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).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.
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.
