VPP PERFORMANCE TESTS + + - **Service density 2n-skx tests**: Added higher NF density tests with + 802.1q (vlan) and VXLAN encapsulation from Traffic Generator. + + - **GBP tests**: Added GBP (Group Based Policy) routing test cases + with 802.1q (vlan) external traffic. + + - **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. + + - **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 + + - **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 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. + +.. raw:: latex + + \clearpage + +.. _vpp_known_issues: + +Known Issues +------------ + +List of known issues in |csit-release| for VPP performance tests: + ++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ +| # | JiraID | Issue Description | ++====+=========================================+==========================================================================================================+ +| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
