Appl. No.:

09/385201

Inventors:

Gary J. Crosby - Bristol, GB

Assignee:

Cisco Systems, Inc. - San Jose CA

International Classification:

H04M 700

US Classification:

379219, 379 8822

Abstract:

A system and method are provided for generating normalized events from nonstandard computer telephony interface (CTI) events generated by various private exchanges or telephone switches made by various manufacturers. In one embodiment, the system of the present invention includes a processor coupled to a local interface, a memory coupled to the local interface with normalization logic stored in the memory, the normalization logic being executed by the processor. The normalization logic generates a number of normalized events relative to the operation of a call center based upon non-standard CTI events received from the specific private exchange employed. In this regard, the normalization logic includes event normalization logic to generate at least one normalized event from a non-standard CTI event. The normalization logic also includes information normalization logic to add a missing amount of information to the normalized event, thereby generating an information normalized event, and temporal normalization logic to generate at least one missing normalized event upon detecting an out of sequence information normalized event.

US Classification:

709228, 709231, 709232, 709233, 725116, 725105

Abstract:

The present invention is a system in which packet-switched (or general purpose network) multimedia data streaming is controlled based on the capabilities of a client and the preferences of a user. A server processor, coupled to the client processor over a packet-switched network, such as the Internet, receives client processor capabilities in association with a request for service for a multimedia type data transfer. The capabilities can be obtained by an application running on the client assessing the capabilities or through prompting of the user. The client capabilities include, for example, processor speed and multimedia encoders of the client. The server can also obtain the preferences of the user of the client processor and respond based on the preferences. Preferences include, for example, the quality of service of the transfer. The capabilities and preferences can be obtained via a query from the server to the client or can be automatically sent with each request.

International Classification:

H04M 1/26

US Classification:

37935501

Abstract:

A smart phonebook search method comprises collecting, from a customer, a phone number to use for a dial-up connection, filtering any national direct dialing prefix from the collected number, obtaining a country code from an operating system of the smart phonebook search, matching a pattern of a prefix of the collected number with area codes for a country of the customer to provide a closest entry for said connection, and selecting a phone number for said dial-up connection, the phone number having a customer provided area code and the operating system provided country code.

Abstract:

A content synchronization method for connected devices comprises accepting, by a central reference point, context from a connected client device, constructing, by the central reference point, at least one response in a semantic compatible with the connected device and compatible with a user of the connected device the response comprising at least one file description bundle, prioritizing, by the central reference point, download order of files described in the at least one response bundle, downloading the files described in the at least one response bundle, to the connected device in the download order, confirming complete download of the files described in the at least one response bundle, and rejecting incompletely downloaded bundles of files.

Abstract:

Present invention unity parallel processing systems and methods facilitate flexible utilization of sequential program applications in a distributed multi-computer parallel processing environment. The new unity parallel processing architecture enables multiple processing nodes (e. g. , SMPs) to perform multi-thread processing within the multiple processing nodes while providing a shared virtual global memory space. Symmetric multiprocessors run shared memory applications with modified runtime guidance directives that permit the memories to emulate a virtual global memory across the plurality of symmetric multiprocessors. Within each SMP node, programs utilize multiple threads according to directives and library calls. Across multiple SMP nodes, each SMP node is treated as a single process with one-way communication to other SMP nodes. Portions of the program data are stored in memories associated with the SMP nodes and communication of the program data across multiple SMP nodes is controlled by unity compiler directives.

International Classification:

US Classification:

395678

Abstract:

Floating point hardware register set is not given to any user level thread unless it is required to perform floating point operations. Thus, for any non-floating thread, its context does not include the floating point hardware state. This effectively reduces the amount of information to be handled when threads are swapped in the processor. During the course of a thread's execution, at the first instance of an attempt by the thread to execute a floating point instruction, the "float-unavailable" exception occurs. This, in turn, invokes the microkernel's floating point exception handler. The function of this exception handler is to make floating point available to the thread that requires it. The exception handler dynamically allocates space for saving the thread's floating point registers, initializes the registers, and turns on the "float-available" bit in its machine state register. Once a thread obtains floating point context, it continues to have it for the remainder of its life.
