Abstract

The invention relates to a method and system hardware for ingesting media content in a peer-to-peer network from a data stream. The data stream is made up of a sequence of packets of media data, and each packet is identified by a sequence identifier. The method includes commencing caching of the data packets from the data stream. A missing data packet is identified using the sequence identifiers of the packets and the size of the missing data packet is determined. A portion of the memory medium is skipped to provide a skipped portion of medium having no data cached therein. The skipped portion has a size corresponding to the determined size of the missing data packet. The missing data packet is then retrieved and inserted into the skipped portion of the memory medium. The system includes an ingestion element configured to receive the content in a data stream, to define blocks of media data that make up the content, to generate metadata associated with each block, the metadata identifying the construction of the block from the data stream, and to transmit the data stream as a multicast stream to other network nodes. The other network nodes include at least one cache element configured to construct at least one of the blocks from the multicast data stream in accordance with the metadata, and to cache the data block. The system also includes a database accessible to network nodes, the database recording a location of each of the cached data blocks in the network.
