Abstract: A data forwarding method and a related apparatus. The method includes: a head node obtains to-be-forwarded data; obtains a first segment identifier (SID) list corresponding to the to-be-forwarded data, where the first SID list is generated based on SIDs of a part of nodes in a target forwarding path; encapsulates, in front of the to-be-forwarded data, a packet header including the first SID list, to obtain a to-be-forwarded packet; and sends the to-be-forwarded packet based on the first SID list, where the target forwarding path includes M nodes, the first SID list is generated based on first N nodes in the M nodes, the first SID list is replaced with a second SID list at an intermediate node, and the second SID list is generated based on an Xth node to a Yth node in the M nodes.

Abstract: This application discloses a link fault handling method, a related apparatus, a storage medium, and a program product, and belongs to the field of communication technologies. In this method, a forwarding plane component of a network device updates a reference state table in time by actively polling a port status register, so that when forwarding a data flow, the forwarding plane component can sense a local faulty link in time based on the reference state table, and perform link switching in time, and a PHY chip does not need to report fault information to a control plane CPU in the network device, or wait for the control plane CPU to deliver an instruction. That is, this solution does not depend on control plane path computation, and does not require additional communication from a data plane to a control plane, to avoid a delay caused by fault handling of the CPU.

Abstract: Embodiments of this application disclose a packet processing method, apparatus, and device, and a packet forwarding method, apparatus, and device, to improve packet forwarding efficiency, save storage space of a network device, and expand a network scale. The packet processing method in the embodiments of this application includes: obtaining a packet including a destination address; obtaining outbound interface information of a network device on a forwarding path based on the destination address of the packet, where the forwarding path is a path for forwarding the packet from a source device to a destination device corresponding to the destination address; and encapsulating a packet header for the packet, where the packet header includes the outbound interface information of the network device that forwards the packet on the forwarding path.
