  • Patent number: 12135661
    Abstract: Example computer-implemented methods, media, and systems for processing input/output (I/O) commands using block size aware polling are disclosed. One example method includes creating multiple polling queues and multiple interrupt queues in a transport drivers layer of a storage stack. A first I/O command is received from a core layer of the storage stack and by the transport drivers layer. A ratio of a total number of multiple small block size commands in the transport drivers layer to a total number of multiple outstanding I/O commands in the transport drivers layer is determined to be larger than a predetermined first threshold. In response to determining that the ratio is larger than the predetermined first threshold, the polling mode is applied to the first I/O command through the submission of the first I/O command to a first polling queue in the multiple polling queues.

  • Patent number: 12111491
    Abstract: A single-core polarization-maintaining dispersion compensation micro-structured optical fiber comprises a fiber core, a first layer of air holes surrounding the fiber core, the cladding defects on the x-axis, the cladding defects on the y-axis, and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice. Three consecutive air holes are omitted to form a solid area. This solid area is the fiber core. There are two cladding defects along the x-axis. Their centers are respectively located at the two vertices of the hexagon on the x-axis, which is formed by the fourth air hole ring from the core exclusive the central air hole. Each cladding defect along the x-axis contains 7 air holes and goes through from the core by only 1 layer of air holes. There are also two cladding defects along the y-axis.
