Re: [Teas] WG adoption poll: draft-bestbar-teas-ns-packet-08

Hi Danielle, all,

These missing pieces are not specified in this draft but in each of the many individual drafts that are cited there. These individual drafts will have to be in Standards Track if the WGs owning these documents accept to publish them.

I checked the various IPR disclosures to see if there are specific sections that are indicated, but unfortunately there is nothing helpful out there. Only one disclosure indicates a reference to specific sections, but provides 2-6 (which is the full document!!).

For what we are doing in teas, I’m tempted to suggest that a ** new draft ** is edited with less details and dependency on these specific solutions. The document should be more architecture-oriented with a balanced discussion on the viable approaches to realize the slices. The document can identify the missing functionalities, of course.

Cheers,
Med

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.

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

[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?
