-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. **Added VPP performance tests**\r
-\r
- - **MRR tests** : New MRR tests measure the packet forwarding rate\r
- under the maximum load offered by traffic generator over a set\r
- trial duration, regardless of packet loss. Maximum load for\r
- specified Ethernet frame size is set to the bi-directional link\r
- rate. MRR tests are used for continuous performance trending and\r
- for comparison between releases.\r
-\r
- - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests\r
- verifying performance of Endpoint to SR-unaware appliance via\r
- masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS)\r
- functions.\r
-\r
-#. **Presentation and Analytics Layer (PAL)**\r
-\r
- - Added continuous performance measuring, trending and anomaly\r
- detection. Includes new PAL code and Jenkins jobs for Performance\r
- Trending (PT) and Performance Analysis (PA) producing performance\r
- trending dashboard and trendline graphs with summary and drill-\r
- down views across all specified tests that can be reviewed and\r
- inspected regularly by FD.io developers and users community.\r
-\r
-#. **Test Framework Optimizations**\r
-\r
- - **Performance tests efficiency** : Qemu build/install\r
- optimizations, warmup phase handling, vpp restart handling.\r
- Resulted in improved stability and reduced total execution time by\r
- 30% for single pkt size e.g. 64B/78B.\r
-\r
- - **General code housekeeping** : ongoing RF keywords\r
- optimizations, removal of redundant RF keywords.\r
-\r
-Performance Changes\r
--------------------\r
-\r
-Relative performance changes in measured packet throughput in CSIT\r
-|release| are calculated against the results from CSIT |release-1|\r
-report. Listed mean and standard deviation values are computed based on\r
-a series of the same tests executed against respective VPP releases to\r
-verify test results repeatibility, with percentage change calculated for\r
-mean values. Note that the standard deviation is quite high for a small\r
-number of packet throughput tests, what indicates poor test results\r
-repeatability and makes the relative change of mean throughput value not\r
-fully representative for these tests. The root causes behind poor\r
-results repeatibility vary between the test cases.\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. 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.
+
+ - **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.
+
+ - **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.
+
+ - **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).
+
+#. TEST FRAMEWORK
+
+ - **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.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
+
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.

+| # | JiraID | Issue Description |
++====+=========================================+==========================================================================================================+
+| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
+| | <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-1503 | [`TRex-519 <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_] XL710/XXV710 with FW 6.0.1 will have |
+| | <https://jira.fd.io/browse/CSIT-1503>`_ | Rx drop rate of 27MPPS. |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
+| | <https://jira.fd.io/browse/CSIT-1498>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1499 | AVF tests are sporadically failing on initialization of AVF interface. |
+| | <https://jira.fd.io/browse/CSIT-1499>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 6 | `VPP-1676 | 9000B ip4 memif errors - ip4-input: ip4 length > l2 length. |
+| | <https://jira.fd.io/browse/VPP-1676>`_ | IP4 jumbo frames (9000B) are dropped in case of tests with memif. |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+

+| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 8 | `CSIT-1591 | 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-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ |
+| | `VPP-1763 | |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 9 | `CSIT-1592 | VPP memif API does not enable memif zero-copy, resulting in different memif configuration vs. previously |
+| | <https://jira.fd.io/browse/CSIT-1592>`_ | tested VAT/CLI where memif zero-copy was enabled by default. Needs to be fixed in VPP. |
+| +-----------------------------------------+ |
+| | `VPP-1764 | |
+| | <https://jira.fd.io/browse/VPP-1764>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 10 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
+| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 11 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
