Hi authors and all,
 
  
 
As promised during the IETF, I would like to provide additional comments about 
the draft.
 
Items 2 and 3 both say about  a SR Policy, similarly 4.2 that also pays 
attention for the long SID list. However forwarding performance tests (6) do 
not explicitly mention: which method DUT should use for 'SID stack 
construction' (as per 4.2).
 
[PV] We can mention in section 6 the possibility to test more construction 
methods and report the results as specified in section 5 on the reporting 
format (where a parameter is already defined).
 BKH> sounds good for me.  
Thus I would suggest to separate a SR Policy on a source edge node in a 
specific subcase (abstracting from the way to provision it - could be any) and 
define more detailed testing methodology, i.e. defining the way how to steer 
traffic into SR Policy, measuring the performance and LB ratio starting from 1 
CP, 1 SL with 2 SIDs, then up to MSD, testing ECMP/wECMP amongst NxSLs (i.e. 
16, 32, 64,128) with different number of SIDs and frame sizes (4.3). The goal 
is to compare SR Policy performance with other methods, check ECMP/wECMP limits 
and correct SR Policy work overall. 
 [PV] Do you mean to test a single SR policy on a source edge node with more 
construction methods (to check, for example, what is the more performant) or to 
test more SR policies at the same time (to check the overall ECMP performance)?
BKH> I meant testing one SR Policy with 1 active CP but with variable SLs 
number, SIDs, weights. I can unicast more detailed test description to you.
  
 
SY,
 
Boris

Abstract:
 
  
 
  This document defines a methodology for benchmarking Segment Routing
 
  (SR) performance for Segment Routing over IPv6 (SRv6) and MPLS (SR-
 
  MPLS).  It builds upon RFC 2544, RFC 5180, RFC 5695 and RFC 8402.
