The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. A time adjustment may be determined and applied to uplink transmission timing of a cell group. A transmission timing difference between a first cell group and a second cell group may be determined. If the transmission timing difference exceeding a threshold, one or more devices may stop transmitting uplink signals via one or more secondary cells and/or may stop applying the timing adjustment for a cell group.

Methods and systems for improving accuracy, speed, and efficiency of context-aware pattern matching are provided. According to one embodiment, a packet stream is received by a first stage of a hardware accelerator of a network device. A pre-matching process is performed by the first stage to identify a candidate packet that matches a string or over-flow pattern associated with access control (e.g., IPS or ADC) rules. A candidate rule is identified based on a correlation of results of the pre-matching process. The candidate packet is tokened to produce matching tokens and corresponding locations. A full-match process is performed on the candidate packet by a second stage of the hardware accelerator to determine whether it satisfies the candidate rule by performing one or more of (i) context-aware pattern matching, (ii) context-aware string matching and (iii) regular expression matching based on contextual information, the matching tokens and the corresponding locations.

The present invention relates to data transmission over HTTP communication networks, for instance data streaming. A method of transmitting data between a server and a client, comprises, at the server: receiving, from the client, an HTTP request to obtain first data, wherein the HTTP request includes first data identifying information allowing identification of the first data on the server and includes one or more additional header fields containing an indication relating to pushing second data; retrieving and sending the first data to the client; and sending acknowledgment data to the client device, the acknowledgment data being representative of the indication relating to pushing second data.

Systems and methods for neutral application programming interfaces are disclosed. In one embodiment, the disclosure relates to a system for neutral application programming interfaces. The system may comprise a device. The device may be configured to receive a request. The request may comprise an outer payload and an inner payload. The device may be further configured to parse the outer payload based on a common definition of the outer payload. The device may be further configured to extract information of an action from the outer payload. The device may be further configured to parse the inner payload based on a definition of the action. The device may be further configured to process the action.

Methods, systems, and computer readable media for generating and using a web page classification model are disclosed. The method may include identifying a plurality of web pages for generating a web page classification model, assigning a label to each of the plurality of web pages, accessing Transmission Control Protocol/Internet Protocol (TCP/IP) traffic traces associated with downloading content from each of the plurality of web pages, processing TCP/IP headers from the TCP/IP traffic traces to identify and extract features that discriminate between the labels, that are uncorrelated and whose discriminatory accuracy remains stable across time and/or browser platform. The method may further include generating a web page classification model by training a trainer to learn a combination of the features that accurately discriminates between the labels. The model is usable to classify unlabeled web pages by applying the model to TCP/IP traffic traces used to access the unlabeled web pages.

Certain aspects of the present disclosure provide compression schemes for relaying prior to decoding. A method that may be performed by a wireless relay node includes receiving, from a transmitter node, a first packet intended for a receiver node, compressing pre-decoded samples of the first packet according to a compression scheme, and transmitting, to the receiver node, a second packet including the compressed pre-decoded samples.

A system for providing an enhanced acknowledgement (ENH-ACK) frame is configured to receive an incoming packet transmitted by an external device, determine that an ENH-ACK response is required based on a MAC header of the incoming packet schedule transmission of the ENH-ACK frame to the external device in accordance with a standard turnaround time limit relative to receipt of the incoming packet, determine contents of one or more packet processed fields of the ENH-ACK frame and populate the one or more packet processed fields, and complete transmission of the ENH-ACK frame with the populated packet processed fields.
