Abstract: A controller receives an access request message of a to-be-served flow that is sent by a network device. The access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device.

Abstract: An embodiment provides a packet transmission method and apparatus, to resolve a problem that occurs when a packet cannot traverse a NAT device when VTEPs communicate with each other through the NAT device. The method is applied to a VXLAN including a first VTEP, a second VTEP, and a NAT device. The method includes: performing, by the first VTEP, VXLAN encapsulation on a first packet, obtaining a second packet; sending, by the first VTEP, the second packet to the second VTEP through the NAT device; and performing, by the second VTEP, VXLAN decapsulation on the received second packet, to obtain the first packet. The first packet is a packet to be sent by the first VTEP, a destination port number of the second packet is obtained based on a destination IP address of the second packet, and a source port number of the second packet is a preset port number.

Abstract: A packet parsing method includes a source device receives a first ciphertext from a control device, where the first ciphertext is used to verify reliability of a packet from a parsing device, and the parsing device is a trusted device selected on a path between the source device and a destination device. The source device obtains a second packet including the first ciphertext according to the first ciphertext and a first packet, and sends the second packet to the destination device. The parsing device obtains, according to the second packet and a device identifier of the parsing device, a third packet including verification information and the first ciphertext. The destination device receives the third packet from the parsing device, and verify reliability of the third packet using the verification information and the first ciphertext included in the third packet.

Abstract: A method and an apparatus for implementing model training, and a computer storage medium are disclosed, and belong to the field of machine learning. When a machine learning model deteriorates, an analysis device first obtains validity information of a first feature set, where the first feature set includes a plurality of features used for training to obtain the machine learning model, the validity information includes a validity score of each feature in the first feature set, and a validity score of a feature is negatively related to correlation of the feature with another feature in the first feature set. Then an invalid feature in the first feature set is determined based on the validity information. A second feature set that does not include the invalid feature is finally generated, where the second feature set is used to retrain the machine learning model.
