US Classification:

Abstract:

A system and method for performing policy-based storage management using data related to access frequency and file attribute accumulation. A switch device provides transparency for transactions between a client and a storage network. The transparency allows objects (e. g. , files or directories) to be moved (e. g. , migrated) on the storage network without affecting a reference to the object used by the client (e. g. , a file handle). A monitoring module generates accumulation data associated with the transactions for use in policy-based management. The accumulation data can describe uses of the file such as how often certain files are accessed, modifications to files such as creations of new directories or files, and other uses.

International Classification:

G06F 15/173

US Classification:

709226

Abstract:

Systems and methods to customize a namespace using a synthetic namespace. A NAS switch provides file migrations in a NAS storage network that are transparent to the clients. The NAS switch file handles are used to customize a namespace. More specifically, a synthetic namespace is generated from one or more file location tables that map the switch file handles to NAS file handles. The NAS file handles are independent of a physical export containing the objects referred to by the NAS file handles. In one example, the synthetic namespace presents a home directory corresponding to a location of a user.

Filed:

Apr 15, 1997

Appl. No.:

8/842605

Inventors:

Chi Wong - Palo Alto CA

Assignee:

Nortel Networks Corporation

International Classification:

H04M 3493

US Classification:

379 8803

Abstract:

A voice-dialing apparatus and method extracts semantic features from a speech signal and transmits a set of semantic feature characteristics over a telecommunication control channel to a remote speech recognition processor. Once received, the remote speech recognition processor uses the feature set to retrieve a name and number corresponding to the audio signal received from the user and to automatically dial the number for the user.

Appl. No.:

8/623635

Inventors:

Chi Wong - Palo Alto CA

Assignee:

Northern Telecom Limited - Montreal

International Classification:

H04M1/64

US Classification:

379 8803

Abstract:

A method of reducing the perplexity of a speech recognition vocabulary and dynamically selecting speech recognition acoustic model sets used in a simulated telephone operator apparatus. The directory of users of the telephone network is subdivided into subsets wherein each subset contains the names of users within a certain location or exchange. A speech recognition vocabulary database is compiled for each subset and the appropriate database is loaded into the speech recognition apparatus in response to a requested call to the location covered by the subset. Furthermore, a site-specific acoustic model set is dynamically loaded according to the location of a calling party. An apparatus for carrying out the method is also discussed.
