Abstract:
Provided is an engine container configured by a workflow engine framework for a cross-domain extension, including a plurality of operators configured to interwork with a plurality of representational state transfer (REST) application programming interfaces (APIs), respectively, a runner configured to sequentially call the plurality of operators according to a request from a client, and a controller configured to control an operation of the plurality of operators and the runner, wherein each operator operates in a pipeline manner to call a corresponding REST API using uniform resource locator (URL) information transferred from the runner and to transfer a processing result obtained by processing data provided through the corresponding called REST API to a next operator.
Abstract:
Provided are a data processing apparatus and method for merging and processing deterministic knowledge and non-deterministic knowledge. The data processing apparatus and method may efficiently process various real-time and large-scale data to convert the data into knowledge by merging and processing non-deterministic knowledge and also deterministic knowledge perceived by an expert. Thus, it is possible to adaptively operate in accordance with a dynamically changing application service environment by converting a conversion rule for converting collected data generated from an application service system into semantic data, a context awareness rule for perceiving context information from given information, and a user query for searching for knowledge information into knowledge and gradually augmenting the knowledge information in accordance with an application service environment.
Abstract:
The present invention discloses a digital modulation method for providing multiple services. The method for providing multiple services comprises multiplexing bits by allocating them according to a required SNR (Signal to Noise Ratio) of each service; and modulating multiplexed bits by applying non-uniform distances among constellation symbols.
Abstract:
A soft decision detecting device in a multiple-input multiple-output (MIMO) receiving apparatus detects reception symbols from signals received through a plurality of reception antennas, calculates a variance of interference and noise of the detected reception symbols, and soft-decision-demaps the detected reception symbols by using the variance of interference and noise of the detected reception symbols to thus calculate a soft decision value.
Abstract:
The present invention provides an apparatus for optimizing traffic of packets produced in a user terminal and a remote node with a WAN link between the user terminal and the remote node. The apparatus includes a flow information table configured to have identification information about the respective packets that are managed in the apparatus, a packet processing module configured to analyze the packets to determine whether the respective packets are identified in the flow information table, and an optimization module configured to optimize the packets in compliance with the optimization option specified in the respective identified packets.
Abstract:
An OpenFlow switch in an OpenFlow environment includes an attack determination module to collect statistical information on packet processing with respect to incoming packets to be processed in the OpenFlow switch at a predetermined period interval to determine whether a DDoS attack occurs. The Openflow switch also includes an attack responding module to perceive a feature of the DDoS attack by using the incoming packets introduced into the OpenFlow switch after the determination of the occurrence of the DDoS attack and process the incoming packets in line with the perceived feature of the DDoS attack. Therefore, it is possible to determine and responds to DDos attacks in the OpenFlow switches.
Abstract:
A digital demodulation system calculates an I channel value and a Q channel value of a received signal. The digital demodulation system then changes detection levels to obtain non-uniform detection levels. The digital demodulation system then demodulates the received signal bit by bit by using the changed detection levels and the I channel value and the Q channel value.
Abstract:
Provided are a MapReduce apparatus and a MapReduce control apparatus and method. The MapReduce apparatus includes a map calculator configured to perform a map calculation, a combiner configured to aggregate and summarize map calculation results of the map calculator, a rack combiner configured to aggregate and summarize map calculation results of MapReduce apparatuses connected to the same rack switch according to a policy of a MapReduce control apparatus, and a reduce calculator configured to receive the aggregated and summarized results of the combiner or the rack combiner and perform a reduce calculation.
Abstract:
