Managed P2P network with content-delivery network

摘要

A content-acquisition request is sent to a centralized management service computer via a computer network. The content-acquisition request may query the centralized management service computer for a recommended content source to provide a first digital content item. If a response to the content-acquisition request is received via the computer network and identifies a recommended peer computer of a peer-to-peer network as the recommended content source, a request to download the first digital content item is sent to the recommended peer computer via the computer network. If a response to the content-acquisition request is not received, a fallback request to download the first digital content item is automatically sent to a content-delivery network computer via the computer network.
