-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. **VPP performance tests**\r
-\r
- - *MRR tests* - New Maximum Receive Rate tests measure the packet\r
- forwarding rate under the maximum load offered by traffic\r
- generator over a set trial duration, regardless of packet loss.\r
- MRR tests are used for continuous performance trending and for\r
- comparison between releases.\r
-\r
- - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy\r
- tests measure performance of SRv6 Endpoint fronting SR-unaware\r
- appliance via masquerading (End.AM), dynamic proxy (End.AD) or\r
- static proxy (End.AS) SR functions.\r
-\r
-#. **Presentation and Analytics Layer**\r
-\r
- - *Performance trending* - Added continuous performance trending and\r
- analysis. New Performance Trending and Performance Analysis jobs\r
- executed regular throughput tests, with results being subsequently\r
- analysed and trend and anomalies summarized and presented in VPP\r
- Performance Dashboard and trendline graphs.\r
-\r
-#. **Test Framework Optimizations**\r
-\r
- - *Performance tests efficiency* - Qemu build/install optimizations,\r
- warmup phase handling, vpp restart handling. Resulted in improved\r
- stability and reduced total execution time by 30% for single pkt\r
- size e.g. 64B/78B.\r
-\r
- - *General code housekeeping* - ongoing RF keywords optimizations,\r
- 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

-Throughput Trending\r
--------------------\r
-\r
-In addition to reporting throughput changes between VPP releases, CSIT\r
-provides continuous performance trending for VPP master branch:\r
-\r
-#. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_\r
- - per VPP test case throughput trend, trend compliance and summary of\r
- detected anomalies.\r
-\r
-#. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_\r
- - throughput test metrics, trend calculations and anomaly\r
- classification (progression, regression, outlier).\r
-\r
-#. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_\r
- - per VPP build MRR throughput measurements against the trendline\r
- with anomaly highlights, with associated CSIT test jobs.\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.
