiving a request for the segment from the destination;
and
determining that demand for a second stream being uploaded to the source is greater than the threshold;
and
performing a push-based distribution of the second stream based on the demand for the second stream being greater than the threshold, wherein performing the push-based distribution comprises prepopulating a cache at a destination in the distributed platform by forwarding data for a segment of the second stream from the source to the destination prior to the source receiving a request for the segment of the second stream from the destination.
