Abstract: A memory swapping method and apparatus are provided. The method includes: selecting n to-be-swapped-out pages; compressing the n to-be-swapped-out pages into n compressed blocks, and buffering the n compressed blocks in a compressed data buffer area; organizing at least one of the n compressed blocks into m to-be-written units; and writing the m to-be-written units into a swap area of a non-volatile storage device in a maximum of m batches, where at least one of the m to-be-written units is stored in a segment of continuous space in the swap area. The method reduces a quantity of write times during memory swapping, thereby prolonging a service life of the non-volatile storage device.

Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.

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.

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.
