VPP PERFORMANCE TESTS - - CSIT test environment is versioned, see - :ref:`test_environment_versioning`. - - - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels. - See :ref:`geneve_methodology` for more details. - - - - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio. - All tested topologies are compared with GSO enabled and disabled. - In |csit-release| there is only 1t1c tests running. - See :ref:`gso_methodology` for more details. - + - **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). 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. - - **NAT44 tests**: Added new test type, pure throughput tests. - They are similar to PPS tests, but they employ ramp-up trials - to ensure all sessions are created (and not timing out) - for performance trials. - - - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled - in ipsec suites. +#. TEST FRAMEWORK - - **Randomized profiles**: Improved repeatability and cycle length. - For details, see :ref:`packet_flow_ordering`. + - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and + SUTs.

Upgrade included also baseline Docker + containers used for spawning topology. - - **Framework speedup**: Shortened overall test job duration - by using a different test selection mechanism (using --test - instead of --include) and by avoiding unnecessary PAPI reconnects. + - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and + changed the way egress low latency queues are used in FVL NICs. + This broke latency measurements for majority of FVL NICs in + CSIT. Latency values look better after upgrading FVL FW on TRex + servers, but still somewhat higher than before the TRex upgrade. + Tracked by `CSIT-1790 `_. -#. TEST FRAMEWORK + - **CSIT test environment** version has been updated to ver. 7, see + :ref:`test_environment_versioning`. - - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode. + - **CSIT in AWS environment**: Added CSIT support for AWS c5n + instances environment.
