Re: CSIT-2106 Release Report is published

Caveat note :)

Number of the latency graphs in report show excessive numbers O(sec)
across frame sizes w/o and with load for both VPP and DPDK.

Few of us in CSIT are working on the resolution, stay tuned.
For now please ignore those numbers.

Hi All, CSIT-2106 report is now available on docs site:

Another successful release! Many thanks to all contributors in CSIT and
VPP communities for making it happen.

CSIT-2106 Release Summary


- AF_XDP: Added af_xdp driver support for all test cases. Test results
will be added in sub-sequent CSIT-2106 report.

- GTPU tunnel: Added GTPU HW Offload IPv4 routing tests.

- Intel Xeon Ice Lake: Added initial test data for these platforms.
Current CSIT-2106 report data for Intel Xeon Ice Lake comes from an
external source (Intel labs running CSIT code on
"8360Y D Stepping" and "6338N" processors).

- CSIT in AWS environment: Added CSIT support for AWS c5n instances
environment. Test results will be added in sub-sequent CSIT-2106

- 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. Implemented number of
optimizations improving rate discovery efficiency.


- Telemetry retouch: Refactored telemetry retrieval from DUTs and SUTs.
Included VPP perfmon plugin telemetry with all perfmon bundles
available in VPP release.

- Upgrade to Ubuntu 20.04 LTS: Re-installed base operating system to
Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker containers
used for spawning topology.
