    摘要： Embodiments of the present invention provide a method and an apparatus for compressing a label stack. The method includes: obtaining, by a network device, 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, by the network device, 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, by the network device, 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, by the network device, a source node on the forwarding path to perform packet processing according to the second label stack. In this way, when a forwarding node forwards a packet, a length of a label stack pushed into the packet can be shortened, thereby reducing a total length of the packet, which is conducive to transmitting the packet in a network. Correspondingly, the embodiments of the present invention further provide a method and an apparatus for decompressing a label stack.
