  • Patent number: 7751330
    Abstract: Provided are a method and apparatus for dynamically managing hierarchical flows that more efficiently process packet traffic while maintaining compatibility with an existing packet data network in transferring both circuit traffic and packet traffic in a packet switched network. The method for dynamically managing hierarchical flows includes: receiving data packets, classifying the data packets according to attributes of the received data packets, and producing first flows; determining whether traffic of each of the first flows exceeds a predetermined bandwidth limit, and performing a packet drop process or producing second flows for first flows that exceed the bandwidth limit, according to a flow-specific policy; and performing second flow processing on the second flows according to a second flow policy. Only flows exceeding the bandwidth limit or causing congestion are hierarchically divided for management. This makes it possible to finely manage the flows without complex operations.

  • Patent number: 7729056
    Abstract: A light-condensing member includes a base plate, a main light-condensing pattern formed on the base plate, and a sub light-condensing pattern formed on the main light-condensing pattern. The main light-condensing pattern includes a plurality of main prisms extended in a first direction. A cross section of a main prism taken along a second direction substantially perpendicular to the first direction has a substantially triangular shape. The sub light-condensing pattern includes a plurality of sub prisms formed on the main prisms and extended in a second direction substantially perpendicular to the first direction. A cross section of a sub prism taken along the first direction has a substantially triangular shape. Since light is condensed simultaneously in both a horizontal direction and a vertical direction through one light-condensing member, manufacturing costs and the thickness of backlight assembly are reduced.

  • Patent number: 7684393
    Abstract: Provided is a method for transmitting a burst in an optical burst switching system, in which when a burst is generated at an originating node, a burst control packet is transmitted to a destination node by way of a plurality of nodes and then a data burst is transmitted after a pre-allocated offset time. The method includes the steps of obtaining an arrival time of data bursts that survive competition to occupy an output channel among data bursts transmitted to the next node by way of the current node using offset time information in burst control packets for the survived data bursts, checking whether an empty void is present between the survived data bursts by using the obtained arrival time of the survived data bursts, and generating a new data burst originating from the current node, inserting the newly generated data burst into the checked empty void, and transmitting to the next node. This method can improve channel utilization and maximize performance of the optical burst switching system.

  • Patent number: 7636570
    Abstract: A method quickly resuming a downlink service in a hard handover in a cellular mobile communication system. To provide the fast downlink service to an MS during a hard handover from an OBS to an NBS, the NBS receives handover user information from the OBS, and generates an MS temporary ID using the handover user information to identify the MS. If user data is generated for the MS before a connection is established for traffic transmission between the MS and the NBS, the NBS transmits the user data to the MS on an HCCH using the MS temporary ID.
