Abstract: A method, an apparatus, and a system for measuring a network delay are disclosed. The method includes: acquiring delay measurement information obtained by measuring a service flow by at least one target logical port TLP, where the delay measurement information includes: timestamp information, a service flow identifier, and a TLP identifier; and transmitting the delay measurement information to a measurement control point MCP, so that the MCP determines details about a network delay according to the timestamp information, the service flow identifier, and the TLP identifier. Embodiments of the present application further provide an apparatus and a system for measuring a network delay. Embodiments of the present application achieve direct and accurate delay measurement of a service flow in scenarios of point to point transmission or point to multipoint transmission on the network, and reflect details about a real delay of the service flow.

Abstract: Data writing methods and computing devices are provided. An example data writing method is applied to a computer system, and the computer system includes a file system and a flash memory-based storage system. The example data writing method includes obtaining a target logical address, where the target logical address is an address allocated from a first logical block to target data to be written into the flash memory-based storage system, the first logical block is one of multiple logical blocks in the file system, and the flash memory-based storage system includes multiple physical blocks. It is determined that the target logical address belongs to the first logical block. The target data is written into a first physical block based on a correspondence between the first logical block and the first physical block, where the first physical block is one of the multiple physical blocks.

Abstract: Embodiments of this application provide an optical fiber ferrule, where n rows of optical fiber holes are symmetrically distributed on a mating end face of the ferrule, n>=3, and n is an odd number. Based on the layout design of optical fiber holes on the optical fiber ferrule, this application provides an optical fiber connector that includes a plurality of rows of optical fiber holes and that is compatible with one row and a relatively small number of rows of optical fiber holes, so that an optical fiber connector with a large number of cores can be forward compatible with an optical fiber connector with a small number of cores, thereby improving expandability and compatibility of the optical fiber ferrule.

Abstract: A system startup method includes creating a first thread when a kernel driver in a kernel mode detects a first disk partition, reading, in the kernel mode, metadata of the first disk partition using the first thread, and writing the metadata of the first disk partition into a first page cache using the first thread. In the kernel mode, metadata of a disk partition is pre-cached into a page cache using the first thread, and in a subsequent process in a user mode, the metadata of the disk partition is directly read from the page cache. A storage area of the page cache is memory and has a higher read/write operation rate compared with a disk.

Abstract: Provided are a method, apparatus and system for measuring network packet loss, the method includes: acquiring data packet measurement information measured by at least one target logical port to a traffic stream, transmitting the data packet measurement information to a measurement control point, so that the measurement control point determine the condition of network packet loss according to the data packet measurement information. As a data collecting point acquires the data packet measurement information measured by at least one target logical port to the traffic stream, and uniformly transmits the data packet measurement information to the measurement control point, when multiple target logical ports respectively perform measurement to acquire respective data packet measurement information, the measurement control point uniformly determines condition of packet loss of the traffic stream. Therefore, accurate packet loss measurement can be performed on the traffic stream under the scenario of point-to-point, point-to-multipoint or multipoint-to-multipoint networks.
