Abstract: 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.

Abstract: 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.
