General Notes
=============
All CSIT test results listed in this report are sourced and auto-generated
from :file:`output.xml` :abbr:`RF (Robot Framework)` files resulting from
:abbr:`LF (Linux Foundation)` FD.io Jenkins jobs execution against |vpp-release|
release artifacts. References are provided to the original :abbr:`LF (Linux
Foundation)` FD.io Jenkins job results. Additional references are provided to
the :abbr:`RF (Robot Framework)` result files that got archived in FD.io nexus
online storage system.
FD.io CSIT project currently covers multiple FD.io system and sub-system
testing areas and this is reflected in this report, where each testing area
is listed separately, as follows:
#. **VPP - Performance** - VPP benchmarking tests are executed in physical
FD.io testbeds, focusing on VPP network data plane performance at this stage,
both for Phy-to-Phy (NIC-to-NIC) and Phy-to-VM-to-Phy (NIC-to-VM-to-NIC)
forwarding topologies. Tested across a range of NICs, 10GE, 25GE and 40GE
interfaces, range of multi-thread and multi-core configurations. VPP
application runs in host user-mode. TRex is used as a traffic generator.
#. **LXC and Docker Containers VPP memif - Performance** - VPP memif
virtual interface tests interconnect multiple VPP instances running in
containers. VPP vswitch instance runs in bare-metal user-mode
handling Intel x520 NIC 10GbE, Intel x710 NIC 10GbE, Intel xl710 NIC 40GbE
interfaces and connecting over memif (Slave side) virtual interfaces to more
instances of VPP running in LXC or in Docker Containers, both with memif
virtual interfaces (Master side). Tested across a range of multi-thread and
multi-core configurations. TRex is used as a traffic generator.
#. **Container Topologies Orchestrated by K8s - Performance** - CSIT Container
topologies connected over the memif virtual interface (shared memory
interface). For these tests VPP vswitch instance runs in a Docker Container
handling Intel x520 NIC 10GbE, Intel x710 NIC 10GbE interfaces and connecting
over memif virtual interfaces to more instances of VPP running in Docker
Containers with memif virtual interfaces. All containers are
orchestrated by Kubernetes, with `Ligato <https://github.com/ligato>`_ for
container networking. TRex is used as a traffic generator.
#. **DPDK Performance** - VPP is using DPDK code to control and drive
the NICs and physical interfaces. Tests are used as a baseline to
profile performance of the DPDK sub-system. DPDK tests are executed in
physical FD.io testbeds, focusing on Testpmd/L3FWD data plane performance for
Phy-to-Phy (NIC-to-NIC). Tested across a range of NICs, 10GE, 25GE and 40GE
interfaces, range of multi-thread and multi-core configurations.
Testpmd/L3FWD application runs in host user-mode. TRex is used as a traffic
generator.
#. **VPP Functional** - VPP functional tests are executed in virtual
FD.io testbeds focusing on VPP packet processing functionality, including
network data plane and in -line control plane. Tests cover vNIC-to-vNIC
vNIC-to-VM-to-vNIC forwarding topologies. Scapy is used as a traffic
generator.
#. **Honeycomb Functional** - Honeycomb functional tests are executed in
virtual FD.io testbeds, focusing on Honeycomb management and programming
functionality of VPP. Tests cover a range of CRUD operations executed
against VPP.
#. **NSH_SFC Functional** - NSH_SFC functional tests are executed in
virtual FD.io testbeds focusing on NSH_SFC of VPP. Tests cover a range of
CRUD operations executed against VPP.
In addition to above, |csit-release| report does also include VPP unit test
results. VPP unit tests are developed within the FD.io VPP project and as they
complement CSIT system functional tests, they are provided mainly as a reference
and to provide a more complete view of automated testing executed against
|vpp-release|.
FD.io CSIT system is developed using two main coding platforms :abbr:`RF (Robot
Framework)` and Python2.7. |csit-release| source code for the executed test
suites is available in CSIT branch |release| in the directory
:file:`./tests/<name_of_the_test_suite>`. A local copy of CSIT source code
can be obtained by cloning CSIT git repository - :command:`git clone
https://gerrit.fd.io/r/csit`.
