[spring] WG Adoption call for https://datatracker.ietf.org/doc/draft-filsfilscheng-spring-srv6-srh-compression/

2021-10-01 Thread James Guichard
Dear WG: The chairs would like to express their appreciation for all the responses received to our emails with reference to how the working group wishes to move forward with respect to a solution for SRv6 compression. The apparent inclination of the working group is to use https://datatracker.

Dear WG Chairs, I have a question about the proposed note to be added if the document is adopted by the SPRING WG: Given that the working group has said that it wants to standardize one data plane solution, and given that the document contains multiple SRv6 EndPoint behaviors that some WG members

Chairs, I strongly object to the adoption of this draft. I also note that this is a very strange adoption call. The WG has indicated a preference for a single forwarding plane behavior. However, bullets #1 and #4 in the Call for Adoption suggest that the WG has yet to address whether the draft

CSID Authors, Assume that an SR path contains segments 1 through 8. Segments 1, 3, 5, and 7 are END SIDs that use Next-C-SID (i.e., uSID). Segments 2, 4, and 6 are END SIDs that use Replace-C-SID. Segment 8 is and END.DX4 SID. Please provide an example that shows us: * What the SRH looks

Sorry – but – I’m a little confused here. Because the way I look at this – the working group clearly stated that they wished for a single behavior – and this – does not deliver that – it is two separate behaviors. As such – I see this call for adoption – irrespective of the merits or lack ther

Hi Ron, Have you read this draft ? Quote from it: It is recommended for ease of operation that a single compressed encoding flavor be used in a given SRv6 domain. However, in a multi- domain deployment, different flavors can be used in different domains. On Fri, Oct 1, 2021 at 9:3

Folks, Draft-filsfilscheng-spring-srv6-srh-compression-02 introduces three new SID types that can occupy the Destination Address field of an IPv6 header. See Sections 4.1, 4.2, and 4.3 of the draft for details. The SPRING WG has issued a call for adoption for this draft. It is not clear that t

Just to add to this, I am one of the people who clearly stated that I didn’t think a single solution was the right answer here – and I stated my reasoning clearly on this list. I still believe that – however – I recognize that the foundation of the IETF is found in the bottom up consensus appr

All, As agreed by WG and reiterated by chairs during this adoption call WG agreed for a single data plane solution. That means that the proposed solution MUST be fully compliant with the specifications in [RFC8402], [RFC8754] and [RFC8986]. To me it does not mean that only a single flavor of th

Robert, I do remember that quote. And that is exactly why I ask the question! If NEXT-C-SID and REPLACE-C-SID are incompatible within a domain: * Can we say that they are a single behavior ? * Can we justify both because each is optimized for a different kind of network? * Can we j

Hi Ron, - Can we say that they are a single behavior ? No. And neither RFC8986 defines a single behavior or single flavor. Yet the bounds are clearly set what is the SRv6 data plane. For some strange reason I am observing here an attempt to squeeze different data plane into the room which i

Dear WG chairs, I agree with Greg Mirsky that the adoption guidelines are confusing and contradictory. Bullet #1 states that by expressing support for adoption the WG member is agreeing to adoption of a document that has multiple SRv6 compression solutions. On the other hand bullet #4 states th

Dear All, the update in this version describes the benefits of using BFD for multipoint networks (RFCs 8562 and 8563) over p2p MPLS LSP. Because RFC 8562 updated the BFD state machine, actors avoid the Init state and do not use the three-way handshake to advance the BFD session to the Up state. Thu

Hi Chairs & WG, I strongly support the adoption call. Regarding chair's note in the email, I would like to point that the network programming model (RFC8996) by nature defines multiple behaviors. CSID has a single SRv6 based data plane that defines the next and replace behaviors consistent
