摘要： A NAT entry management method and apparatus, 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 target static NAT entry includes a correspondence between the private address of the network device, a before-NAT source port number of the packet, an after-NAT source port number of the packet, and the address of the controller, and 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.

摘要： This application provides a communication method and apparatus. The method includes: A terminal device initiates a request to a first network element device in a public network core network to access a second network element device in a private network core network. If the private network core network and the public network core network are in a same trusted domain, the first network device sends first indication information to the second network element device, where the first indication information indicates the second network element device to skip performing an authentication operation on the terminal device. Compared with centralized authentication, embodiments of this application provide a new distributed authentication manner. Further, network devices in a same trusted domain may perform one authentication operation on a same accessing terminal device, to reduce signaling overheads.

摘要： The present invention provides an SDN network system, controller, and controlling method. The SDN network system includes: at least one N th level controller and at least two (N+1) th level controllers directly belonging to the N th level controller, where N is an integer greater than or equal to 1, where the (N+1) th level controller is configured to receive a first message sent by a node belonging to the (N+1) th level controller, and when it is determined that the first message is a cross-domain message according to status information of each node that is managed by the (N+1) th level controller and that belongs to the (N+1) th level controller, forward the first message to the N th level controller to which the (N+1) th level controller belongs; and the N th level controller is configured to receive the first message forwarded by the (N+1) th level controller belonging to the N th level controller, and perform decision processing according to status information of the (N+1) th level controller that is managed by the N th level controller and that belongs to the N th level controller and status information of boundary nodes of the (N+1) th level controller belonging to the N th level controller. A controller manages network information in a hierarchical manner, so that when any controller is attacked, networking information cannot be leaked, thereby improving security of the network information.

摘要： This application provides a session key generation method and apparatus. The method includes: A terminal device obtains a first public key of a radio access network device from a blockchain, where the first public key is signed by using an operator private key, and the first public key is generated based on a private key of the radio access network device. The terminal device processes the first public key by using an operator public key, to obtain a second public key of the radio access network device. The terminal device generates a first session key based on a first private key of the terminal device and the second public key. According to the foregoing technical solution, session key distribution is implemented in a decentralized or distributed architecture, and a man-in-the-middle attack risk is reduced.

摘要： This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities. This effectively avoids problems such as transmission congestion and a packet loss that are caused by an incapability of precisely identifying a service type and allocation of a same priority to service packets of different service types.

摘要： A power supply detection apparatus (300), a method, and a computer program product thereof are provided. The power supply detection apparatus (300) includes a PSE circuit (301), a power supply module (302), and a reverse circuit (303). The power supply module (302) is connected to the PSE circuit (301), and supplies power to the PSE circuit (301). The PSE circuit (301) is connected to the reverse circuit (303), and sends a first sounding electrical signal and a second sounding electrical signal. The reverse circuit (303) outputs the first sounding electrical signal to a wire pair group of an Ethernet cable, performs reverse processing on the second sounding electrical signal, and outputs the second sounding electrical signal to the wire pair group. The PSE circuit (301) is further configured to: determine, based on the first sounding electrical signal, a forward sounding result of a to-be-detected device connected to the Ethernet cable; and determine a reverse sounding result of the to-be-detected device based on the second sounding electrical signal. The power supply detection apparatus (300) is configured to determine that the to-be-detected device is a non-PD when the forward sounding result or the reverse sounding result is a short circuit.
