Predictive Peer Determination For Peer-to-Peer Digital Content Download

摘要

Each computing device in a peer-to-peer network stores particular digital content. A computing device in the peer-to-peer network includes a peer prediction system that obtains an indication of digital content that has not been downloaded to the computing device but is predicted to be downloaded by the computing device in the future (e.g., in response to a user request for the digital content). The peer prediction system obtains a list of peer computing devices in the peer-to-peer network that have at least part of the digital content, and communicates with those peer computing devices to determine connectivity information for each of those peer computing devices. The computing device maintains a record of this connectivity information, and in response to a subsequent user request to download the digital content, uses the maintained record to determine which peer computing devices to access to obtain the digital content.

主权项

1. A computing device comprising:
a peer identification module configured to determine, prior to receiving a download request for digital content that is predicted to be downloaded to the computing device, a set of peer computing devices that have the digital content that is predicted to be downloaded to the computing device; a peer connectivity determination module configured to communicate with each of one or more peer computing devices in the set of peer computing devices to determine connectivity information for each of the one or more peer computing devices; a peer prioritization module configured to determine a subset of the set of peer computing devices to use as source devices for the digital content; and a digital content retrieval system configured to access, in response to receiving the download request, one or more of the subset of peer computing devices to retrieve the digital content from the one or more of the subset of peer computing devices.
