-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 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.
