Changes in CSIT |release|\r
-------------------------\r
\r
-#. Added VPP performance tests\r
+#. **VPP performance tests**\r
\r
- - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif**\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
- - 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
+ - *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
- - **MRR tests**\r
+#. **Presentation and Analytics Layer**\r
\r
- - <placeholder>;\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
- - **SRv6**\r
+#. **Test Framework Optimizations**\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
+ - *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
-#. 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
+ - *General code housekeeping* - ongoing RF keywords optimizations,\r
+ removal of redundant RF keywords.\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
