Abstract: This application provides a communication method, apparatus, and device. In the method, when a target tenant has a network operation and maintenance management requirement for accessing first information by using a first service, an NMS of the target tenant can successfully access the first information regardless of whether the target tenant has permission to invoke the first service. In addition, the first information is transmitted between an EMS and the tenant NMS of the target tenant without passing through an operator NMS. Therefore, security of the first information can be ensured.

Abstract: In a policy conflict management method, a first controller receives first policy information that comprises a first policy configured by a core network for UE. The first controller detects that a policy conflict occurs between the first policy information and second policy information, where the second policy information includes a second policy configured by a second controller for the UE, or a first decision result obtained after the first controller makes a policy decision according to the second policy. The first controller makes a policy decision according to the first policy and the second policy to obtain a second decision result. The first controller then sends the second decision result to a radio access network RAN network element for execution.

Abstract: A model distillation training method provides for establishment of a distillation training communication connection with a second device prior to performing distillation training on a neural network model. Based on exchange of distillation training information between the first device and the second device, the second device configures a first reference neural network model by using first configuration information sent by the first device. After configuring the first reference neural network model, the second device performs operation processing on first sample data in first data information based on the configured first reference neural network model by using the first data information to obtain first indication information, and sends the first indication information to the first device. The first device trains, by using the first indication information, a first neural network model designed by the first device.

Abstract: A federated learning method, apparatus, and system are disclosed. A first node obtains data distribution information of a plurality of second nodes based on a target data feature required by a training task; the first node selects at least two target second nodes from the plurality of second nodes based on a target data class required by the training task and the data distribution information of the plurality of second nodes; and the first node indicates the at least two target second nodes to perform federated learning, to obtain a federated learning model that is in the training task and that corresponds to the target data class. In this way, when participants have a plurality of data distributions, a trained model is prevented, as much as possible, from being affected by data poisoning.

Abstract: A buffer control method, a network element, and a system. The method includes: receiving, by a network element, a flow table message from a controller, where the flow table message includes buffer information of a data packet matching a flow table; processing, by the network element, a buffer of the data packet based on the buffer information, and sending a flow table response message to the controller. In the method, the network element can save, based on a corresponding saving manner, at least one data packet matching the flow table to the buffer corresponding to the flow table. Thus a data flow granularity-based buffer processing manner can be supported in an OpenFlow protocol, and a data buffering requirement of a mobile network can be met.

Abstract: Embodiments provide an aggregate rate control method, a device, and a system. A gateway switch receives a flow entry and a link table from a software-defined networking (SDN) controller. The flow entry includes at least a match field and a flow-entry instruction, and the link table includes at least a packet processing operation. The gateway switch parses to obtain header information of a received target data packet, and matches the header information with the match field in the flow entry. When the header information matches the match field in the flow entry, a link instruction is executed in the flow-entry instruction in the flow entry. The packet processing operation in the link table is performed, and the packet processing operation is used to discard or buffer the target data packet when a bit rate of an aggregate service flow is greater than a specified maximum aggregate rate.
