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). 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)?
