Hi Yisong,
I have reviewed the draft and have two questions:
1. Which scenarios can benefit from rapid fault perception and
switchover？
2. How is remote fault perception technology implemented, and what
requirements does it pose on upper-layer protocols and hardware?
Best Regards,
Tingting Han

Hi Everyone,
We have just submitted a draft on the rapid switchover of remote fault
perception. The link for this draft is:
https://datatracker.ietf.org/doc/draft-liu-rtgwg-path-aware-remote-protection/The
current main protection technologies include local protection through FRR,
such as TI-LFA protection, and end-to-end protection through multi-path
protection.In specific network scenarios, such as a spine-leaf two-layer
architecture, TI-LFA cannot be deployed, and even if it is deployed, traffic
will still loop during a fault. Therefore, this draft proposes a mechanism for
rapid switchover that is aware of remote paths. By associating the next hops
with remote path information at the forwarding plane, the local end can be
quickly notified to switch in the event of remote fault, achieving fault
switchover in milliseconds, or even microseconds.We welcome your feedback. If
you have any questions or comments, please feel free to let us know.
Best Regards
Yisong
