VPP PERFORMANCE 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). For details about the - physical setup see :ref:`tested_physical_topologies`. Tested - VPP and CSIT versions are pre-release, VPP - 21.06-rc0~779-gd640ae52f. - - - **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. - - - **Reduction of tests**: Removed obsolete VPP use cases and - superfluous test combinations from continuous and report test - executions, including: - - - All vts tests, obsolete use cases. - - dot1q tests apart from dot1q-l2bd, superfluous combinations. - - -100flows, -100kflows in all acl tests. - - nat44 tests - - - -pps tests, replaced by -tput tests. - - h1-p1-s1 single session tests, unessential combination. - - h4096-p63-s258048 tests, unessential scale combination. - - - ipsec tests - - - ethip4ipsectptlispgpe. - - policy-aes128gcm. - - policy-aes128cbc-hmac256sha. - - policy-aes128cbc-hmac512sha. - - int-aes128cbc-hmac256sha. - - scale of - - - 400tnlsw. - - 5000tnlsw. - - 20000tnlsw. - - 60000tnlsw. + - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel + Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node + Denverton) testbeds. + + - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx + testbeds. + + - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr + testbeds) and using built-in hardware crypto QAT device (3n-snr testbed + only). + + - **Reduction of tests**: Removed certain test variations executed + iteratively for the report (as well as in daily and weekly + trending) due to physical testbeds overload. #. TEST FRAMEWORK - - **CSIT test environment** version has been updated to ver. 8, see + - **CSIT test environment** version has been updated to ver. 11, see :ref:`test_environment_versioning`. - - **CSIT in AWS environment**: Added CSIT support for AWS c5n - instances environment. + - **TCP tput profiles** have to be changed, as newer TRex versions + are not deterministic enough when deciding when to send an ACK. - - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is - still used in CSIT for all VPP scale tests. See known issues - below. + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, VPP CLI is used in CSIT for many VPP scale + tests. See :ref:`vpp_known_issues`. - **General Code Housekeeping**: Ongoing code optimizations and bug fixes. #.
