摘要： 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.

摘要： A network-on-chip flit transmission method and a network-on-chip flit transmission apparatus. The method includes: receiving a current flit including an operation ID Op ID, an operation type Op Type, and a payload; when determining that acceleration processing needs to be performed on the current flit, determining, according to the Op Type, whether the payload of the current flit affects an execution result of a destination node of the current flit, where the execution result is a result obtained by executing, by the destination node, a task corresponding to the Op ID; and forwarding the current flit to a next node if a determining result is yes; and discarding the current flit if a determining result is no. Therefore, not only a quantity of flits that need to be transmitted on a network-on-chip can be greatly reduced, but also a calculation amount of the destination node can be reduced.

摘要： Embodiments include a front-end device collaboration method, applied to a security and protection system to reduce a delay of a collaborative operation. The security and protection system includes a plurality of front-end devices, and the plurality of front-end devices include a first front-end device and a second front-end device. The method includes: the first front-end device determines that a preset collaboration trigger event exists; and the first front-end device sends a collaboration instruction to the second front-end device, where the collaboration instruction is used to instruct the second front-end device to perform an operation corresponding to the collaboration instruction.

摘要： A packet transmission method and device are disclosed. A first pseudo wire (PW) is established between a first node and a second node. The first node obtains a first service packet, and performs SRv6 encapsulation on the first service packet to obtain a second service packet. The second service packet includes the first service packet and information about the first PW. The first node sends the second service packet to the second node through the first PW. After receiving the second service packet, the second node performs SRv6 decapsulation on the second service packet to obtain the first service packet. An ingress PE device can perform SRv6 encapsulation on a PW service, and encapsulate PW description information and a to-be-transmitted service packet into an actually sent service packet, and an egress PE device performs SRv6 decapsulation on the service packet received through the PW to obtain the to-be-transmitted service packet.
