TRANSMISSION PATH FAULT PROCESSING METHOD AND APPARATUS, AND SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18536967 titled 'TRANSMISSION PATH FAULT PROCESSING METHOD AND APPARATUS, AND SYSTEM

Simplified Explanation

The patent application describes a method and apparatus for processing transmission path faults in a network system. Here are the key points of the innovation:

  • Receiving a stitching label and a stitching label stack list from a stitching network device.
  • Identifying a faulty stitching network device in the path of a packet being sent through a primary path.
  • Replacing the stitching label in the label stack list with the stitching label stack list.
  • Switching the packet to a backup path based on the updated label stack list.

Original Abstract Submitted

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.
