Re: [Idr] Adoption call for - draft-dong-idr-sr-policy-nrp-02 (3/1 to 3/14)

[Boris Hassanov <[e-mail]>]

 Hi Sue and all,I read  it and support the adoption of this draft.But with some comments. First of all agree with previous questions from Gyan and Dhruv (not only BGP use case but PCEP too, SR Algo and NRP, Section 3 definitely with MUST).Secondly, about association of NRP with SR Policy or a CP. As per RFC 9256 we have only one active CP in SR Policy, so what is the point for having other different NRPs for non active CPs?
Thank you.

This begins a 2 week WG adoption call for 
 
draft-dong-idr-sr-policy-nrp
 
https://datatracker.ietf.org/doc/draft-dong-idr-sr-policy-nrp/
 
  
 
Each of the authors should respond to this message with
 
an email indicating if they know of any IPR regarding this draft.
 
  
 
The draft specifies an extension to BGP SR policy to 
 
Specify the NRP (network partition resources) that 
 
Than an SR Policy candidate path is associated with. 
 
  
 
In your discussion consider if this is a useful addition to the
 
SR Policy candidate path. 
 
  
 
Cheerily, Sue 
 
  
 
===========
 
Full description from the draft 
 
  
   Segment Routing (SR) Policy is a set of candidate paths, each    consisting of one or more segment lists and the associated    information.  The header of a packet steered in an SR Policy is    augmented with an ordered list of segments associated with that SR    Policy.  A Network Resource Partition (NRP) is a subset of network    resources allocated in the underlay network which can be used to    support one or a group of IETF network slice services. 
  
 
   In networks where there are multiple NRPs, an SR Policy may be
 
   associated with a particular NRP.  The association between SR Policy
 
   and NRP needs to be specified, so that for service traffic which is
 
   steered into the SR Policy, the header of the packets can be
 
   augmented with the information associated with the NRP.  An SR Policy
 
   candidate path can be distributed using BGP SR Policy.  This document
 
   defines the extensions to BGP SR policy to specify the NRP which the
 
   SR Policy candidate path is associated with.
