With all respect, there are other distributed solutions on the table…

Thanks.

We do not need to standardize the centralized algorithm. - A small change to this work allowed for distributed algorithms and for outside work on distributed algorithms to continue in parallel. - We have another original work that started primarily as a distributed algorithm (draft-cc-ospf-flooding-reduction) - Finally we also have: - Cross-pollination of ideas. - Failed attempts at merging. - An authors list "Arms-Race". Moving forward: - During IETF 103 I proposed we have no conflict if we: 1) adopt draft-li-lsr-dyanmic-flooding as the base WG document.. 2) have authors of draft-cc-lsr-flooding-reduction work on a distributed algorithm as they started with. - Acee agreed during the meeting (as chair) that this was the best way forward. We had some agreement form the floor as well. - Any good ideas regarding the distribution of a centralized topology can be debated and added (with appropriate attribution) to the base document after we adopt one. - This is what happens when we adopt a document as WG work, we work on it. - The original authors of the distributed solution can continue to work on their distributed algorithm in a separate document which would also need standardization. Does anyone see a serious problem with this path forward? Thanks, Chris & Acee. LSR Chairs.
