Release Notes
=============
#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
-
- - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to Ubuntu
- 20.04.2 LTS. Upgrade includes also baseline Docker containers used for
- spawning topology.
-
- - **AF_XDP**: Added af_xdp driver testing for all testcases.
+ - **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.
- - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
+#. TEST FRAMEWORK
- - **Telemetry retouch**: Redesign telemetry retrieval from DUT. Include
- VPP perfmon plugin telemetry.
+ - **CSIT test environment** version has been updated to ver. 8, see
+ :ref:`test_environment_versioning`.
-#. TEST FRAMEWORK
+ - **CSIT in AWS environment**: Added CSIT support for AWS c5n
+ instances environment.
- **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
+ still used in CSIT for all VPP scale tests. See known issues
+ below.
- - **General Code Housekeeping**: Ongoing code optimizations,
- speed ups and bug fixes.
