Hi Paul,
Thank you very much for taking the time to review the draft!
You are right in that the measurements / reported percentiles of
different network segments need to be the same to enable composability.
Ensuring this alignment across different networks / operators might be
challenging, especially considering that the draft does not impose
standardized percentiles for the network performance requirements of
applications.
The draft does follow BITAG recommendations regarding
measurement percentiles, though, and I think that once we have a better
understanding which measurement percentiles have the most meaning for
applications (with application “profiles" then also using those
percentiles), alignment across operators could very well just follow
naturally.
Even if it does not follow, there is still a lot of value to be gained
by just using the methodology on different network segments within the
same network.
I believe we already have some limited (implicit) text along this line
in the document. If you see value in clarifying possible deployment /
adoption challenges beyond what we currently have, we could add some
additional, explicit discussion focusing on this aspect in the
operational consideration section.
What do you think?
It was the existing text that mentions the need for alignment of
percentiles, in a different context, that led me to ask the question.
I do believe it is important to add a discussion about the challenges to
successful deployment, including the challenges to composability. How
useful will this method be without composability over the end-to-end
path? And how will that alignment be achieved?
Toward that end, it would be helpful if you included some important
use-cases. For instance, a way for an end user to obtain statistics for
their own network attachment, for the ways they use the network.
Regarding the presentation of the formulas, you have probably also seen
in the thread with Martin that we plan to (at the very least) implement
his suggestion that you also refer to in your comment. Additionally,
Martin has kindly provided me additional pointers for alternative forms
of formula rendering and we plan to also explore these options to come
up with a version that is as clear and easy to understand as possible.
I would very much appreciate your feedback on the final version once we
have it.
Yes, I have been following that. And will be happy to review the changes
you ultimately make.
Thanks,
Paul
