Hi Daniele,

 

I think Med’s point is that a document can say “If you implement this document, this is what you MUST do” but not “You MUST implement this document in order to achieve a general function.”

 

You actually said this (“it doesn’t have to be THE only solution”) but that was contradicted when you said “if you want to do network slicing in packet technologies, this is what you MUST do”.

 

Cheers,

Adrian

Hi Med,

 

If nothing new is defined and just existing tools are re-used I agree with you, but any addition that requires a different behavior in a node, like parsing differently the label stack or adding a new field to a packet requires a standard track.

 

Cheers

Daniele

Hi Daniele, 

 

I don’t think that an IETF document can mandate how a network can implement a slice.

 

We can of course document approaches that are likely to be implemented. We can hint some preference, e.g., leverage existing solutions with very minor changes. But all that is still informational in nature.

 

Cheers,

Med

Hi Med, Pavan,

 

Provided that I share concerns about the number of IPRs, I don’t think that the draft as is today can be considered informational.

Probably some work might be done to turn it into informational but the real question, do we want yet another informational draft or do we want one documents that says: “if you want to do network slicing in packet technologies, this is what you MUST do” ? it doesn’t have to be THE only solution but is should be one of the FEW solutions.

 

Cheers,
Daniele

Med, Hi!

 

>> The more I read draft-bestbar-teas-ns-packe, the more I’m convinced that it should not be in Standards Track, but Informational.

 

We (authors) would be okay with whatever the WG consensus is on this. 

 

Regards,

-Pavan

Hi all,

 

Focusing on this important point which should BTW be linked to the IPR point raised in one of my reviews + Adrian’s review. 

 

Other approaches that do not require major changes were already called out in this thread. I hope a balanced approach will be adopted to discuss/document them. 

 

The more I read draft-bestbar-teas-ns-packe, the more I’m convinced that it should not be in Standards Track, but Informational.

 

Cheers,

Med

[snip]

 

[AF] OK. Well, I think this document is showing that a lot of changes are needed in the network to support slicing in the form you envisage. I find that disappointing and think it would be nice to be able to support slicing on top of today’s packet networks with minimal changes. Did anyone think about how to do that?
