Changes in CSIT |release|\r
-------------------------\r
\r
-#. VPP performance test environment changes\r
+#. Added VPP performance tests\r
\r
- - Further optimizations of VM and vhost-user test environment - various\r
- Qemu virtio queue size testing with value of 256 and 1024. Applied\r
- Linux CFS optimization to run VPP worker threads and Qemu worker threads\r
- with highest priority.\r
+ - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif**\r
\r
-#. VPP performance test framework changes\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
- - Full code review, optimization and refactor.\r
+ - **VPP TCP/IP stack**\r
\r
-#. T-rex changes\r
+ - Added tests for VPP TCP/IP stack using VPP built-in HTTP server.\r
+ WRK traffic generator is used as a client-side;\r
\r
- - Full refactor of T-rex driver and introduce of traffic profiles that\r
- improves readability, manageability of traffic profiles for various\r
- test scenarios.\r
+ - **SRv6**\r
\r
-#. Added VPP performance tests\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
- - **LXC memif**\r
+ - **IPSecSW**\r
\r
- - Memif interface tests interconnecting two VPP instances on single SUT.\r
- Master VPP instance running on native OS with Intel x520 NIC and guest\r
- VPP instance running in Linux Container (LXC) doing the L2 cross\r
- connect loop. LXC running in privileged mode is pinned to dedicated\r
- cores. All VPP instances are same version.\r
+ - SW computed IPSec encryption with AES-GCM, CBC-SHA1 ciphers, in\r
+ combination with IPv4 routed-forwarding;\r
\r
- - **Stateful Security Groups**\r
+#. Presentation and Analytics Layer\r
\r
- - **VM vhost use cases**\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
-Performance Improvements\r
-------------------------\r
+#. Other changes\r
\r
-Substantial improvements in measured packet throughput have been\r
-observed in a number of CSIT |release| tests listed below, with relative\r
-increase of double-digit percentage points. Relative improvements are\r
-calculated against the test results listed in CSIT |release-1| report.\r
-VPP-16.09 numbers are provided for reference.\r
+ - **Framework optimizations**\r
\r
-NDR Throughput\r
-~~~~~~~~~~~~~~\r
+ - Ability to run CSIT framework on ARM architecture;\r
\r
-Non-Drop Rate Throughput discovery tests:\r
+ - Overall stability improvements;\r

+ - **NDR and PDR throughput binary search change**\r
\r
-PDR Throughput\r
-~~~~~~~~~~~~~~\r
+ - Increased binary search resolution by reducing final step from\r
+ 100kpps to 50kpps;\r
\r
-Partial Drop Rate thoughput discovery tests with packet Loss Tolerance of 0.5%:\r
+ - **VPP plugin loaded as needed by tests**\r

+ - From this release only plugins required by tests are loaded at\r
+ VPP initialization time. Previously all plugins were loaded for\r
+ all tests;\r
\r
-Measured improvements are in line with VPP code optimizations listed in\r

-Other Performance Changes\r
--------------------------\r
+Performance Changes\r
+-------------------\r
\r
-Other changes in measured packet throughput, with either minor relative\r
-increase or decrease, have been observed in a number of CSIT |release|\r
-tests listed below. Relative changes are calculated against the test\r
-results listed in CSIT |release-1| report.\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
