    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 node isolation method, a switching device, and an Ethernet storage system implement node isolation between zones in the Ethernet storage system. A first switching device in the Ethernet storage system determines a first access control list ACL rule between a first node and a second node, where the first switching device is an access device of the first node, the first node and the second node are located in the Ethernet storage system, and the first node and the second node correspond to a first zone; and if a packet whose source is the first node or a packet whose destination is the first node matches the first ACL rule, forwards the packet.

    Abstract: A method and an apparatus for topology discovery are disclosed. Link state information of each port of each device on a ring network is confirmed through neighbor negotiation between a first device and a neighbor device, and by broadcasting a link state information base of each device to other devices on the ring network, each device on the ring network can obtain the newest and synchronous link state information of each port on the ring network, so that each network device on the ring network implements topology discovery of the ring network where the network device is located.

    Abstract: This application discloses a queue control method and apparatus. The queue control method includes: A first device obtains a packet drop parameter of a first queue, where the packet drop parameter of the first queue is determined based on a packet that is dropped because the packet cannot be added to the first queue; and when the packet drop parameter of the first queue is greater than a first packet drop threshold, the first device increases a first cache parameter, where the first cache parameter is for adjusting a queue threshold of the first queue, and the queue threshold of the first queue indicates a maximum total quantity of bytes of packets that are allowed to be cached in the first queue.

    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.

    Abstract: A first network device in a first device group receives a first packet that is sent by a first terminal device connected to the first network device and whose destination address is an IP address of a second terminal device connected to a second network device in a second device group. When a first inter-group interconnection link exists between the first network device and the second device group, and congestion does not occur on the first inter-group interconnection link, the first network device sends the first packet to the second network device through the first inter-group interconnection link.
