Subject: [EXTERNAL] BoF proposal: Evaluate impact of MAC address randomization to IP applications


Jason, Jason, Yiu,



Based on the previous email thread, may I suggest a couple of items to improve the BoF proposal (wiki/agenda) ?

- I guess that there will be more than 50 people based on the initial reactions

- adding capport as conflict to be avoided for the BoF

[YL] Can you elaborate?



- adding a link to draft-lee-randomized-macaddr-ps

[YL] Will do



- assuming that it is too early to form a WG, please state the status of ‘non WG forming’

[YL] Noted



- putting  the description & agenda on the wiki https://trac.tools.ietf.org/bof/trac/wiki<https://urldefense.com/v3/__https:/trac.tools.ietf.org/bof/trac/wiki__;!!CQl3mcHX2A!RSXmaxkBH6JCErvEmGGD7luqaqCDc3f9wIiM6WRHvkBmPZqaeFNHBe8PHAbsvGE$> before this Friday 2nd of October deadline

[YL] Will work on it tomorrow.



- starting to find a potential chair who is not a proponent

[YL] Ok



- Adding discussion about privacy impact on the agenda is important or even critical

[YL] OK



- adding IEEE coordination is also important (could be handled before the potential BoF)

[YL] JW will help here.





More specific to draft-lee-randomized-macaddr-ps-01, here are a couple of comments (mostly details):

  *   MAC addresses are not always 48 bits long
  *   MAC addresses are not always assigned by manufacturers (think VM)
  *   Suggest to distinguish between ‘stable’ and ‘static’ and ‘persistent’ MAC address
  *   Of course BCP 14 is no more RFC 2119 ;-)
  *   PS-04 is more a requirement than a problem statement

[Y] We will add these to 02.





Hope this helps and happy to continue the discussion of course ;-)

[YL] Thanks!





-éric
