Abstract: This application discloses a network slice information transmission method and apparatus. For example, a controller performs slice division on a network based on a service requirement and then obtains slice information, and sends the slice information to a first network device in the network by using a path computation element protocol (PCEP) packet, which includes first slice information corresponding to the first network device. After receiving the PCEP packet, the first network device parses the PCEP packet to obtain the first slice information, and further performs network slice configuration based on the first slice information. That is, in this application, the controller delivers the slice information by using the PCEP packet, so that after obtaining the PCEP packet, the first network device can obtain the first slice information corresponding to the first network device in a timely manner and perform network slice configuration without waiting for a configuration command.

Abstract: Embodiments of this application provide a data sending method, an apparatus, a device, and a readable storage medium. A server determines a first transmission point from a coordinated set, and determines a first downlink sending weight of the first transmission point. Then, the server determines a second downlink sending weight of a second transmission point based on the first downlink sending weight, and sends the second downlink sending weight to the second transmission point. When sending a data stream to an electronic device, the second transmission point determines a downlink sending weight corresponding to the data stream from a matrix, weights the data stream, and sends the weighted data stream to the electronic device.

Abstract: A database cluster architecture based on dual port solid state disk (SSD) is disclosed. The database cluster including a plurality of nodes and a plurality of dual port solid state disks (SSDs). Each dual port SSD of the plurality of dual port SSDs is connected to a unique pair of nodes and each node in the unique pair of nodes is connected to a unique pair of dual port SSDs. A first node of the plurality of nodes writes a transaction log to a first dual port SSD, a second node connected to the first dual port SSD acquires the transaction log from the first dual port SSD and operates a database process to recover data according to the transaction log when the first node crashes.

Abstract: The present disclosure provides a data management method for a database cluster including a first dual port SSD, a second dual port SSD, a first node, a second node, and a third node, where the first dual port SSD is connected to the first node and the second node, and the second dual port SSD is connected to the second node and the third node; and the first node writes a transaction log to the first dual port SSD, when the first node crashes, the second node acquires the transaction log from the first dual port SSD, and operates, according to the transaction log, data that is stored in the first node, so that, the second node or the third node can use a dual port SSD to read log information of the crashed node, and replace the first node to provide a service externally.
