Hi Reza.

Not sure why we need to know that, mostly from a perspective of orthogonality.  We (in terms of defining a Transport Slice) only need to know what the requirements are for a specific application, where the fact that the application may be a higher-layer control function for an “end-to-end” network slice does not even rise to the level of interesting information.

Thanks Eric and John for your comments.

In my opinion we need to have some materials to show clearly how “Transport Slice” is related to the overall e2e network slice. And also shows that “Transport Slice” is not same as “e2e network slice” and they are different.

We can revise the exiting text to make it more concise. Everyone can help with this.

Reza

I agree with John, at least to the extent that we should limit discussion of “end-to-end” slice management to just that much that we need to know to understand that there will likely be a higher-level management/configuration/orchestration/controller/etc. system that needs specific support for creating/modifying/removing Transport Slices – likely at several points in an “end-to-end” network slice, whatever that might mean.

I don’t think we even need to – or should – define what an “end-to-end” network slice is, except as possible examples to provide a background for the remainder of our work, because we simply do not need to know that.

Hi,

There seems to be way too much emphasis on E2E slice management.

Yours Irrespectively,

Eric, Jari and all,



As per our discussion during yesterday’s DT meeting, attached are my contribution to the new NS Framework draft. A few notes:



  *   I was not able to add these to GitHub. As a result, I wrote them in XML. Both XML and TXT versions are attached.
  *   Eric and Jari, please add them to master document in GitHub
  *   After merge, please review and send your comments/feedbacks in mailing list.
  *   There are still a few sections that I would like to contribute. I will do it later.



Thanks,

Reza
