Re: [mpls] Poll 2: New SPL vs re-purposed ELI for carrying Network Action Indicators

Hi Chairs, 

I have one clarification comment about the statement below:

It is not clear whether you were referring to the indicator of the existence of any network action (and the optional associated data), or the indicator of a specific network action. My guess is you were talking about the former. 

The term for the former was Ancillary Data Indicator (ADI), in current mna framework draft it is called Network Action Sub-Stack Indicator (NSI), while my previous comment was that they are not equivalent.

The term for the latter is Network Action Indicator (NAI). 

Thus to avoid possible confusion with this poll, I'd suggest to avoid mentioning "network action indicator" in this question. In the mean time, the WG may also discuss how to pick a suitable term for it. 

Hope this helps.

Best regards,
Jie
