Abstract:
An application framework may include a cloud-independent application manager, a cloud-independent content services manager, and cloud-independent content services servers. The framework may dynamically install and manage scalable, multi-tenant applications in a cloud, and may scale the applications, as needed. The application manager may receive and handle requests to install application domains and configurations thereof, and may receive and respond to requests for information about servers on which installed methods are available. The content services servers may execute installed methods, using underlying resources of the cloud, through a cloud-specific SPI. The content services manager and application manager may work together using shared cloud storage to provide scalable content services at a very large scale. In the context of the framework described herein, an “application” may be defined by methods bundled into configurations, and by various cost-based and/or performance-based rules that specify how server instances providing those methods are to be managed.
Abstract:
Enhanced wireless speeds are obtained using multiple transmission beams. In one example, a transmitter has a signal processor to receive a plurality of data streams, a plurality of analog converters each coupled to the signal processor to receive the plurality of data streams from the signal processor and to modulate the data streams onto carrier waves, and a plurality of phase shifters each coupled to an analog converter to each receive a modulated stream. A first antenna is coupled to more than one of the plurality of phase shifters to receive the modulated data stream from each phase shifter and transmit it on its respective carrier wave, and a second antenna is coupled to receive at least one modulated data stream and transmit it on its respective carrier wave.
Abstract:
A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element intercepts data packets comprising network layer or transport layer headers having an address of a destination which destination differs from the network element. The network element determines whether information contained in layer 2-4 headers of the data packet satisfies specified criteria. If the information satisfies the specified criteria, the network element directs the data packets to a blade of the network element that performs processing based on an application layer message at least partially contained in the data packets. If the information does not satisfy the specified criteria, the network element forwards the data packets towards the destination without sending them to the blade.

Abstract:
A method is disclosed by which network elements such as packet routers and packet switches guarantee the delivery of application layer messages within a network. According to one aspect, a first network element retrieves an application layer message from a source message queue, adds a message identifier to the application layer message, encapsulates the application layer message into data packets, and sends the data packets toward a destination application. A second network element intercepts the data packets, determines the application layer message from payload portions of the data packets, determines the message identifier from the application layer message, stores the application layer message in a destination message queue, generates an acknowledgement message that contains the message identifier, and sends the acknowledgement message toward a source application. The first network element intercepts the acknowledgement message and concludes that the application layer message within the matching message identifier was successfully delivered.
Abstract:
A system is provided to deploy a computing application on a cloud using a service provider interface. The system comprises a launch request detector, a service provider interface selector, and a launcher. The launch request detector may be configured to detect a request to launch a server computer system within a virtualization service. The server computer system, in one example embodiment, comprises a computing application and a service provider interface layer. The service provider interface selector may be configured to determine an implementation of the virtualization service and access a service provider interface associated with the implementation of the virtualization service. The launcher may be configured to complete launching of the server computer system within the virtualization service, utilizing the selected service provider interface.
Abstract:
A radio frequency (RF) transmitter is coupled to and controlled by a processor to transmit data. A physical layer circuit is coupled to the RF transmitter to encode and decode between a digital signal and a modulated analog signal. The physical layer circuit comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). The low rate channels generated by the low rate physical layer circuit (LRP) share a same frequency band as a corresponding high rate channel generated by the high rate physical layer circuit (HRP).

Abstract:
A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element receives user-specified input that indicates a particular message classification. The network element also receives one or more data packets. Based on the data packets, the network element determines that an application layer message, which is collectively contained in payload portions of the data packets, matches the particular message classification. The network element processes at least a portion of the message by performing, on behalf of the application to which the message is directed, and relative to at least the portion of the message, one or more actions that are (a) specified in the user-specified input and (b) associated with the particular message classification.
Abstract:
An optical duobinary transmitter. The transmitter uses a half-rate precoder, half-rate non-linear modulation drive circuits and a multiplex modulator for generating duobinary modulation on an optical signal from which full-rate data can be detected without decoding.
