Embodiments of this application disclose a method for communication in a data center, an apparatus, and a system. The data center includes a plurality of servers, a plurality of electrical switches, and at least one optical cross-connect device, and uplink ports of at least two of the plurality of electrical switches are interconnected to the at least one optical cross-connect device. The method includes: receiving network topology information delivered by a topology manager; obtaining a data flow; and configuring a routing policy for the data flow based on the network topology information, where the routing policy includes any one or a combination of the following routing policies: a first routing policy, where the first routing policy indicates to forward the data flow through an optical channel in the at least one optical cross-connect device; a second routing policy, where the second routing policy indicates to split the data flow into at least two sub-data flows for forwarding; and a third routing policy, where the third routing policy indicates to forward the data flow through the electrical switch in the data center.
