Dear Massimo,


My apology for late reply. Both your comments are very valid. packetDeltaCount(IE2) can be also used for loss measurement. As well flowEndSeconds(IE151), flowEndMilliseconds(IE153),flowEndMicroseconds(IE155) or flowEndNanoseconds(IE157) for delay measurement. Both has been added in the -01 revision of the document.

Best wishes
Thomas

Hi Thomas,
thank you for your feedback.
I have a couple of comments.
In section 6.1 for IPFIX, in order to calculate loss you said to use for packets the entity octetDeltaCount(IE1). But might it be better to use the entity packetDeltaCount(IE2)?

Moreover I suggest for the delay to add the use of existing entities flowEndSeconds, flowEndMilliseconds, flowEndMicroseconds, flowEndNanoseconds.

Best Regards,

Massimo

Subject: [EXT] [ippm] Section 6 - draft-fz-ippm-alt-mark-deployment-01

Dear draft-fz-ippm-alt-mark-deployment authors, Dear IPPM working group,

First of all I think draft-fz-ippm-alt-mark-deployment is a valuable document describing the deployment of Alternat Marking.

I have reviewed https://datatracker.ietf.org/doc/draft-fz-ippm-alt-mark-deployment/ the Network Telemetry aspect described in Section 6 and wrote a proposal for -01 as following:

https://raw.githubusercontent.com/network-analytics/draft-fz-ippm-alt-mark-deployment/main/draft-fz-ippm-alt-mark-deployment-01.txt
https://raw.githubusercontent.com/network-analytics/draft-fz-ippm-alt-mark-deployment/main/draft-fz-ippm-alt-mark-deployment-01.xml

The new section describes how the export could be performed with existing IPFIX entities where decomposition is performed at the data collection and what needs to be consider for new IPFIX entities. I also described the publication with YANG push and what needs to be considered in terms of subscription, data publication and modeling.

Here the current diff: https://author-tools.ietf.org/diff?url_1=https://www.ietf.org/archive/id/draft-fz-ippm-alt-mark-deployment-00.txt&url_2=https://raw.githubusercontent.com/network-analytics/draft-fz-ippm-alt-mark-deployment/main/draft-fz-ippm-alt-mark-deployment-01.txt

I hope this makes sense and is helpful for the community. Feedback and comments welcome.

Best wishes
Thomas
