[mpls] Re: Poll: IOAM and PSD

[Loa Andersson <[e-mail]>]

wg chairs, working group,

Preamble
--------
I have been a bit reluctant to respond to this poll, the reason is that 
I do not clearly see how mine (or anyone else) responses will be used. 
Will for example an "other application" that show up in a few weeks or 
months be able to make it on to the "preferred list" or will the second 
question be used to "close the line"?

I have had off-line discussions, and a impression that I have is that 
surprisingly many participants are not yet ready (sic!) to exclude 
anything, while they might have their preferences. Some of which I 
share, others not.

Haoyu correctly mention that we should align a closely as possible with 
existing standards, I concur.

My responses to the questions from the chairs

1. There are many flavors of IOAM.  Which ones would you like to 
deploy/implement with MNA? It is true that IOAM is flavour and feature 
rich. I have always thought that there is is a reason for this, e.g. 
while A and both can x and y, A is significantly better doing x, and B 
is significantly better doing y. I don't want to particularly exclude 
any flavour or feature. I believe that we need some information 
in-stack, e.g. "presence" and some OpCodes/flags. I also believe that
- IOAM Pre-allocated Trace (value 0) option in Post-Stack MNA
- IOAM Direct-Export (value 4) in Post-Stack MNA
      are valid starting points, while we should not take any action to 
disallow
      other options.

2. Do you have other applications of MNA that have not been proposed 
yet? No, if I had they would have been proposed :). I see that other 
responses tentatively lists "other applications", I think it is worth 
investigating those, and adopt if viable. I don't want a consolidated 
"no" response to this question to disallow "other applications" to be 
brought to the table. /Loa
