  • Publication number: 20190097967
    Abstract: A NAT entry management method and a NAT device are disclosed. The method includes: receiving and storing, by a NAT device, a connection parameter, where the connection parameter includes an address of a controller; receiving a packet sent by a network device, where a source address of the packet is a private address of the network device and a destination address of the packet is the address of the controller; performing NAT on the packet, where an after-NAT source address of the packet is a public address; and when a static entry condition is met, generating a target static NAT entry, where the static entry condition includes that the destination address of the packet is the address of the controller. This can prevent aging of the NAT entry from affecting communication between the network device and the controller.

  • Publication number: 20190014139
    Abstract: The present disclosure relates to a data flow forwarding abnormality detection method. In one example method, a switching device through which a to-be-detected data flow passes is determined by a controller. At least one flow entry in the switching device that matches the to-be-detected data flow is obtained. The at least one flow entry comprises actual traffic and a match field. The actual traffic is a value of a counter corresponding to the match field. An overdetermined equation set is established based on the actual traffic and theoretical traffic of a data flow in the switching device that matches the match field. Based on the overdetermined equation set, a determination is made on whether the at least one flow entry is abnormal.
