VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with - 802.1q (vlan) and VXLAN encapsulation from Traffic Generator. - - - **GBP tests**: Added GBP (Group Based Policy) routing test cases - with 802.1q (vlan) external traffic. - - - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and - scale test cases (Fortville NICs only). - - - **2n-skx tests**: Increased coverage of selected (COP, iACL, - Policer) test cases. + - **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. - - **IPsec scale tests**: Added IPsec interface mode scale tests with - 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels. - Removed DPDK backend dependency. Major IPsec test code - refactoring. - - - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP - performance tests using WRK generator talking to the VPP HTTP - static server plugin measuring connections per second and - requests per second. +#. TEST FRAMEWORK - - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q - encapsulation is now used on both links of SUT. Previously dot1q - was used only on a single link with the other link carrying - untagged Ethernet frames. This change results in slightly lower - throughput in CSIT-1908 for all dot1q tests in all 2-Node - testbeds. + - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and + SUTs. Included VPP perfmon plugin telemetry with all perfmon + bundles available in VPP release. - - **KVM VM vhost-user tests**: completed move to Kernel-VM for all - tests. In addition to running DPDK Testpmd as VM workload, new - tests created with VPP as VM workload. VPP in VM is the same - version as the DUT VPP (acting as vSwitch) and its configuration - depends on the test type. For all L2 Ethernet Switching tests - it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's - vpp-ip4 (VPP IPv4 routing). + - **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. -#. TEST FRAMEWORK + - **CSIT test environment** version has been updated to ver. 7, see + :ref:`test_environment_versioning`. - - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords - to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI). - Redesign of key components of PAPI Socket Executor and PAPI - history. Due to issues with PAPI performance, VAT is still used - in CSIT for all VPP scale tests. See known issues below. + - **CSIT in AWS environment**: Added CSIT support for AWS c5n + instances environment. Test results will be added in sub-sequent + CSIT-2106 report. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords and aligning of suite/test - setup/teardowns. + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues + below. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. #. PRESENTATION AND ANALYTICS LAYER - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **Graphs improvements**: Updated Packet Latency graphs, + see :ref:`latency_methodology`. .. raw:: latex @@ -73,46 +95,34 @@ Known Issues List of known issues in |csit-release| for VPP performance tests: -+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+==========================================================================================================+ -| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
