Abstract: A data flow redirection method to overcome a disadvantage that a quantity of adjustable data flows is relatively small due to limited space of a flow specification forwarding table. The method includes receiving, by a network device, a control message sent by a control device, where the control message carries redirection routing information of a data flow and a redirection routing indication, the redirection routing indication instructing to convert the redirection routing information of the data flow into a forwarding entry in a target forwarding table, and tablespace of the target forwarding table is greater than tablespace of a flow specification forwarding table of the network device, and converting, by the network device, the redirection routing information of the data flow into the forwarding entry in the target forwarding table according to the redirection routing indication.

Abstract: A method, includes receiving a packet flow optimization policy including a flow identifier of a target packet flow, a device identifier of a to-be-adjusted forwarding device, and information about the next hop; obtaining status information of an access control list (ACL) of the to-be-adjusted forwarding device based on the device identifier, where the status information includes resource usage status information of the ACL and capability information that indicates whether the to-be-adjusted forwarding device supports packet flow forwarding that is based on the ACL; and when determining, based on the status information, that the ACL includes an idle resource and the to-be-adjusted forwarding device supports packet flow forwarding that is based on the ACL, sending an ACL record to the to-be-adjusted forwarding device, where the ACL record includes the flow identifier and the information about the next hop.
