Abstract: This application provides a message parsing method, a data transmit end, a data receive end, and a system, and pertains to the field of network technologies. The method includes: when creating an XML message, the data transmit end may add a target identifier to the XML message to indicate an independent message block in the XML message, where the independent message block is an independent context-free message block, and then may transmit the XML message to the data receive end; and in a process of receiving the XML message, if it is detected that the target identifier exists in the XML message, the data receive end may capture, from the XML message, the independent message block corresponding to the target identifier, and then parse the captured independent message block.

Abstract: Embodiments of the present invention provide a channel coding method for a data exchange service, and a device. The method includes: coding source data to generate a first bitstream, where a code rate of a data part of the source data is p, and p is less than ⅓; puncturing the first bitstream to generate a second bitstream; mapping, in an interleaved manner, the second bitstream to q bursts to generate q burst sequences, for modulation, where the second bitstream fully occupies each burst sequence of the q burst sequences, and q is an integer greater than 4; and sending the q modulated burst sequences to a receive end. In the embodiments of the present invention, a code rate of channel coding for a data exchange service is reduced, so that reliability of terminal data transmission can be improved at same power consumption or less power consumption.

Abstract: In a data storage method, a storage system comprises first and second medium layers for data storage, wherein the performance of the first medium layer is different from the performance of the second medium layer. Based on the performance difference between the two layers, the storage system stores data in the first medium layer and the second medium layer based on different erasure code ratios. The different erasure code ratios correspond to different write amplification, and result in different storage space utilization.
