Dear Maciek,

I didn't mean to be rude, but you know how it feels when you see a community of professionals for specific software and no one could help.


I know that no one is obliged to help me, I was simply expecting more out of it.

My read is that folks are simply very busy, and number of people versed in ds-lite and other softwire technologies that VPP implements aplenty of, is not that large. So pls bear with this community, and keep trying. Someone wise once said "Energy and (constructive) persistence conquer all things”, especially when done with conviction of being right ;)

Dear Ameen,

What specific statement in the email do you disagree with?

This is not a research paper, it is CSIT release report capturing benchmarking and functional test data for v21.10 release.

Regarding your comment about "VPP and the system doesn't function”, I checked your statement about:

"I have asked here a million times about configuring ds-lite, no one helped.”

And found out that you have sent few emails (between 26-Sep and 28-Oct) to vpp-dev with questions about running ds-lite on vpp, and the last email was not answered.
I suggest you resend the email, and I am confident that dev community will provide you with support.

I would totally disagree.
It is disappointing when you base your research paper on VPP and the system doesn't function.
I have asked here a million times about configuring ds-lite, no one helped.

Hi All, CSIT-2110 report is now available on docs site:
Another successful release! Many thanks to all contributors in CSIT and
VPP communities for making it happen.
See below for CSIT-2110 release summary and pointers to specific
sections in the report.
Welcome all comments, best by email to csit-dev@....
CSIT-2110 Release Summary
- Intel Xeon Ice Lake: Added test data for these platforms. Current CSIT-2110
  report data for Intel Xeon Ice Lake comes from an external source (Intel
  labs running CSIT code on “8360Y D Stepping” and “6338N” processors).
- MLRsearch improvements: Added support for multiple packet throughput rates
  in a single search, each rate is associated with a distinct Packet Loss Ratio
  (PLR) criterion. Previously only Non Drop Rate (NDR) (PLR=0) and single
  Partial Drop Rate (PDR) (PLR<0.5%) were supported. Implemented number of
  optimizations improving rate discovery efficiency.
- TREX performance tests: Added initial tests for testing latency between 2
  ports on nic on the TRex. Added tests: IP4Base, IP4scale2m, IP6Base,
  IP6scale2m, L2bscale1mmaclrn.
- CSIT test environment version has been updated to ver. 8: Intel NIC 700/800
  series firmware upgrade based on DPDK compatibility matrix.
- CSIT in AWS environment: Added CSIT support for AWS c5n instances
