Body 
This liaison statement answers to IETFBMWG-LS3 (SG11-TD893/GEN).
https://datatracker.ietf.org/liaison/2097/

ITU-T Study Group 11 appreciates IETF BMWG's work and progress on Benchmarking
Methodology for Segment Routing, and thanks IETF BMWG WG for the invitation to
review the document.

Following its review, ITU-T SG11 has no comments to provide at this time.
ITU-T SG11 would like to inform IETF BMWG that SG11 has reached agreement on
the new Technical Report ITU-T QSTR.SRv6_Conf "Method for Verifying Conformance
to Segment Routing over IPv6".

ITU-T SG11 would also like to note that while ITU-T QSTR.SRv6_Conf aims to
develop test methods to verify a router's functional conformance to IETF RFCs
8402, 8754 and 8986, the IETF BMWG's work on Benchmarking Methodology for
Segment Routing aims to define a methodology for benchmarking the performance
of SRv6, with parameters such as Throughput, Buffer Size, Latency, Frame Loss,
System Recovery, Reset, and Scaling. These two work items therefore address
complementary aspects, i.e., functional conformance and performance
benchmarking, of the same technology (SRv6).

ITU-T SG11 appreciates IETF's continued efforts in developing Internet
standards and benchmarking methodologies and wishes IETF continued success in
this work.
