[TICTOC]Re: Zaheduzzaman Sarker's No Objection on draft-ietf-tictoc-ptp-enterprise-profile-26: (with COMMENT)

[Doug Arnold <[e-mail]>]

I can rewrite the NOT ALLOWEDs as MUST NOTs.  Not sure what was going on in my head that day when I created a new normative phrase.

Hello Zaheduzzaman,

Thank you for your comments on the draft.  I give my answers inline below.


# Please define Grandmaster more precisely and consistently. In the
introduction is says - Grandmaster = active reference time source and in the
terminology section is says Grandmaster =  primary timeTransmitter Clock. lets
decide which one it is.



I tried to keep the intro more general and less laden with the PTP jargon, but you have a point.  I propose:

  *   Leave the introduction as it is.
  *   Change the definition to: The TimeTransmitter Clock that is currently acting as the reference time source of the PTP domain.

This works for me.



I am also wondering why we are using the term
"Grandmaster". The term "primary reference timeTransmitter" would it clear
about the role, why do we need to hide it? (And while the goal is to use
inclusive language - GrandMASTER has a master in it.)



IEEE 1588g, the amendment that recommends alternative terminology for PTP port states, retains the term grandmaster.  (note the ITU-T and SMPTE standards organizations changed PTP language, but also retained grandmaster).



The rationale for this was that the word master has two meanings, one denoting control, and one denoting knowledge or expertise. For examples of the second meaning, one can master a subject or get a Masters degree.  Grandmaster refers to the expertise meaning. As in grandmaster in chess or martial arts. The term Grandmaster was never associated with the institution of slavery.

I am fine with it if we want to follow what is retained in the IEEE 1588g, but I still think this word is not that helpful on describing its role.




# What are "Grandmaster Clusters" and how do we interpret "NOT ALLOWED"?



This is an optional PTP feature defined in IEEE 1588.  Since it is rarely implemented in network equipment, I thought it best not to allow its use in this profile.

I think then you better define "Grandmaster Clusters" in the terminology section of this draft or use reference to IEEE specification. And "NOT ALLOWED" is not defined as normative text in RFC 2119, hence you would need to use MUST NOT or NOT RECOMMENDED depending on what you exactly want to express.




Regards,

Doug

Thanks for working on this specification.

I have following comments which I believe would help improving document when
addressed -
