-Test Scenarios
-==============
-
-FD.io |csit-release| report includes multiple test scenarios of VPP
-centric applications, topologies and use cases. In addition it also
-covers baseline tests of DPDK sample applications. Tests are executed in
-physical (performance tests) and virtual environments (functional
-tests).
-
-Brief overview of test scenarios covered in this report:
-
-#. **VPP Performance**: VPP performance tests are executed in physical
- FD.io testbeds, focusing on VPP network data plane performance in
- NIC-to-NIC switching topologies. Tested across Intel Cascadelake
- and Skylake servers, ARM, Denverton, range of NICs (10GE, 25GE, 40GE, 100GE)
- and multi-thread/multi-core configurations. VPP application runs in
- bare-metal host user-mode handling NICs. TRex is used as a traffic generator.
-
-#. **VPP Vhostuser Performance with KVM VMs**: VPP VM service switching
- performance tests using vhostuser virtual interface for
- interconnecting multiple NF-in-VM instances. VPP vswitch
- instance runs in bare-metal user-mode handling NICs and connecting
- over vhost-user interfaces to VM instances each running VPP with virtio
- virtual interfaces. Similarly to VPP Performance, tests are run across a
- range of configurations. TRex is used as a traffic generator.
-
-#. **VPP Memif Performance with LXC and Docker Containers**: VPP
- Container service switching performance tests using memif virtual
- interface for interconnecting multiple VPP-in-container instances.
- VPP vswitch instance runs in bare-metal user-mode handling NICs and
- connecting over memif (Slave side) interfaces to more instances of
- VPP running in LXC or in Docker Containers, both with memif
- interfaces (Master side). Similarly to VPP Performance, tests are
- run across a range of configurations. TRex is used as a traffic
- generator.
-
-#. **DPDK Performance**: VPP uses DPDK to drive the NICs and physical
- interfaces. DPDK performance tests are used as a baseline to
- profile performance of the DPDK sub-system. Two DPDK applications
- are tested: Testpmd and L3fwd. DPDK tests are executed in the same
- testing environment as VPP tests. DPDK Testpmd and L3fwd
- applications run in host user-mode. TRex is used as a traffic
- generator.
-
-#. **T-Rex Performance**: T-Rex perfomance tests are executed in physical
- FD.io testbeds, focusing on T-Rex data plane performance in NIC-to-NIC
- loopback topologies. Tested across Intel Skylake servers, range of NICs
- (10GE) and selected traffic profiles. 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 both network data plane and in-line control plane. Tests
- cover vNIC-to-vNIC vNIC-to-nestedVM-to-vNIC forwarding topologies.
- Scapy is used as a traffic generator.

-All CSIT test data included in this report is auto-
-generated from :abbr:`RF (Robot Framework)` :file:`output.xml` files
-produced by :abbr:`LF (Linux Foundation)` FD.io Jenkins jobs executed
-against |vpp-release| artifacts. References are provided to the
-original FD.io Jenkins job results and all archived source files.
-
-FD.io CSIT system is developed using two main coding platforms: :abbr:`RF (Robot
-Framework)` and Python. |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`.
