    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.

    Abstract: A method and network apparatus for downloading data from the network apparatus to a mobile device in anticipation of the mobile device entering a black spot zone. The network apparatus determines that the mobile device has entered a predetermined tracking zone related to the black spot zone and gathers information for defining a download zone for the mobile device taking into consideration a time necessary for downloading the data to the mobile device, and a predicted time interval until the mobile device enters the black spot zone. The network apparatus then sends the data to the mobile device when the mobile device enters the download zone.
