7 CSIT DMM functional tests are executed in VM-based virtual topologies
8 created on demand using :abbr:`VIRL (Virtual Internet Routing Lab)`
9 simulation platform contributed by Cisco. VIRL runs on physical
10 baremetal servers hosted by LF FD.io project.
12 All tests are executed in three-node virtual test topology shown in the

32 SUT1 and SUT2 are two VMs (running Ubuntu), TG is a Traffic Generator VM
33 (running Ubuntu). SUTs run
34 sample server-client application using the DMM libraries in Linux user-
35 mode as a Device Under Test (DUT) within the VM. Currently TG node is
36 not being used in DMM-CSIT. Network connectivity between SUTs and to TG
37 is provided using virtual NICs and VMs' virtio drivers.
39 Functional Tests Coverage

42 |csit-release| includes following DMM functionality tested in virtual VM
45 +-----------------------+----------------------------------------------+
46 | Functionality | Description |
47 +=======================+==============================================+
48 | DMM basic operation | DMM has only one test case right now. The |
49 | | testcase demonstrates single server[DUT1] |
50 | | and single client[DUT2] scenario using DMM |
51 | | framework and kernel tcp/ip stack. |
