Release Notes
=============
Changes in |csit-release|
-------------------------
#. VPP PERFORMANCE TESTS
- **Service density 2n-skx tests**: Added higher NF density tests with two
NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
used as a VNF payload similar to CNF tests.
- **Soak Tests**: Optimized performamce soak tests framework
code for extended time duration tests and throughput discovery
at given PLR and at give total test time e.g. minutes, hours,
days, weeks. See updated
:ref:`test_methodology` section for more details.
#. TEST FRAMEWORK
- **Qemu code refactor**: Complete code refactor of the key components of
QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
implementation of kernel-image-kvm based VM replacing the previously used
NestedVM images. Added ability to run VPP as a payload in VNF.
- **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to
PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components
of PAPI Executor and PAPI history.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
removal of redundant RF keywords.
- **Test suite generator**: Added capability to generate suites for
different NIC models as well as throughput search algorithm types. Uses
base tests suites as source.
- **TOX verification**: Added verifications for test suite generator.
#. PRESENTATION AND ANALYTICS LAYER
- **Graphs Layout Improvements**: Improved performance graphs layout
for better readibility and maintenance: test grouping, axis
labels, descriptions, other informative decoration.
..
#. MISCELLANEOUS
- **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
|csit-release| automated testing code.
Only graphs for Packet Throughput and Speedup Multi-core and not
for Packet Latency were published as there are no results for Packet
Latency available.
