摘要： A method and apparatus for dynamically balancing the loading of video data storage devices facilitates the transfer of video data by acquiring a listing of locations and loading of all segments of a requested video data. Those storage devices containing copies of each segment of the video data having a least loading are selected. If the loading of the storage devices exceed their maximum capacity, the segment is divided into sub-segments and stored to storage devices with minimum loading. The presence of all segments of the requested video data is determined. If there are missing segments of the requested video data, each of those missing segments is assigned a file identification and file location, such that those missing segments are retrieved from a back-up storage device and assigned to data storage devices having the least loading for transfer to a requesting computer system.

摘要： A system, method and computer program storage device providing event and/or state sharing support e.g., for building object-oriented interactive groupware in wide-area distributed environments (such as the Internet). For collaborative applications programmed using events, mechanisms are provided for sharing application-specific events. For example: an event based programming model allows applications to post an event and triggers corresponding ERUs (Event Reaction Unit) in reaction to a received event; preconditions for control activation of ERUs; and event consistency policy objects implement application specified event consistency model. Some policy examples are: a policy in which event order is not guaranteed, but all events are guaranteed to be sent to the ERUs eventually; and a policy that first triggers local ERUs and then posts the event to the server. An out-of-order event is detected using the event notification from the server; and an automatic detection of out-of-order events seen by ERUs in the local workstation in this optimistic event execution model. For applications requiring support for state sharing, an asynchronous model for updating replicated state, which supports atomicity of updates across multiple shared objects is described. Coupled with a flexible marshaling framework, this allows existing application data-structure classes to be easily extended and made shareable. To solve the problem of replica consistency, a novel combination of three mechanisms is used: global locks; detection of incorrect update ordering; and cloning a subset of the shared objects for state re-initialization. To reduce network load due to fine-grained user interaction, a framework for application specified event batching, called Late Event Modification (LEM), enhances the event interface to allow applications to modify the event objects after posting them to the set.

摘要： A video distribution system is implemented on a hierarchical parallel processing system that has clusters that are automatically formed from nodes of computer processing systems. Each cluster has a cluster supervising processor or group leader system that controls cluster configuration, fault detection and isolation, and data distribution. The group leader is determined according to a priority determined during the configuring of the hierarchical parallel processing system. The clusters are able to be reconfigured to allow removal and addition of nodes without impact on operation of the parallel processor system. The cluster provide a node status or heartbeat message that which provides detection and isolation of failure of nodes and disk storage devices within a cluster. The nodes within the cluster are able to join or leave a cluster and not affect performance.

摘要： An video data object distribution system for transfer of video data objects includes a network of digital data file servers. The network of digital data file servers communicate with a client system to transfer video data objects. A scheduling apparatus schedules the transfer of the video data objects. A client streaming device within the client begins transfer of a first segment such that the video data object is started streaming of prior to reception of a totality of the first segment. An ordered sequential transfer device orders and sequentially transfers segments of the video data object to the client system. The preemption device allows persistent video data object transfer of video data object without resending the video data objects. A hierarchical caching controller copies segments of any of the video data objects from a central distribution server to any of the network of data file servers.
