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 documentation: + +1. **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. VPP application runs in + bare-metal host user-mode handling NICs. TRex is used as a traffic generator. +2. **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. +3. **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. +4. **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. +5. **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. +6. **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 Robot +Framework json output files produced by Linux Foundation FD.io Jenkins jobs +executed against {{< release_vpp >}} artifacts. + +FD.io CSIT system is developed using two main coding platforms: Robot +Framework and Python. {{< release_csit >}} source code for the executed test +suites is available in corresponding CSIT branch in the directory +`./tests/<name_of_the_test_suite>`. A local copy of CSIT source code +can be obtained by cloning CSIT git repository - `git clone +https://gerrit.fd.io/r/csit`. |
