VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with two - NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now - used as a VNF payload similar to CNF tests. - - - **Soak Tests**: Optimized performamce soak tests framework - code for extended time duration tests and throughput discovery - at given PLR and at give total test time e.g. minutes, hours, - days, weeks. See updated - :ref:`test_methodology` section 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. #. TEST FRAMEWORK - - **Qemu code refactor**: Complete code refactor of the key components of - QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added - implementation of kernel-image-kvm based VM replacing the previously used - NestedVM images. Added ability to run VPP as a payload in VNF. + - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and + SUTs. Included VPP perfmon plugin telemetry with all perfmon + bundles available in VPP release. - - **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to - PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components - of PAPI Executor and PAPI history. + - **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. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **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 suite generator**: Added capability to generate suites for - different NIC models as well as throughput search algorithm types. Uses - base tests suites as source. + - **CSIT test environment** version has been updated to ver. 7, see + :ref:`test_environment_versioning`. - - **TOX verification**: Added verifications for test suite generator. + - **CSIT in AWS environment**: Added CSIT support for AWS c5n + instances environment. Test results will be added in sub-sequent + CSIT-2106 report. -#. PRESENTATION AND ANALYTICS LAYER + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues + below. - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. -.. - #.
