To clarify, the email to which folks are responding is not an adoption poll from the chairs.  It is a solicitation of itnerest to the WG by the authors.  This is a step required before adoption.  The chairs will note that these replies are indications of interest.   For the chairs, the latter parts of the email below are significantly helpful.

Yours,

Joel

Hi WG,


I support the adoption of this draft. The proposed architecture is well-structured and comprehensive, encompassing the control, management, forwarding and application planes, and defines the essential components required for SFC implementation.

    *主题:*[spring] Adoption request for 
draft-watal-spring-srv6-sfc-sr-aware-functions

    Dear SPRING WG,

    I would like to request WG adoption of the following Internet-Draft:

    * Title: SRv6 SFC Architecture with SR-aware Functions
    * URL:
    
https://datatracker.ietf.org/doc/draft-watal-spring-srv6-sfc-sr-aware-functions/

    This document describes an SRv6 SFC architecture with SR-aware
    functions, based on existing SRv6 mechanisms. No new protocol
    extensions are defined.

    The draft has been presented and discussed in previous SPRING WG
    sessions, including at IETF 124:
    *
    
https://datatracker.ietf.org/meeting/124/materials/slides-124-spring-srv6-sfc-architecture-with-sr-aware-functions-00.pdf

    The architecture has also been validated through implementations
    demonstrated at recent IETF Hackathons, including:

    * Flow-based SR Policy classification using BGP Flowspec in GoBGP
    * SRv6 Policy and loose source routing support for SFC in Pola PCE
    * BGP-LS Service Segment extensions implemented in GoBGP and ExaBGP
    * A manager implemented using OpenStack and Ansible

    The corresponding Hackathon material is available at:
    * IETF 124 Hackathon:
    
https://datatracker.ietf.org/meeting/124/materials/slides-124-hackathon-sessd-srv6-sfc-architecture-with-sr-aware-functions-00.pdf

    We would appreciate the WG's feedback and consideration for adoption.

    Best regards,
