The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-rtgwg-backoff-algo/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I really like that you've produced this document. It was clear to someone with a minimal routing background. Thanks for that, too. I would support either Alvaro's Discuss or Deborah's Discuss, and maybe both. - I think the document would still be useful if it was Informational, as an example of the kind of thing that could be done. - If you really want stuff in the same network, or the same level/area, to use the same timers, putting safe-ish default values in the document would be more likely to make that happen. I did notice one piece of text that wasn't clear to me. I found this confusing - In general, when the network is stable, there is a desire to compute a new Shortest Path First (SPF) as soon as a failure is detected in order to quickly route around the failure. However, when the network is experiencing multiple temporally close failures over a short period of time, there is a conflicting desire to limit the frequency of SPF computations. Indeed, this allows a reduction in control plane resources used by IGPs and all protocols/subsystems reacting on the attendant route change, such as ... "this allows" seemed as likely to refer to the desire to limit, as anything else. Perhaps ... limit the frequency of SPF computations, which would allow a reduction in control plane resources used by IGPs and all protocols/subsystems reacting on the attendant route change, such as ... might be clearer.
