Abstract
A packet sending method, a network node, and a system, where a controller obtains a forwarding latency requirement of a service flow and a destination address of the service flow, determines a forwarding path that meets the forwarding latency requirement, and determines a number of a first cycle time in which an ingress node forwards a packet and a number of a second cycle time in which an intermediate node forwards the packet. The controller sends a first entry to the ingress node. The first entry includes a sequence number of the packet and the first cycle time number. The controller sends a second entry to the intermediate node. The second entry includes the sequence number of the packet and the second cycle time number.
