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: A route determining method and apparatus, and a communications device are provided. The method includes: obtaining startpoint information and endpoint information of a required path, where the startpoint information includes a sequence number of a startpoint POD and a sequence number of a startpoint edge switch, and the endpoint information includes a sequence number of an endpoint POD and a sequence number of an endpoint edge switch; determining, from an n-dimensional Latin square, an element whose row is the sequence number of the startpoint edge switch and column is the sequence number of the endpoint edge switch; and if the sequence number of the startpoint POD is the same as the sequence number of the endpoint POD, determining that the required path is the startpoint edge switch, an aggregation switch corresponding to the element in the POD, and the endpoint edge switch.
