Virtual Topologies
------------------
-CSIT DMM functional tests are executed on virtualized topologies created using
-:abbr:`VIRL (Virtual Internet Routing Lab)` simulation platform contributed by
-Cisco. 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
-~~~~~~~~~~~~~~~~~~~~
-
-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.
+All tests are executed in three-node virtual test topology shown in the
+figure below.

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