  • Patent number: 8175456
    Abstract: Provided is a burst scheduling method in an Optical Burst Switching (OBS) system in which a plurality of nodes are connected through a mesh-type network. When a TDB which has used many network resources via a plurality of nodes and an SHG burst generated in a previous node, among bursts including BCPs transmitted from the previous node, compete in a current node so as to occupy a specific output channel, scheduling is performed to cause the TDB to have a higher priority than the SHG burst such that the corresponding output channel is occupied. Therefore, it is possible to minimize a burst loss in a network node, thereby enhancing the overall system performance.

  • Patent number: 8173034
    Abstract: Some embodiments include methods of utilizing block copolymer to form patterns between weirs. The methods may utilize liners along surfaces of the weirs to compensate for partial-width segments of the patterns in regions adjacent the weirs. Some embodiments include methods in which spaced apart structures are formed over a substrate, and outer surfaces of the structures are coated with a thickness of coating. Diblock copolymer is used to form a pattern across spaces between the structures. The diblock copolymer includes a pair of block constituents that have different affinities for the coating relative to one another. The pattern includes alternating segments, with the segments adjacent to the coating being shorter than the segments that are not adjacent to the coating.

  • Patent number: 8156392
    Abstract: An apparatus, system, and method are disclosed for bad block remapping. A bad block identifier module identifies one or more data blocks on a solid-state storage element as bad blocks. A log update module writes at least a location of each bad block identified by the bad block identifier module into each of two or more redundant bad block logs. A bad block mapping module accesses at least one bad block log during a start-up operation to create in memory a bad block map. The bad block map includes a mapping between the bad block locations in the bad block log and a corresponding location of a replacement block for each bad block location. Data is stored in each replacement block instead of the corresponding bad block. The bad block mapping module creates the bad block map using one of a replacement block location and a bad block mapping algorithm.
