    Abstract: A packet forwarding method, apparatus, and system in which a host receives a first packet sent by a gateway, and parses the first packet to obtain a source IP address and a source MAC address from the first packet; queries a host cache table, when a mapping relationship between the source IP address and the source MAC address does not exist in the host cache table, saves the mapping relationship between the source IP address and the source MAC address in the host cache table; the host generates a response packet according to the first packet, and queries the host cache table to acquire a first destination MAC address corresponding to a first destination IP address that is in the response packet; and forwards, according to the first destination MAC address, the response packet to an external network by using the gateway.

    Abstract: A method for synchronizing virtual machine location information between data center gateways, a gateway, and a system, where a second gateway of a second data center receives a first location update message from a first gateway of a first data center, where the first location update message notifies that location information of the first virtual machine is changed. The second gateway deletes, according to the first location update message, a media access control (MAC) route of the first virtual machine saved in the second gateway, and the second gateway learns, from the first virtual machine to obtain current location information of the first virtual machine when the second gateway receives a packet destined for the first virtual machine and the second gateway does not save the MAC route of the first virtual machine.

    Abstract: Embodiments of the present disclosure disclose a BUM traffic control method, a related apparatus, and a system. A traffic controller receives, through a tunnel, a BUM packet encapsulated by a network device in a target broadcast domain. The traffic controller collects, based on the received BUM packet, statistics about a BUM traffic value of a target object within a preset time period, and determines whether the BUM traffic value is greater than a preset BUM traffic threshold of the target object. If the BUM traffic value is greater than the preset BUM traffic threshold, the traffic controller controls BUM traffic of the target object, to reduce the BUM traffic of the target object. The foregoing solution can resolve a problem of BUM packet flooding caused by an increase in a quantity of hosts or an increase in a quantity of network devices in a communications network.
