Changes in CSIT |release|\r
-------------------------\r
\r
-#. Test environment changes in VPP data plane performance tests:\r
-\r
- - Further characterization and optimizations of VPP vhost-user and VM test\r
- methodology and test environment;\r
-\r
- - Tests with varying Qemu virtio queue (a.k.a. vring) sizes:\r
- [vr256] default 256 descriptors, [vr1024] 1024 descriptors to\r
- optimize for packet throughput;\r
-\r
- - Tests with varying Linux :abbr:`CFS (Completely Fair Scheduler)`\r
- settings: [cfs] default settings, [cfsrr1] :abbr:`CFS (Completely Fair\r
- Scheduler)` RoundRobin(1) policy applied to all data plane threads\r
- handling test packet path including all VPP worker threads and all Qemu\r
- testpmd poll-mode threads;\r
-\r
- - Resulting test cases are all combinations with [vr256,vr1024] and\r
- [cfs,cfsrr1] settings;\r
-\r
- - For more detail see performance results observations section in\r
- this report;\r
-\r
-#. Code updates and optimizations in CSIT performance framework:\r
+#. Added VPP performance tests\r
\r
- - Complete CSIT framework code revision and optimizations as descried\r
- on CSIT wiki page `Design_Optimizations\r
- <https://wiki.fd.io/view/CSIT/Design_Optimizations>`_.\r
+ - **Container Topologies Orchestrated by K8s with VPP memif tests**\r
\r
- - For more detail see the :ref:`CSIT Framework Design <csit-design>` section\r
- in this report;\r
+ - Added tests with VPP in L2 Cross-Connect and Bridge-Domain\r
+ configurations containers, with service chain topologies orchestrated by\r
+ Kubernetes. Added following forwarding topologies: i) "Parallel" with\r
+ packets flowing from NIC via VPP to container and back to VPP and NIC;\r
+ ii) "Chained" a.k.a. "Snake" with packets flowing via VPP to container,\r
+ back to VPP, to next container, back to VPP and so on until the last\r
+ container in chain, then back to VPP and NIC; iii) "Horizontal" with\r
+ packets flowing via VPP to container, then via "horizontal" memif to\r
+ next container, and so on until the last container, then back to VPP and\r
+ NIC;.\r
\r
-#. Changes to CSIT driver for TRex Traffic Generator:\r
+ - **VPP TCP/IP stack**\r
\r
- - Complete refactor of TRex CSIT driver;\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
- - Introduction of packet traffic profiles to improve usability and\r
- manageability of traffic profiles for a growing number of test\r
- scenarios.\r
+ - **SRv6 tests**\r
\r
- - Support for packet traffic profiles to test IPv4/IPv6 stateful and\r
- stateless DUT data plane features;\r
+ - Initial SRv6 tests verifying performance of SRv6 encapsulation and\r
+ decapsulation and SID lookups.\r
\r
-#. Added VPP performance tests\r
+ - **IPSecSW tests**\r
\r
- - **Linux Container VPP memif virtual interface tests**\r
+ - SW computed IPSec encryption with AES-GCM, CBC-SHA1 ciphers, in\r
+ combination with IPv4 routed-forwarding.\r
\r
- - New VPP Memif virtual interface (shared memory interface) tests\r
- with L2 Bridge-Domain switched-forwarding;\r
+#. Presentation and Analytics Layer\r
\r
- - **Stateful Security Groups**\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
- - New m-thread m-core VPP stateful security-groups tests;\r
+#. Other improvements\r
\r
- - **MAC-IP binding**\r
+ - **Framework optimizations**\r
\r
- - New MACIP iACL single-thread single-core and m-thread m-core tests;\r
+ - Ability to run CSIT framework on ARM architecture.\r
\r
- - Statistical analysis of repeatibility of results;\r
+ - Overall stability improvements.\r
