We've had the authors of the individual conflicting drafts take a shot at merging their work.
This has failed. Here is the full history (which I also summarized during IETF103 as well). I will send a second email discussing this. - Jan 2, 2018 Publication: draft-li-dynamic-flooding and drfat-li-dynamic-flooding-isis published centralized solution. - Mar 5, 2018 Publication: draft-cc-isis-flooding-reduction and draft-cc-ospf-flooding-reduction published distributed solution. - mention of centralized solution asserting it is not good choice. - IETF 101 (Mar 2018) - Video: https://www.youtube.com/watch?v=qHmT4ytMn4w&list=PLC86T-6ZTP5j_HaBNdfPbgxGIp22cnaWS - Minutes: https://datatracker.ietf.org/meeting/101/materials/minutes-101-lsr-00 - draft-li-dynamic-flooding-02 presented (1 author). at IETF 101 - Generally well received. - draft-cc-ospf-flooding-reduction-00 (4 authors) presented. - Serious problems immediately found during presentation -- not fully baked. - Mar 18, 2018 draft-li-dynamic-flooding-03 published (1 author) - Mar 27, 2018 draft-li-dynamic-flooding-04 published (1 author) - Apr 20, 2018 draft-cc-ospf-flooding-reduction-01 revised - Jun 28, 2018 draft-li-dynamic-flooding-05 published (2 authors) - *SMALL CHANGE TO SUPPORT DISTRIBUTED ALGORITHM*. - Does not specify distributed algorithm only how to indicate one in use, small change. - Jul 2, 2018 draft-cc-ospf-flooding-reduction-02 published - IETF 102 (Jul 14, 2018) - draft-li-dynamic-flooding-05 presented. - draft-cc-ospf-flooding-reduction-02 presented. - Sep 12, 2018 draft-cc-ospf-flooding-reduction-03 (4 authors) - *LARGE CHANGE ADDS NEW CENTRALIZED SOLUTION*. - Sep 20, 2018 draft-cc-ospf-flooding-reduction-04 (4 authors) - Oct 21, 2018 draft-li-lsr-dynamic-flooding-00 and -01 (5 authors) - IETF 103 (Nov 3, 2018) - Chairs give direction - draft-li-lsr-dynamic-flooding-05 having come first, being well written and not specifying a distributed algorithm (merely allowing for one) is the correct vehicle to adopt as a base document. - Distributed algorithm work (the original basis for draft-cc-ospf-flooding-reduction) should continue as a separate document form the base which would thus we have no conflicts. - In the meantime the authors try and merge work, this fails. - Dec 3, 2018 draft-li-lsr-dynamic-flooding-02 (7 authors) - Dec 10, 2018 draft-cc-lsr-flooding-reduction-00 (4 authors) - Jan 7, 2019 draft-cc-lsr-flooding-reduction-01 (8 authors)
