#. VPP PERFORMANCE TESTS
- - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
- configurable trial duration and number of consecutive executions.
- Coverage of MRR tests has been extended across more test
- scenarios. MRR tests are used for continuous performance trending
- and for comparison between VPP releases.
-
- - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
- for all NDR and PDR throughput tests. All tests that previously
- used binary search got converted to MLRsearch. Coverage of NDR/PDR
- tests has been extended across more test scenarios.
-
- - **L2patch Tests**: Tests measure performance of VPP L2patch, the
- fastest L2 forwarding path implemented in VPP, that cross-links
- RX and TX of two physical interfaces.
-
- - **2-Node Tests**: A new baseline set of 2-node tests covering base
- ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
- testbeds.
+ - **Service density 2n-skx tests**: Added higher NF density tests with
+ 802.1q (vlan) and VXLAN encapsulation from Traffic Generator.
- - **Generated tests**: Simplified and unified test structure, semi-
- autogenerated by generator script. Test generator is currently
- able to create test combinations with various frame size and
- cores combinations. All existing test cases were converted to new
- format.
-
- - **Simultaneous Multi-Threading**: SMT-aware detection of server
- processor operation mode (HyperThreading enabled/disabled) with
- associated compute resource configuration including thread
- affinity, number of Rx queues and DPDK I/O mbufs. Tests are
- automatically tagged during execution to indicate executed thread
- configuration.
-
- - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
- physical testbed topologies based on the new SuperMirco servers
- each with two Intel Xeon Skylake Platinum processors. Full
- Ansible playbooks refactor for quick server (re)installation and
- reference pointers of configuration.
+ - **GBP tests**: Added GBP (Group Based Policy) routing test cases
+ with 802.1q (vlan) external traffic.
-#. PRESENTATION AND ANALYTICS LAYER
+ - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and
+ scale test cases (Fortville NICs only).
+
+ - **2n-skx tests**: Increased coverage of selected (COP, iACL,
+ Policer) test cases.
+
+ - **IPsec scale tests**: Added IPsec interface mode scale tests with
+ 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels.
+ Removed DPDK backend dependency. Major IPsec test code
+ refactoring.
+
+ - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
+ performance tests using WRK generator talking to the VPP HTTP
+ static server plugin measuring connections per second and
+ requests per second.
+
+ - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q
+ encapsulation is now used on both links of SUT. Previously dot1q
+ was used only on a single link with the other link carrying
+ untagged Ethernet frames. This change results in slightly lower
+ throughput in CSIT-1908 for all dot1q tests in all 2-Node
+ testbeds.
- - **Performance trending**: Further improvements of continuous
- performance trending, anomaly detection and analysis.
+ - **KVM VM vhost-user tests**: completed move to Kernel-VM for all
+ tests. In addition to running DPDK Testpmd as VM workload, new
+ tests created with VPP as VM workload. VPP in VM is the same
+ version as the DUT VPP (acting as vSwitch) and its configuration
+ depends on the test type. For all L2 Ethernet Switching tests
+ it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's
+ vpp-ip4 (VPP IPv4 routing).
-#. TEST FRAMEWORK OPTIMIZATIONS
+#. TEST FRAMEWORK
+
+ - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
+ to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
+ Redesign of key components of PAPI Socket Executor and PAPI
+ history. Due to issues with PAPI performance, VAT is still used
+ in CSIT for all VPP scale tests. See known issues below.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
+
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.
