This application provides data transmission methods, devices, and systems. In one implementation, a method comprises: receiving, by a central device of a wireless network, at least one first data packet sent by a remote device of the wireless network, wherein each of the at least one first data packet comprises a sequence number indicating a relative location of a payload of the corresponding first data packet in a second data packet; reordering, by the central device, the at least one first data packet, based on the sequence number of each of the at least one first data packet, to obtain the second data packet; and sending, by the central device, the second data packet.

Data transmission method, device, and wireless network system

A network configuration method and apparatus are provided. The method includes: a first execution device sends to a management device, a device discovery message which is a layer 2 packet and includes a first port identifier, wherein a port identified by the first port identifier is a port, in an up state, of the first execution device. The first execution device receives from the management device a first configuration message which is a layer 2 packet and includes a configuration parameter which is for a second execution device and includes an internet protocol address of the second execution device that is connected to the port identified by the first port identifier. The first execution device sends the first configuration message through the port. According to the application, large amount of manpower is saved and network configuration efficiency is improved.

This application discloses a network topology discovery method and a node device. In this application, a root node device sends a link discovery message to a child node device through a first port; receives a link discovery acknowledge message sent by the child node device through a second port of the child node device, where the link discovery acknowledge message includes an identifier of the child node device and an identifier of the second port; and determines a first link based on the link discovery acknowledge message, where the first link is a link between the first port and the second port. According to the solutions of this application, when detecting that a link of a port is connected, the node device discovers an existing topology relationship through message interaction, so as to implement network topology discovery.

Embodiments of this application provide a data transmission method, a communications device, and a storage medium, to reduce pressure caused by a quantity of cross connections between intermediate nodes to the intermediate nodes in a network. In an embodiment of this application, a first communications device obtains Q first code block streams, and obtains a to-be-sent second code block stream based on the Q first code block streams. Q downlink ports are in a one-to-one correspondence with the Q first code block streams, the Q downlink ports correspond to S code block groups, one code block in the Q first code block streams corresponds to one code block group, and the second code block stream obtained by the first communications device includes L code block sets; and for each of the L code block sets, the code block set includes K code blocks corresponding to each of the S code block groups. In the solutions provided in this embodiment of this application, code block streams are multiplexed at a code block granularity, so that a quantity of cross connections between intermediate nodes in a network can be reduced, thereby reducing pressure on network management and operation and maintenance.

The present invention discloses a bandwidth adjustment method and a related device, so as to flexibly adjust a bandwidth. A controller obtains behavior characteristic statistics sent by an end cloud node device, and obtains bandwidth resources remaining on a system. The behavior characteristic statistics are a statistical result indicating behavior characteristics of occupying network bandwidth resources by a user when accessing the end cloud node device. The controller determines a bandwidth adjustment amount of the end cloud node device according to the behavior characteristic statistics and bandwidth remaining on the system. The controller sends a bandwidth adjustment instruction to a first network device. The bandwidth adjustment instruction is used to instruct the first network device to adjust, according to the bandwidth adjustment amount, a bandwidth allocated to the end cloud node device by a network device on a transmission link.
