摘要： A transactional file system wherein multiple file system operations may be performed as a transaction. An application specifies that file system-related operations should be handled in a transaction, and the application is given a file handle associated with a transaction context. For file system requests associated with a transaction context, a file system component manages operations consistent with transactional behavior. The component provides data isolation by providing multiple file versions, such that transactional readers do not receive changes until after the transaction commits and the reader reopens the file. The component also handles namespace logging operations in a multiple-level log that facilitates logging and recovery. Namespace isolation is provided until a transaction commits via isolation directories, whereby until committed, a transaction sees the effects of its own operations but not the operations of other transactions. Transactions over a network are also facilitated via a redirector protocol.

摘要： Real-time communication of multimedia data over heterogeneous networks that may include constant delay networks, variable delay networks that have a common reckoning of time, and variable delay networks that do not have a common reckoning of time. If there are any variable delay networks in which there is no common reckoning of time in the heterogeneous networks, a common reckoning of time is established in each of those networks. Then, a constant delay network is emulated for each variable delay network using the specific common time reckoning present in each variable delay network.

摘要： A group identifier represents an association between each of a number of different abbreviated namespace identifiers with a corresponding hierarchical namespace (e.g., an XML namespace). A hierarchically-structured document (e.g., an XML document) is accessed by a computing system that determines that the group identifier is associated with the hierarchically-structured document. Hence, when using the abbreviated namespace identifiers in the hierarchically-structured document, the computing system knows that the corresponding namespace is associated with the designated portions of the hierarchically-structured document. Also, a schema description language document (e.g., an XSD document) may specify multiple target namespaces for a single element. Accordingly, groupings of elements may be included in different namespaces to creating overlapping or even nested namespaces.
