Abstract: A method and apparatus for transmitting a service flow based on a flexible Ethernet, where a bandwidth resource corresponding to a bundling group (BG) of a flexible Ethernet is divided into M timeslots, service data of a service flow is encapsulated in N timeslots in the M timeslots, and the method includes: when a first PHY in the BG fails, determining, based on a preconfigured first timeslot configuration table (TCT), a target timeslot (TTS) in the N timeslots that is mapped to the first PHY; searching the M timeslots for an idle timeslot (ITS) based on the first TCT; adjusting the first TCT when a quantity of ITSs is greater than or equal to a quantity of TTSs, so that all the N timeslots are mapped to PHYs other than the first PHY; and transmitting the service flow by using the mapped PHYs of the bundling group.

Abstract: A computer device and a method for reading or writing data by a computer device are provided. In the computer device, a central processing unit (CPU) is connected to a cloud controller using a double data rate (DDR) interface. Because the DDR interface has a high data transmission rate, interruption of CPU can be avoided. In addition, the CPU converts a read or write operation request into a control command and writes the control command into a transmission queue in the cloud controller. Because the cloud controller performs a read operation or a write operation on a network device according to operation information in the control command, after writing the control command into the transmission queue, the CPU does not need to wait for an operation performed by the cloud controller and can continue to perform other processes.
