In an embodiment an over the air (OTA )system software upgrade control method includes accessing, by a terminal device, an OTA server, and obtaining version information of a target system software upgrade package that is on the OTA server and whose version is later than a current system software version of the terminal device, requesting, by the terminal device, from a management device, authorization information corresponding to the version information of the target system software upgrade package, determining, by the terminal device in response to the authorization information that is received from the management device and that corresponds to the version information of the target system software upgrade package, that the target system software upgrade package is obtainable from the OTA server, and obtaining the target system software upgrade package from the OTA server, wherein the authorization information indicates whether the terminal device is allowed to obtain the target system software upgrade package from the OTA server.

A network management apparatus according to an embodiment includes: a storage device configured to store information indicating a correspondence relationship between information objects related to a logical layer, information objects related to a physical layer in a network configuration, and information objects related to a facility layer which are objects in which the information objects related to the physical layer are housed; an acquisition unit configured to acquire an information object related to an occurrence path of a failure in the logical layer of the network configuration, from the storage device; and a search unit configured to search for, among the information objects related to the facility layer stored in the storage device, an information object related to the facility layer and the physical layer associated with the information object related to the occurrence path of the failure acquired from the acquisition unit, as a candidate for a facility that causes the failure.

A network attack detection method and apparatus is provided. The network protection device obtains first key data from received first network traffic, and matches the first key data with an attack signature in a signature database to obtain a first matching result; if the network protection device determines, based on the first matching result, that the first network traffic is aggressive, the network protection device obtains a target attack detection model based on the first network traffic, where the target attack detection model is used to identify one or more attack signatures that are different from the attack signature in the signature database; and when the network protection device receives second network traffic, the network protection device determines, based on the target attack detection model, whether the second network traffic is aggressive.

The present disclosure provides a receiver circuit and a receiver circuit control method. In the present disclosure, the input data is detected by a detection circuit to obtain a data rate detection result, and the bandwidth of the receiver is automatically adjusted according to the data rate detection result.
