    Abstract: A power over Ethernet method where power sourcing equipment (PSE) detects and determines that a first set of cable pairs and a second set of cable pairs of an Ethernet twisted pair are connected to a valid powered device (PD), the PSE receives a link layer discovery protocol data unit (LLDPDU) from the PD, where the LLDPDU includes a load quantity type-length-value (TLV) used to notify a quantity of PD loads included in the PD, and when the PD receives power from both the first set of cable pairs and the second set of cable pairs, and the PD includes two PD interfaces, and the PD includes two PD loads, the PSE supplies power to the PD at a first power using the first set of cable pairs, and supplies power to the PD at a second power using the second set of cable pairs.

    Abstract: This application provides a method for secure multi-terminal cooperative working, applied to a network on which a plurality of terminal devices perform cooperative playing and/or cooperative recording, where the plurality of terminal devices include a first terminal device. The method includes: determining, by the first terminal device, a security mechanism; obtaining, by the first terminal device, cooperative working information, where the cooperative working information is information played and/or recorded by the plurality of terminal devices; and performing, by the first terminal device, security processing on the cooperative working information based on the security mechanism. After obtaining the cooperative working information, the first terminal device performs security processing on the cooperative working information based on the security mechanism, so that a process other than the cooperative working process cannot access the cooperative working information, thereby ensuring security of the cooperative working information.

    CPC classification number: G06F11/2094

    Abstract: A system includes a processor and a memory. The processor locates a first memory chip that is faulty in a memory. After the first memory chip is isolated or replaced, the processor may reset the first memory chip when other memory chips in the memory are maintained to work normally. When a fault occurs in a memory chip in the memory, after the first memory chip that is faulty is isolated or replaced, the processor may independently reset the first memory chip without affecting the other memory chips in the memory. Resetting the first memory chip enables the first memory chip to restore to normal. A memory chip that can be normally used is used as a redundant memory chip or may continue to be used.
