#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- 802.1q (vlan) and 802.1ad (vxlan) encapsulation from Traffic Generator.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
- - **GBP tests**: Added GBP routing test cases with 802.1q (vlan) external
- traffic.
+ - To identify performance changes due to VPP code changes from
+ v20.05.0 to v20.09.0, both have been tested in CSIT environment
+ ver. 5 and compared against each other. All substantial
+ progressions has been marked up with RCA analysis. See
+ :ref:`vpp_compare_current_vs_previous_release` and
+ :ref:`vpp_known_issues`.
- - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and scale
- test cases.
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
- - **2n-skx tests**: Increased coverage of selected (COP, iACL, Policer)
- test cases.
+ - See :ref:`geneve_methodology` for more details.
- - **IPsec scale tests**: Added IPsec interface mode scale tests with
- 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 tunnels. Removed DPDK
- backend dependency.
+ - **NAT44 tests**: Adapted existing and added new tests.
+
+ - Refactored NAT44 deterministic mode (nat44det) tests to use separate
+ det44 vpp plugin and to use the same scheme of inside and outside
+ addresses and ports, as used in new NAT44 endpoint-dependent mode tests.
+
+ - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir)
+ tests that measure packet throughput in one direction with usage of TRex
+ in stateless mode.
+
+ - Added new NAT44 endpoint-dependent mode CPS tests that measure
+ connections per second with usage of TRex in stateful mode.
+ UPD packet size is 64 bytes. Size of TCP control packets
+ is not configurable, please ignore the -64b- part of test names.
+
+ - Added new NAT44 endpoint-dependent mode PPS tests that measure
+ packets per second (control and data together) with usage of TRex
+ in stateful mode. UPD packet size is 64 bytes. Size of TCP
+ data packets is governed by the default MSS value, so most data packets
+ are 1460 bytes long, please ignore the -64b- part of test names.
+
+ - See :ref:`nat44_methodology` for more details.
+
+ - **IPSec async mode tests**: Added VPP performance tests for async crypto
+ engine.
+
+ - **AMD 2n-zn2 testbed**: New physical testbed type installed in
+ FD.io CSIT, with VPP and DPDK performance data added to CSIT
+ trending and this report.
+
+ - **AMD 2n-tx2 testbed**: New physical testbed type installed in
+ FD.io CSIT, with VPP and DPDK performance data added to CSIT
+ trending and this report.
#. TEST FRAMEWORK
- - **CSIT PAPI Support**: Finished 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. Currently the only exception is
- usage of VAT command for scale configuration.
+ - **TRex ASTF**: Added capability to run TRex in advanced stateful mode.
+
+ - **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 RF keywords optimizations,
removal of redundant RF keywords and aligning of suite/test
setup/teardowns.
+ - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC.
+ No tests run for this NIC as it is not present in FD.io CSIT lab yet.
#. 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**: Added possibility to use Gbps on Y-axis in
+ Packet Throughput and Speedup Multi-Core graphs, added unidirectional
+ mode to the Latency graphs.

+| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
+| | <https://jira.fd.io/browse/VPP-662>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
+| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1771 | IPv4 IPSEC 9000B packet tests had been failing when chained buffers were not supported. |
+| | <https://jira.fd.io/browse/CSIT-1771>`_ | This has been fixed on VPP side, but CSIT still needs to re-enable jumbo tests. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
+| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
+| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
+| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
+| | | interface link via i40e driver to up. |
+| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 7 | `CSIT-1760 | All Mellanox / rdma driver tests are failing on LF testbed28 while successfully run on other LF testbeds. |
