Abstract: Embodiments of this application relate to the field of communications technologies, and disclose a dynamic scheduling method, an apparatus, and a system, so as to reduce information exchange costs and calculation complexity of data scheduling and route allocation. The method includes: receiving, by a scheduling platform, first VOQ length information of each aggregation switch in each timeslot; aggregating all the received first VOQ length information, to obtain global VOQ length information, where the global VOQ length information includes a total quantity of data packets that need to be sent from each of M pods to other pods than the pod; determining a transmission matching scheme based on the global VOQ length information; and sending corresponding matching result information to each aggregation switch according to the transmission matching scheme, so that each aggregation switch sends a data packet according to the transmission matching scheme.

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.
