Abstract: A clock calibration method and apparatus is provided, where the method includes a terminal device uses first timing information, adjusts second timing information of the terminal device based on reference timing information, and when determining that a first condition is met, switches from using the first timing information to using the second timing information. The first timing information is primary timing information, the second timing information is standby timing information, and the first condition includes that: the first timing information is different from the reference timing information, and the second timing information is the same as the reference timing information; or the first timing information is different from the second timing information; or the first timing information is different from the reference timing information.

Abstract: A PCIe-based communications system includes a first processor and a plurality of switches, the plurality of switches include a first switch and a second switch, a first link exists between the first processor and the first switch, a second link exists between the first switch and the second switch, and a first standby link is configured between the first processor and the second switch. If the first link and the second link are not faulty, communicating, by the first processor, with the second switch through the first link and the second link; or if the first link or the second link is faulty, activating the first standby link, and communicating, by the first processor, with the second switch through the activated first standby link. Thereby stability of the communications system can be improved.

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.
