Patent attributes
Techniques are described for providing node protection in a Source Packet Routing in Networking (SPRING) network. In some examples, a first network device, responsive to detecting a configuration request to provide node protection to a second network device that is adjacent to the first network device: generate at least one context table; configure at least one forwarding entry that indicates: a primary path between the first network device and a third network device, and a backup path, based at least in part on the at least one context table, between the first network device and the third network device that bypasses the second network device; while the second network device has not failed, forward network packets to the third network device using the primary path; and responsive to determining that the second network device has failed, forward network packets to the third network device using the backup path.
