Re: FW： New Version Notification for draft-liu-rtgwg-path-aware-remote-protection-00.txt

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
