Abstract: This application discloses a link fault handling method, a related apparatus, a storage medium, and a program product, and belongs to the field of communication technologies. In this method, a forwarding plane component of a network device updates a reference state table in time by actively polling a port status register, so that when forwarding a data flow, the forwarding plane component can sense a local faulty link in time based on the reference state table, and perform link switching in time, and a PHY chip does not need to report fault information to a control plane CPU in the network device, or wait for the control plane CPU to deliver an instruction. That is, this solution does not depend on control plane path computation, and does not require additional communication from a data plane to a control plane, to avoid a delay caused by fault handling of the CPU.

Abstract: This application discloses an information notification method and a related apparatus. The Ethernet storage system includes a first switching device and a first node, and the first switching device is an access device of the first node. The first node sends a join message to the first switching device. The join message includes an identifier of the first node and configuration information of the first node.

The join notification message includes the identifier of the first node and the configuration information of the first node.

Abstract: Smile treatment planning systems and methods are described herein. One method for adjusting an image of a smile may generally comprise receiving a three-dimensional (3D) digital model of a dental arch of a patient, receiving a digital facial image of the patient which includes an image of one or more teeth of the patient when smiling, registering the 3D digital model to the one or more teeth of the patient from the digital facial image, correcting the 3D digital model for scale and distortion to create a corrected 3D digital model, and overlaying the corrected 3D digital model onto the digital facial image.

Abstract: A packet sending method includes, after determining to send a packet based on a non-shortest path and determining that a second network device and a first network device on the non-shortest path belong to different groups, the first network device may send the packet to the second network device, and notify the second network device to send the packet based on a shortest path. After receiving the packet, the second network device may send the packet based on the shortest path, and notify another network device on the shortest path to send the packet based on the shortest path. In this way, in a process of sending the packet, after the packet passes through an inter-group path in the non-shortest path, a remaining path is the shortest path for sending the packet to a destination device.

Abstract: This application provides a packet processing method and a network device. A third network device is multi-homed to a first network device and a second network device, the first network device is configured with a first physical MAC address and a virtual MAC address, the second network device is configured with a second physical MAC address and the virtual MAC address, and the virtual MAC address is used to forward a user data packet to a network side. The method includes: a first network device receives a protocol packet from a third network device, where the protocol packet includes the second physical MAC address; and the first network device forwards the protocol packet to the second network device based on the second physical MAC address. Thus, the protocol packet can be normally forwarded without special configuration on a server, so that a cumbersome configuration process is avoided.

Abstract: A first network device receives a first data packet through an ingress port, and when a first forwarding path corresponding to the first data packet is faulty and there is no redundant path of the first forwarding path on the first network device, sends, through the ingress port of the first data packet, a first notification packet notifying that the first forwarding path is faulty. The first notification packet is generated by a data plane of the first network device, and the first notification packet is a data plane packet. Therefore, a network device that receives the first notification packet processes the first notification packet through a data plane. Then the network device can process a received data packet based on obtained fault information.

Abstract: A first communication apparatus obtains a sampling cycle. The sampling cycle is a time interval at which the first communication apparatus samples occupancy of a first buffer. The first buffer is used to store a data packet of a first priority. The first communication apparatus determines occupancy of the first buffer at a first sampling moment based on the sampling cycle. The first communication apparatus determines first duration based on the sampling cycle and the occupancy of the first buffer at the first sampling moment. The first duration is duration for which a second communication apparatus stops sending data to the first communication apparatus. The first communication apparatus sends first indication information to the second communication apparatus based on the first duration.
