-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. Added VPP performance tests\r
-\r
- - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif**\r
-\r
- - Added tests with VPP vswitch in container connecting a number of VPP-\r
- in-container service chain topologies with L2 Cross-Connect and L2\r
- Bridge-Domain configurations, orchestrated by Kubernetes. Added\r
- following forwarding topologies: i) "Parallel" with packets flowing from\r
- NIC via VPP to container and back to VPP and NIC; ii) "Chained" (a.k.a.\r
- "Snake") with packets flowing via VPP to container, back to VPP, to next\r
- container, back to VPP and so on until the last container in a chain,\r
- then back to VPP and NIC; iii) "Horizontal" with packets flowing via VPP\r
- to container, then via "horizontal" memif to next container, and so on\r
- until the last container, then back to VPP and NIC;\r
-\r
- - **MRR tests**\r
-\r
- - <placeholder>;\r
-\r
- - **SRv6**\r
-\r
- - Initial SRv6 (Segment Routing IPv6) tests verifying performance of\r
- IPv6 and SRH (Segment Routing Header) encapsulation, decapsulation,\r
- lookups and rewrites based on configured End and End.DX6 SRv6 egress\r
- functions;\r
-\r
-#. Presentation and Analytics Layer\r
-\r
- - Added throughput speedup analysis for multi-core and multi-thread\r
- VPP tests into Presentation and Analytics Layer (PAL) for automated\r
- CSIT test results analysis;\r
-\r
-#. Other changes\r
-\r
- - **Framework optimizations**\r
-\r
- - Performance test duration improvements and stability;\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 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.
+
+#. 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.
+
+ - **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.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
+
+ - **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.
+
+ - **TOX verification**: Added verifications for test suite generator.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.
+
+#. MISCELLANEOUS
+
+ - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
+ dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
+ |csit-release| automated testing code.
+ Only graphs for Packet Throughput and Speedup Multi-core and not
+ for Packet Latency were published as there are no results for Packet
+ Latency available.
