Abstract
A controller obtains a forwarding latency requirement of a service flow and a destination address of the service flow, and determines a forwarding path that meets the forwarding latency requirement. The controller determines that an ingress node forwards a first cycle time number of a packet and an intermediate node forwards a second cycle time number of the packet, and separately determines a corresponding adjacent segment identifier. A label stack generated by the controller includes the adjacent segment identifier and the adjacent segment identifier. The controller sends the label stack to the ingress node, to trigger the ingress node to forward the packet within a period of time corresponding to the first cycle time number. The controller determines the forwarding path based on the forwarding latency requirement of the service flow, and generates a label stack corresponding to a forwarding time point.
