Abstract: A method for effecting the execution of an application function on an application server from a client device includes receiving from the client device at a proxy server a first message that pertains to a request to execute an application function, and that conforms to a text-based user-to-user messaging protocol, and that includes a human-readable input parameter. The method also includes authenticating a user associated with the first message origination address by sending an authentication message to the user at a message confirmation address, and receiving confirmation from the user responsive to the authentication message. If the user is authenticated, the method further includes generating a second message using the human-readable input parameter and transmitting the second message to the application server.

Abstract: Methods of data streaming from an encoder to a decoder through a connection subjected to time-varying conditions are disclosed. The connection is assigned a nominal flow rate and an encoding coefficient associated with the connection modifies the nominal flow rate to determine a permissible flow rate compatible with a time-varying state of the connection. Multiple performance characteristics are associated with the connection and corresponding sets of performance measurements taken over adaptively selected time windows are acquired. Performance metrics having one-to-one correspondence to the performance characteristics are determined and compared with lower bounds and upper bounds of respective predefined acceptance intervals. A current encoding coefficient is computed as a function of the performance metrics and used to determine the permissible flow rate. The encoder's configuration is adapted to produce an encoded signal which maximizes signal fidelity under the constraint of the permissible flow rate.

Abstract: The invention is based on the idea of managing multimedia resource reservation by a solution in which, for a first user terminal, a first media terminal is searched and reserved, and a multimedia session is started. A multimedia session request is transmitted from the first user terminal to a second user terminal via an IMS subsystem. A second media terminal is searched and reserved for the second user terminal. The information on the reserved second media terminal is transmitted via the IMS to the first user terminal, which informs the first media terminal of the reserved second media terminal. After that, real-time data traffic can be transmitted via an IP network, e.g., the Internet, between the first media terminal and the second media terminal.

Abstract: The invention relates to active star coupler based network handling of redundancy in the physical layer by transmitting a message to both regular and redundant links. In an error free case, the message is forwarded by the regular interface, while the redundant link, is blocked. Each interface is equipped with link failure detection logic. If a link failure is detected, an incoming message is blocked and the affected interface controls the interface connected to the redundant link to take over message forwarding. If the link recovers, the regular interface takes over forwarding responsibility and the redundant link is disabled.

Abstract: A method is provided for sending data packets from a server to a client. A stream of data packets from the server to the client is composed of a main stream P, a retransmission stream R, and an advance stream A. P and A are fixed when R is zero. A is zero and the sum of P and R are fixed when R is not zero or when the client has accumulated data beyond a given threshold. A packet sent by the server but not received by the client is sent again to the client a given time after it was first sent. A packet sent by the server but not received by the client is sent again to the client only if the latter has already previously received a given number of packets sent by the server.

Abstract: A computer implemented method, data processing system, and computer program product for maintaining state consistency among multiple state-driven file system entities when the file system entities become disconnected. Responsive to a distributed file system server being disconnected from a distributed file system client, a monitor is registered with the consistency management framework (CMF) for a file system. When the CMF detects access to a file in the file system, the CMF notifies the monitor of the access to the file, and the monitor stores information about state of the file. When the distributed file system server is reconnected to the distributed file system client, information about state of the file stored in the monitor is provided to the distributed file system client.

Abstract: A method for processing data is proposed, particularly image data in a medical system, in which a plurality of imaging modalities for capturing the data and their associated apparatus for locally processing and storing the data are connected to one another via a data transmission unit for the purpose of data interchange. Common data for all modalities are respectively stored locally and are coordinated with one another such that the respective modality remains active regardless of the state of the data transmission unit.

Abstract: The present invention provides a novel technique for Web-based asynchronous processing of synchronous requests. The systems and methods of the present invention utilize a synchronous interface in order to couple with systems that synchronously communicate (e.g., to submit queries and receive results). The interface enables reception of synchronous requests, which are queued and parsed amongst subscribed processing servers within a server farm. Respective servers can serially and/or concurrently process the request and/or portions thereof via a dynamic balancing approach. Such approach distributes the request to servers based on server load, wherein respective portions can be re-allocated as server load changes. Results can be correlated with the request, aggregated, and returned such that it appears to the requester that the request was synchronously serviced. The foregoing mitigates the need for clients to perform client-side aggregation of asynchronous results.

Abstract: A method of managing data center power usage based on service commitments. A power and capacity management utility measures performance characteristics of applications hosted by a data center that include power consumption and transaction processing time. When the performance characteristics are above (or below) a first pre-defined target range, the utility decreases (or increases, respectively) a clock rate and processor voltage of one or more active servers. When the performance characteristics are within the first target range and the clock speed is above (or below) a second pre-defined target range, the utility activates (or deactivates, respectively) one or more inactive (or active, respectively) servers. When the size of an inactive server pool is above a third pre-defined target range, the utility moves inactive servers to an unallocated server pool. When the size of the inactive server pool is below the third target range, the utility allocates additional servers.

Abstract: An interactive system is provided to help an operator locate the source of a data fault in an Asynchronous Transfer Mode (ATM) network. A database stores information related to data types and subsystems used by the ATM network. A processor coupled to the database uses the information stored therein to formulate a series of queries related to a selected one of the subsystems using the data type experiencing a data fault. The series of queries have a hierarchal order that sequentially inquire about operational status of the various subsystems having a relationship with the data type experiencing the data fault. A graphical user interface (GUI) coupled to the processor displays each query in accordance with the hierarchal order thereof. The GUI simultaneously displays identification of the various subsystems having a relationship with the data type experiencing the data fault.

Abstract: A method, system, and apparatus are provided for allowing users to readily obtain information associated with a selected item from a remote location. More specifically, a user at the location of the first entity operates a portable imaging device to capture an image of identifying data, such as a barcode, that identifies a selected item. The captured image is then communicated to a server operated by a second entity that is different than the first entity to obtain item information (e.g., price, availability, etc.) associated with the selected item. The item information is communicated back to the portable imaging device for display to the user while the user remains at the location of the first entity. In other embodiments, the information extracted from the captured image may also be used to forecast future purchasing activity for the selected item.

Abstract: Methods and systems of processing a data stream are disclosed. A developer may develop a service only by programming a Service Unit (SU) including a service logic (SL) and including a Service Unit Description Language (SUDL) file, so that the developer may not need to program complicated stream processing code, such as stream source connection code, network input/output (I/O) code, and buffering code.

Abstract: The popularity of web pages is monitored and used to rank the web pages retrieved in response to an Internet search. The popularity of a web page is proportionate to the number of visits to that web page. Web pages with greater popularity are ranked higher in priority. Furthermore, the score of a first web page is propagated to a plurality of second web pages to which the first web page is linked substantially in relative proportion to the popularity of the links from the first web page to each of the second web pages. Monitoring devices monitor TCP packets traversing the Internet and extract information from the TCP packets, such as the requested URI or URL, the client IP address, a server IP address and a server host name, and a referrer URI, if any. The extracted information is forwarded to a processing module that keeps track of the popularity of the web pages.
