Les,


> We are contemplating submitting a draft for this algorithm to the WG.


We would welcome that.  

Does your algorithm have any relationship to https://tools.ietf.org/html/draft-allan-lsr-flooding-algorithm-00? <https://tools.ietf.org/html/draft-allan-lsr-flooding-algorithm-00?>


> [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?


Not at this time.  As we said during our presentation, we found debugging this already ‘challenging’ and morphing it to be distributed and deterministic in distributed mode doesn’t pass our sense of a beneficial cost/benefit ratio.

We have no objections if others want to take this on.  Centralized mode Just Works.


> And the point of allowing multiple standardized algorithms to be defined was in the expectation that more than one might be proven useful.


Interoperability might also prove useful. :-)
