Release Deliverables

Name	Status	Jira Category	Description
3n-skx Tests	Open	1901-Test	If new NICs present (e.g. 100GE), add tests for these.
2n-skx Tests	Open	1901-Test	Drive parity of test coverage with 3n-skx, focusing on non-tunnel encapsulations.
AVF Driver Tests	Open	1901-Test	Drive parity of test coverage with DPDK for all baseline and scale tests.
Soak Tests	Open	1901-Framework	Productize soak performamce tests for extended test duration and throughput discovery at given PLR.
VPP_Device Xeon	Open	1901-Test	Execute on migrating VIRL tests to VPP_Device Container based functional VPP device tests running on 1n-skx.
VPP_Device Arm	Open	1901-Framework	Container based functional VPP device tests framework for 1n-arm testbeds.
VPP_Device Arm	Open	1901-test	Execute on migrating VIRL tests to VPP_Device Container based functional VPP device tests running on 1n-arm.
VPP_Device Atom	Open	1901-Framework	Container based functional VPP device tests framework for 1n-atom testbeds.
VPP_Device Atom	Open	1901-test	Execute on migrating VIRL tests to VPP_Device Container based functional VPP device tests running on 1n-atom.
VPP_Path	Open	1901-Framework	Continuing migration of CSIT VIRL tests to VPP-make_test VPP integration tests for functional acceptance of VPP feature path(s) driven by use case(s). See P1 and P2 markup in CSIT_VIRL migration progress.
Per VPP Patch Performance Checks	Open	1901-Framework	Per VPP patch vs. parent performance tests, anomaly detection, voting (-1/0/+1). Automated trigger subject to available physical testbed processing capacity.
CSIT PAPI Support	Open	1901-Framework	Implementation of PAPI L1 KWs in CSIT. Required for migraing away from VAT.
Clock cycles per VPP node into CSIT-PAL	Open	1901-PAL	Use the new VPP stats infra available via PAPI to retrieve runtime counters instead of using "show run". Blocked by no PAPI support in FD.io CSIT.
2n-dnv Environment	Open	1901-Framework	Onboard 2n-dnv (3n-dnv?) testbeds in LFN FD.io hosted lab.
2n-dnv Tests	Open	1901-Test	Port existing 2n-skx tests to 2n-dnv environment.
2n-arm Environment	Open	1901-Framework	Onboard 2n-arm (3n-arm?) testbeds in LFN FD.io hosted lab.
2n-arm Tests	Open	1901-Test	Port existing 2n-skx tests to 2n-arm environment.

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 greatest QEMU etc; iii) Push vpp-dev to Ubuntu 18.04.
Arm testbeds	Introduce Arm performance tests.
Atom testbeds	Introduce Atom performance tests.
Better vhost, memif coverage	Make CSIT produce more complete test data for scaled-out Vhost-user/VM and Memif/Container: i) Complete same packet paths and topologies for a low number of VMs and Containers, then scale-up VM and Container numbers; ii) See if we can isolate the actual cost of Vhostuser-virtio and Memif-Memif virtual interfaces based on the test and system telemetry.
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. Currently postponed, as the algorithm detects performance changes not related to VPP code. 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 experience vs. ordinary binary search: i) New POC for extended soak test for validating NDR (zero packet-loss-ratio PLR) and(?) PDR (non-zero PLR).
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-18.07 results data.
