Title:
DATA TRANSMISSION METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/022263
Kind Code:
A1
Abstract:
Provided are a data transmission method, a communication apparatus, a network device, a communication system, a storage medium and a computer program product, which solve the current problem of bandwidth waste being severe when service carrying is performed on the basis of FlexE technology. In the present application, the frame structure of a small-particle service frame is newly defined, such that an Ethernet (ETH) interface can be used for transmitting service data in a time-division multiplexing manner. Therefore, even ordinary Ethernet interfaces that do not support a standard FlexE mode can also effectively utilize the bandwidth of the Ethernet interface, so as to realize bandwidth isolation. By means of the technical solution of the present application, the utilization rate of channel bandwidths can be greatly improved, and especially when a low-rate service is carried, the utilization rate of channel bandwidths can be significantly improved, thereby preventing bandwidth waste.
