Subject: [Lsr] Flooding Reduction Draft Redux
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:

- 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.
[HC] All the problems have been resolved in our latest draft.
Some people indicated that the distributed solution is better than the
centralized one. In addition, on the LSR mailing list, some people said that
the distributed solution is more practical.
- 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.
[HC] Coming first and being well written are important. However, technical
merits or advantages are at least equally important.
- 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)
