  • Patent number: 10237207
    Abstract: An apparatus and method for storing data traffic on a flow basis. The apparatus for storing data traffic on a flow basis includes a packet storage unit, a flow generation unit, and a metadata generation unit. The packet storage unit receives packets corresponding to data traffic, and temporarily stores the packets using queues. The flow generation unit generates flows by grouping the packets by means of a hash function using information about each of the packets as input, and to store the flows. The metadata generation unit generates metadata and index data corresponding to each of the flows, and stores the metadata and the index data.

  • Patent number: 9781224
    Abstract: A content transmission system includes: a central control device to receive a content packet to be provided to a client device from a content server, store chunks divided from the received content packet together with corresponding chunk identifiers, check duplication of the divided chunks, and transmit the chunk identifier and flow information of a duplicate chunk to a local caching device instead of transmitting the content packet corresponding to the duplicate chunk; and the local caching device to: receive the chunk identifier and the flow information of the duplicate chunk from the central control device, and transmit the content packet corresponding to the received chunk identifier and previously stored to the client device.

  • Patent number: 9342366
    Abstract: An intrusion detection apparatus and method using a load balancer responsive to traffic conditions between a central processing unit (CPU) and a graphics processing unit (GPU) are provided. The intrusion detection apparatus includes a packet acquisition unit, a character string check task allocation unit, a CPU character string check unit, and a GPU character string check unit. The packet acquisition unit receives packets, and stores the packets in a single task queue. The character string check task allocation unit determines the number of packets in the packet acquisition unit, and allocates character string check tasks to the CPU or the GPU. The CPU character string check unit compares the character strings of the packets with a character string defined in at least one detection rule inside the CPU. The GPU character string check unit compares the character strings of the packets with the character string inside the GPU.

  • Patent number: 8376327
    Abstract: A strut assembly forming an upper part of a cylinder joined to a wheel is joined to a vehicle body via an insulator and joining member, an airtight chamber space is formed by a strut cover joined to a spring body joined to a damper rod drawn from the cylinder, whereby a CDC type damper with the chamber space of which air pressure is controlled in order to vary the movement characteristic depending on movement of a tire and a damper joined to an inner space of the spring body has an urethane made damper guider having dug air channels where air moves even in a state where the damper is in close contact with the damper rod.

  • Patent number: 7895653
    Abstract: Embodiments of the present invention provide a method, system and computer program product for bot detection for network distributable markup. In accordance with an embodiment of the present invention, a page request for distributed markup can be processed to incorporate embedded fragment within the requested page. For instance, the fragment can include a script enabled to detect human activity within the requested page such as a mouse movement. Alternatively, the fragment can include an extraneous markup artifact. The requested page subsequently can be returned to the requestor and the embedded fragment can be monitored to detect the presence of a bot depending upon the activation of the artifact. For example, where human activity can be detected within the page or where the extraneous markup artifact becomes activated despite the extraneous nature of the artifact, a human requestor can be concluded.

  • Patent number: 6657572
    Abstract: A digital noise-shaping filter with real coefficients for delta-sigma data converters used in a digital amplifier, 1-bit digital/analog converter, 1-bit analog/digital converter and the like, and a method for making the same. The present digital noise-shaping filter has improved noise suppression performance and system stability and reduced calculation complexity. To this end, the digital noise-shaping filter comprises a noise transfer function expressed by NTF(z)=−1+a1z−1+a2z−2+&Lgr;+aNz−N. The noise transfer function has optimum real coefficients or real coefficients approximating them.
