[Srcomp] Fw: New Version Notification for draft-srcompdt-spring-compression-requirement-06.txt, --about requirement of "SRv6 Base Coexistence"

[Weiqiang Cheng <[e-mail]>]

Hi team,

According to Chongfeng’s comments, we have got agreement on the minor change on draft-srcompdt-spring-compression-requirement several month ago. 

 

Darren,

Could you generate a new version of requirement draft with the update according to following mail?

 

B.R.

Hi， Li Cheng,

I  think your revision is fine.

Hi Chongfeng,

How about this? 

I removed the “existing”, and using simultaneous deployments

 

 <https://tools.ietf.org/html/draft-srcompdt-spring-compression-requirement-06#section-5.1> 5.1.  SRv6 Base Coexistence

 

 

   Description: The compression proposal MUST support simultaneous 

   deployment with SRv6 networks.

 

   Rationale: SRv6 is deployed today.  A compression proposal that

   interoperates well with SRv6, as deployed, will reduce the overhead

   and simplify operations.  For Network operators who would migrate to

   compressed SRv6 SID lists, the migration is expected to gradually

   occur over a period of time as they upgrade networks, domains, device

   families and software instances.

 

   Metric: A compliant compression proposal provides the following

 

   o  Supports simultaneous deployment at a node with current SRv6 SIDs.

   o  Supports simultaneous deployment at a node with current SRv6

      control plane.

   o  Supports simultaneous operation of current SRv6 paths with

      compressed paths.

   o  Supports the behaviors in

      [I-D.ietf-spring-srv6-network-programming <https://tools.ietf.org/html/draft-srcompdt-spring-compression-requirement-06#ref-I-D.ietf-spring-srv6-network-programming> ].

   o  Does not require removal of existing IPv6 address planning.

Hi，folks

I'd like to talk about requirement of "SRv6 Base Coexistence" in section 5.1.  The requirement is  described as "The compression proposal MUST support deployment in existing SRv6 networks." I think we should give a clear definition of "existing SRv6 network", some opertators have deployed SRv6, such as China Telecom,  if the software and hardware of the network equipment need to be changed to support compressed SRv6, it is not "existing SRv6 network" any longer, for it has changed the network itself.  If we stick to the current description of this requirement 5.1, I think NONE of the existing compressed slutions can meet this requiement, unless it does not change the network at all.

 

Best regards

Chongfeng

Thanks Weiqiang!

 

Yes, I think the document is mature for WG adoption.  Let's nail it down, and then progress the analysis in parallel.

 

Respect,

Cheng

Hi Group,

There were some comments on section 5.2 of draft-srcomdt-spring-compression-requirements-05 which is about the PS or BCP Compliance.

Design team had discussed the comments with group chairs. We believe it is about an IETF process, not a technical topic. 

So we removed the chapter and generated -06 revision.

 

So far, DT have resolved all the comments received and believe the draft is mature.

 

We would like to ask for WG Adoption call for draft.

 

B.R.

Weiqiang Cheng
