Hi folks,

Since there is a possibility that I will not make it to the
meeting on time today, I would like to share my thoughts here.

1. NTP over PTP
@Miroslav: Thanks for adding the requested content.
I have one small comment: In chapter 2 (PTP transport for NTP)
it would be worth mentioning that the values (e.g. lengthField)
are in network byte order.

However, this is optional, as it should be in the IEEE 1588 standard.
From my point of view the draft is ready and I give my ok for it :)

2. NTS for PTP
The implementation is making progress and I plan to integrate and
test NTS4PTP in LinuxPTP in early March. The draft will be updated
accordingly and in 2-3 weeks there will be a draft update. After
that I would like to migrate NTS4PTP as an IETF working group draft
document (draft-ietf-nts-for-ptp-00).

What do you think about this?

3. Roughtime and NTPv5 requirements
I haven't had much time in the last days to read the latest
mailinglist discussions. So I can't give any further feedback
at the moment.

Best regards,
