    摘要: A method of defining extent for storing a plurality data streams having different bit rates. The method calculates the size of the extent for a given data stream then periodically inserts at least one null packet into the extents to enable any bit rate to be able to be stored using a fixed extent size for the stream.

    摘要: A method of data management for efficiently storing and retrieving data in response to user access requests. The architecture comprises a plurality of disk drives over which data is distributed, and a plurality of processors, each of which is assigned to a subset of the disk drives in a modular fashion. The server architecture employs dynamic data management methods and load-balancing methods to assign user requests to processors. The modular server architecture, in combination with the dynamic data management and load balancing methods, provides both good performance (i.e., low expected-case access times and high disk bandwidth), and fault-tolerance. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular programs.

    摘要: A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.

    摘要: A method providing integrity analysis of content data streams within an information distribution system. On-demand content is divided into a plurality of content portions to be severally distributed among disk drives of an array of disk drives. A data structure is used for dividing the content into the plurality of content portions. Method is used to check integrity of content prior to provisioning thereof.
