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.

Abstract: Embodiments of the present application provide a method and an apparatus for compressing a label stack. The method includes: obtaining a first label stack corresponding to a forwarding path, where the first label stack comprises node labels corresponding to each node on the forwarding path; selecting a first node label from the first label stack, where when forwarding a packet, a node corresponding to the first node label is capable of encapsulating at least two layers of labels in the packet; replacing at least two adjacent labels located after the first node label in the first label stack with a first compression label, to generate a second label stack; and instructing a source node on the forwarding path to perform packet processing according to the second label stack. In this way, a length of a label stack pushed into the packet can be shortened.
