A packet sending method includes, when a network element in a serial network receives a to-be-forwarded packet at a previous node from a previous network element, and when the network element needs to send a to-be-sent packet at a current node, determining whether the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, where the network element is an intermediate network element in the serial network; when the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, superimposing the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node, to obtain a to-be-forwarded packet at the current node; and sending the to-be-forwarded packet at the current node to a next network element of the network element.

Network structure and method for sending/receiving packet between network elements in network

A data transmission method and a device are provided. When determining that the first network element and the second network element is disconnected, the first network element stores identification information of the last frame of data and connection status information that are transmitted before the connection is disconnected. When determining a condition for re-communication is meet, the first network element generates a third key based on a first key and a second key, where the first key is a key used to transmit the last frame of data, and the second key includes a key used by the first network element and the second network element to transmit each of j frames of data before the last frame of data. The first network element communicates with the second network element based on the third key, identification information of an iframe of data, and the connection status information.

A method for selecting a management frame antenna based on a master-slave network and an apparatus are provided. In one example method, when a preset condition is met, a signal quality collection instruction is sent by a master device to a first slave device and a second slave device, so as to receive returned signal quality information. A management frame antenna is selected for the first slave device and a management frame antenna for the second slave device according to the received signal quality information, so that the selected management frame antennas can implement signal coverage optimization in an entire area managed by the master device.

Example sleeping and wake-up methods and apparatuses of a master-slave network, and a power saving system of a master-slave network, are described. One example method includes obtaining running statuses of slave devices on links from a link management list. A target device is determined. The target device is a slave device whose running status is idle. If running statuses of the target slave device to an end slave device on a link on which the target slave device is located are all idle, it is determined that a sublink from the target slave device to the end slave device on the link on which the target slave device is located is a target sublink. A power saving message is sent to at least one slave device on the target sublink, so that the slave device enters a sleep and listen state when receiving the power saving message.

Embodiments of the present disclosure disclose a data processing method, apparatus, and system. The method provided in the embodiments of the present disclosure includes receiving a data processing request sent by a client and obtaining a routing table according to the data processing request. The routing table stores structure information of a relational database. The relational database includes a plurality of sub-databases. The sub-database includes a plurality of partitioned tables, and the partitioned table includes a plurality of shards. The method also includes determining a target sub-database according to the data processing request and the routing table. The method further includes sending the data processing request to the target sub-database, so that the target sub-database performs an operation according to the data processing request.

The present invention provides an IP address allocation method for a master-slave network, an apparatus, and a system. A master device generates an IP address sub-segment group, and separately sends at least one IP address sub-segment in the IP address sub-segment group to at least one slave device, so that the slave device can use a received IP address sub-segment as a DHCP server address and allocate an IP address to a user device. In this way, the slave device can directly allocate the IP address to the user device, so that an IP address allocation time is reduced.

A handover method in a master-slave network, and a master device, and slave devices are provided. The method includes when a master device or a first slave device determines that a user device needs to be handed over to a second slave device, the first slave device sends, to the second slave device, a first identifier of a first network interface allocated by the first slave device to the user device, and first network connection information used after the user device establishes a connection to the first network interface of the first slave device. The first identifier of the first network interface and a second identifier of the user device correspond on a one-to-one basis. The first slave device deactivates the first network interface and the second slave device activates a second network interface.
