Abstract: This application discloses a transmission path fault processing method and apparatus, and a system, to resolve a problem that a packet fails to be forwarded because a previous-hop node of a faulty node cannot process a stitching label. The method includes: receiving, by a first network device, a stitching label and a stitching label stack list corresponding to the stitching label that are sent by a stitching network device; determining, in a process of sending a packet through a primary path, that the stitching network device is faulty, where the packet includes a label stack list, and the stitching network device is a next-hop network device of the first network device; and replacing, by the first network device, the stitching label in the label stack list with the stitching label stack list, and switching, based on the updated label stack list, the packet to a backup path for sending.

Abstract: A method for forwarding a packet in a network. The network includes a first network node, a second network node, and a third network node. The method is applied to the first network node, and the method includes: generating a correspondence between a first segment identifier (SID) and a second SID, where the first SID is an identifier that corresponds to the private network, and the second SID is an SID of the third network node; receiving a first packet whose destination address is the first SID; and when it is determined that the second network node is unreachable, pushing the second SID into the first packet to generate a packet, and sending the packet to the third network node.

Abstract: Embodiments of this application provide a network optimization method, a network optimization system, and a network device, and relate to the communications field. A first network device adjusts, if it is detected that a communications link between the first network device and a second network device is in an abnormal state, a metric of at least one data flow received by the first network device; and the first network device selects a transmission path for the at least one data flow based on adjusted metric, and transmits the at least one data flow to the selected transmission path. In this way, load of the communications link is reduced, and the communications link is restored to a normal state.
