Abstract: A Slow Protocol packet processing method includes receiving, by a network device, a first Slow Protocol packet, determining, based on port information of a port of the network device receiving the first Slow Protocol packet, that a negotiation process is already completed between the network device and the transmit end device, querying, based on device information of the transmit end device carried in the first Slow Protocol packet, whether a device information base stored by the network device in the negotiation process includes the device information of the transmit end device, and identifying the first Slow Protocol packet as a valid packet in response to a result that the device information base includes the device information of the transmit end device.

Abstract: This application provides a traffic forwarding method and a traffic forwarding apparatus. The method includes: determining, by a first network device, a first ARP entry of the access device, where the first ARP entry is used to indicate a mapping relationship among a MAC address, an IP address, and an egress port, the egress port includes a standby egress port, and the first network device is connected to the protection link through the standby egress port; receiving traffic sent by a network side; determining whether a fault exists in the first MC-LAG link; and when the first network device determines that a fault exists in the first MC-LAG link, sending the traffic to the second network device through the protection link based on a standby egress port number in the first ARP entry, where the standby egress port number is used to indicate the standby egress port.

Abstract: A method for implementing a software-defined network (SDN) includes receiving, by an SDN controller, virtual network information sent by a cloud computing platform, where the virtual network information includes a correspondence between information about a virtual machine (VM) and information about a server running the VM. The method also includes acquiring, by the SDN controller, physical network information, where the physical network information includes a correspondence between information about a top-of-rack (TOR) switch and the information about the server. Additionally, the method includes acquiring, by the SDN controller, a correspondence between the information about the VM and the information about the TOR switch according to the virtual network information and the physical network information.

Abstract: This application provides a VXLAN packet processing method, a device, and a system. After determining that a data packet sent by a CE device is a BUM packet, a PE device encapsulates the BUM packet to generate a VXLAN packet including an ESI label and a VXLAN packet including a BUM traffic label. The VXLAN packet including the ESI label is sent to an active-active gateway, so that the gateway can block forwarding of traffic to the CE device by using an interface configured with an ESI, to avoid a loop between the PE device and the CE device. The VXLAN packet including the BUM traffic label is sent to a remote PE, to block forwarding of the VXLAN packet to the CE device by using a secondary DF interface, thereby avoiding a multi-packet problem.
