VIRL runs on physical baremetal servers hosted by LF FD.io project. +Based on the packet path through server SUTs, one logical topology type +is used for DMM DUT data plane testing: + +#. NIC-to-NIC switching topologies. + +NIC-to-NIC Switching +~~~~~~~~~~~~~~~~~~~~ + +The simplest logical topology for software data plane application like +DMM is NIC-to-NIC switching. Tested topologies for the 3-Node +testbed is shown in the figure below. + +.. only:: latex + + .. raw:: latex + + \begin{figure}[H] + \centering + \graphicspath{{../_tmp/src/vpp_performance_tests/}} + \includegraphics[width=0.90\textwidth]{logical-3n-nic2nic} + \label{fig:logical-3n-nic2nic} + \end{figure} + +.. only:: html + + .. figure:: ../vpp_performance_tests/logical-3n-nic2nic.svg + :alt: logical-3n-nic2nic + :align: center + +SUT1 and SUT2 are two VMs (Ubuntu), TG +is a Traffic Generator (TG, another Ubuntu VM). SUTs run sample server-client +application using the DMM libs in Linux user-mode as a Device Under Test (DUT) +within the VM. Currently TG node is not being used in DMM-CSIT. Logical +connectivity between SUTs is provided using virtual NICs using VMs' virtio +driver. + +Virtual testbeds are created on-demand whenever a verification job is started +(e.g. triggered by the gerrit patch submission) and destroyed upon completion +of all functional tests. Each node is a Virtual Machine and each connection +that is drawn on the diagram is available for use in any test case. During the +test execution, all nodes are reachable through the Management network connected +to every node via dedicated virtual NICs and virtual links (not shown above +for clarity). + +DMM Functional Tests Coverage +----------------------------- + +Following DMM functional test areas are covered in the |csit-release| with +results listed in this report: + +- **DMM basic testcase** - DMM has only one test case right now. + The testcase demonstrates single server[DUT1] and single client[DUT2] scenario + using DMM framework and kernel tcp/ip stack. + + - Test case count: 1 + +Total 1 DMM functional test in the |csit-release|. |
