Abstract: An inter integrated circuit (I2C)-based communication method incudes when an I2C signal is encapsulated into a data packet for transparent transmission, an I2C status is indicated by a first field in a packet header of the data packet. The data packet may have no load part, or the data packet has a load part but the load part is used to carry a slave address, a read/write flag, or I2C data. Because the I2C status is indicated in the packet header of the data packet, the I2C status may be encapsulated in a same data packet together with the slave address, the read/write flag, or the I2C data. In other words, the I2C status may not need to occupy one data packet separately.

Abstract: This application discloses a peripheral component interconnect express (PCIe)-based data transmission method and apparatus. The method includes: A first node encapsulates data into a transaction layer packet (TLP) and then sends the TLP to a second node. The TLP includes a packet header and an extension header. The packet header includes a first field and a second field. The first field, the second field, and the extension header are used to indicate first encapsulation information. The first encapsulation information includes a data type of the data and at least one encapsulation parameter corresponding to the data type. In some embodiments, the first field, the second field, and the extension header are used to indicate the information required for transmitting the data.

Abstract: Embodiments of this application disclose a data processing method, which can be applied to a clock synchronization network system. The system can correct, based on a clock frequency error or a time error, a data timestamp of a data packet collected by the system in a time period in which there is no reference clock, so that a corrected system time of the data packet is consistent with a reference time. This improves accuracy of data record.

Abstract: A Peripheral Component Interconnect Express (PCIe)-based data transmission method includes a first node that encapsulates first data into a first transaction layer packet (TLP) and sends the first TLP to a second node, where a TLP header of the first TLP includes a first field, the first field is used to indicate a data type of the first data, and the data type includes at least one of the following: an image type, a video type, a control type, a security type, and a stream write (SWRITE) type. In embodiments of this application, the first field in the TLP header is used to indicate information required for data transmission, for example, the data type, so that nodes can communicate with each other without using a root complex.
