Abstract
A method includes receiving information from a tracker device indicating that a plurality of devices is associated with a media content item. The method also includes establishing peer-to-peer sessions with a first group and a second group of the devices, selecting the first group based on a first bit-rate satisfying a threshold bit-rate, and sending a first request, via a first peer-to-peer session, to a first device of the first group. The media content item is divided into a plurality of chunks. The first request identifies a first chunk. The method also includes receiving the first chunk, modifying the threshold bit-rate based on a number of buffered chunks, and selecting the second group based on a second bit-rate satisfying the modified threshold bit-rate. The method also includes sending a second request to a second device of the second group. The second request identifies a second chunk.
