[spring] Re: Call for adoption: draft-jiang-spring-sr-policy-nrp-05 (Ends 2026-02-02)

["Zafar Ali (zali)" <[e-mail]>]

Dear authors and the WG,

Following up on the Spring WG session discussion:
This is the related comment I sent during the WG adoption process.

As clarified to question from Joel, the comment is related to the data plane (HW) implementation of the draft.

Thanks

Regards … Zafar

Dear authors, chairs and the WG

From the data model viewpoint, I would like to see the option to fix the NRP ID at the Policy level.

  *
NRP ID (NRP Policy) is related to the intent.
  *
When NRP ID has data plane representation, changing the NRP ID at the candidate path level on-the-fly when CP switchover happens may be non-trivial for implementation.


Thanks

This message starts a spring WG Call for Adoption of:
draft-jiang-spring-sr-policy-nrp-05

This Working Group Call for Adoption ends on 2026-02-02

Abstract:
   Segment Routing (SR) Policy is a set of candidate paths, each
   consisting of one or more segment lists and the associated
   information.  A Network Resource Partition (NRP), is a subset of the
   resources and associated policies in the underlay network.  In SR
   networks with multiple NRPs, an SR Policy can be associated with a
   particular NRP.  In that case, SR Policy can be used for steering and
   forwarding traffic which is mapped to the NRP, so that the packets
   can be processed with the subset of network resources and policy of
   the NRP for guaranteed performance.  Thus the association between SR
   Policy and NRP needs to be specified.

   This document defines extensions to the SR Policy Architecture to
   allow the association of the SR Policy candidate paths with NRPs.
