Abstract: A data transmission method, and a related apparatus, are provided. The method include: determining, by a first controller in available transit switches in a data center network, available transit switches respectively transiting m groups of data, where one available transit switch is configured to transit at least one group of the data, and a difference between quantities of groups of the data transited by any two available transit switches does not exceed a second threshold; and instructing, by the first controller, a destination network node to send routing information to the source network node, where the routing information includes an identifier of an available transit switch configured to transit a data group transmitted by the source network node to the destination network node. The foregoing solution can balance load of each transit switch in the data center network, improve a bandwidth resource utilization rate, and reduce a transmission delay.

Abstract: The present invention provides a wireless local area network WLAN and a method for communicating by using the WLAN, which includes at least one radio module and an access controller. The radio module converts a first air interface wireless signal from a station into a first baseband signal, and bears the first baseband signal on an Ethernet and sends the first baseband signal to the access controller. The access controller processes the first baseband signal to generate first service data, and forwards the first service data. The access controller further receives second service data, processes the second service data to generate a second baseband signal, and bears the second baseband signal on the Ethernet and sends the second baseband signal to the at least one radio module. The present invention can increase the efficiency and utilization rate of a spectrum.
