Release Deliverables
| Name | Status | Jira Category | Description |
|---|---|---|---|
| Soak Tests | WIP | 1904-Framework | Fine tune soak throughput tests based on PLRsearch and extended test duration. Add comparison vs. NDR/PDR rates. |
| VPP Patch Performance Tests | WIP | 1904-Framework | Fine tune VPP patch vs. parent performance tests, degradation detection, gerrit voting. Add auto-trigger subject to physical testbeds' capacity. |
| CSIT PAPI Support | WIP | 1904-Framework | Move CSIT code from VAT to PAPI APIs, re-write of Level-1 Keywords. |
| NFV Density | WIP | 1904-Framework | Implement "thin-VM" with selectable NF workloads. Increase density matrix combination coverage. |
| 1n-arm VPP_Device | WIP | 1904-Framework | Bring up VPP_Device test environment on 1n-arm testbed(s). |

| VPP_Path | Open | 1904-Framework | Complete moving non-device-driver CSIT VIRL tests to VPP_Path (VPP make test) integration tests:
i) Required for functional acceptance of VPP feature path(s) driven by use case(s); ii) See P1 and P2 markup in CSIT_VIRL migration progress. |
| Per VPP node Perfmon | Open | 1904-Framework | Use new VPP perfmon plugin for per node compute efficiency telemetry. |

| 3n-arm Tests | WIP | 1904-Test | Port existing 2n-skx tests to 2n-arm environment. |
| 2n-dnv Tests | WIP | 1904-Test | Port existing 2n-skx tests to 2n-dnv environment. |
| AVF Driver Tests | Open | 1904-Test | 2n-skx: drive parity of test coverage with DPDK for all baseline and scale tests. |
| VPP_Device Arm | WIP | 1904-Test | 1n-arm: add device-driver focused tests (migration away from VIRL). |
| VPP_Device Denverton | Open | 1904-Test | 1n-dnv: add device-driver focused tests (migration away from VIRL). |
Jira Task Tracking
All CSIT release deliverables should be tracked in FDio CSIT Jira using one of the following Jira Epic categories:
- to be added
Multi-Release Work Areas
| Work Area | Description |
|---|---|
| Xeon Skx testbeds | Make Skylake performance test coverage complete:
i) Boost tests in 2-Node setups, complete 3-Node setups; ii) Complete Memif/Container and Vhost-user/VM with latest QEMU; iii) Push vpp-dev to Ubuntu 18.04. |
| Arm testbeds | Introduce Arm performance tests. |
| Atom testbeds | Introduce Denverton and Rangeley performance tests. |
| Better vhost, memif coverage | Produce more complete test data for NFV service density:
i) Scaled-out Vhost-user/VM and Memif/Container tests; ii) Test the same packet paths and NF topologies: service chains, service pipelines; iii) See if we can isolate the actual cost of Vhostuser-virtio and Memif-Memif virtual interfaces based on the test and system telemetry. iv) Test with VM and Containers running on a single Processor (single socket) with no core oversubscription and with. v) Extend the test over two Processors to quantify impact of UPI latency (and bandwidth). |
| VPP per patch performance tests | Productise per VPP patch performance tests with change detection, prepare for voting:
i) Improve detection accuracy and precision; ii) Nail down current results variance; iii) Apply improvements to continuous trending and (future) git auto-bisection. |
| Trending Improved Detection | Make trending job use new Burst MRR trending tests for better anomaly detection:
i) Currently postponed, as the algorithm detects performance changes not related to VPP code. ii) We need heavy workarounds or way more predictable SUT behavior. |
| More VPP telemetry reported and analysed | API based consumption of VPP telemetry including existing general counters, and future extended per node counters. |
| Evolve throughput search | Build upon MLRsearch and PLRsearch experience vs. ordinary binary search:
i) Compare MLRsearch with PLRsearch soak test results. |
| General enhancements | General CSIT and VPP performance test and infrastructure enhancements:
i) Productize VPP_Device container-based functional tests in 1-Node Skylake testbeds, assist with the same for Arm; ii) Add proper packet latency measurements with T-Rex HDRhistogram, push T-Rex to productize HDRh'gram; iii) Start using the new VPP stats infra for per test counters and "gauges" collection incl. "show runtime", instead of VPP show CLI; iv) Start migration from VAT to VPP Python API; v) Nail down "broken"/not-performing VPP data plane feature arcs (incl. multi-threading) indicated by CSIT-18.10 results data. |
