Thank you. Please look at the feature description and it does seem to be exactly the same as this draft. Please confirm. It would appear to be a different, proprietary, and unpublished algorithm. [Les:] Yes, this is a different algorithm than either https://datatracker.ietf.org/doc/draft-chen-lsr-dynamic-flooding-algorithm/ or https://datatracker.ietf.org/doc/draft-cc-lsr-flooding-reduction/ We are contemplating submitting a draft for this algorithm to the WG. This will give us three different implementations, using three different algorithms, none of which will inter-operate. Whee!!! :-( [Les:] As I understand it, draft-chen only supports centralized mode - which is why it is Informational track and does not have interoperability concerns. Sarah/Tony - do you have plans to extend this to support distributed mode and then standardize it? At present there are no standard algorithm candidates which have achieved WG status - though that likely will change very soon. And the point of allowing multiple standardized algorithms to be defined was in the expectation that more than one might be proven useful. There maybe other vendors due to industry demand have to get the feature deployed before it reaches standards vendor consensus with the IETF. Our implementation shipped last year. [Les:] As did Cisco's. We are testing this feature and planning to deploy but wanted to ensure that this is the same as the draft on the standards track. It does not appear to be, but someone from Cisco should confirm. [Les:] Confirmed. Les Tony
