+
+Virtual Topologies
+------------------
+
+CSIT VPP Device tests are executed in Physical containerized topologies
+created on demand using set of scripts hosted and developed under CSIT
+repository. It runs on physical baremetal servers hosted by LF FD.io project.
+Based on the packet path thru SUT Containers, two distinct logical topology
+types are used for VPP DUT data plane testing:
+
+#. vfNIC-to-vfNIC switching topologies.
+#. Nested-VM service switching topologies. (Planned to be added in rls1901)
+
+vfNIC-to-vfNIC Switching
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The simplest physical topology for software data plane application like
+VPP is vfNIC-to-vfNIC switching. Tested virtual topologies for 2-Node testbeds
+are shown in figures below.

+SUT1 is Docker Container (running Ubuntu, depending on the test suite), TG is
+a Traffic Generator (running Ubuntu Container). SUTs run VPP
+SW application in Linux user-mode as a Device Under Test (DUT) within
+the container. TG runs Scapy SW application as a packet Traffic Generator.
+Network connectivity between SUTs and to TG is provided using virtual function
+of physical NICs.
+
+Virtual topologies 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 container running on
+physical server. During the test execution, all nodes are reachable thru
+the Management (not shown above for clarity).

+Functional Tests Coverage
+-------------------------
+
+|csit-release| includes following VPP functionality tested in virtual VM
+environment:
+
++-----------------------+----------------------------------------------+
+| Functionality         |  Description                                 |
++=======================+==============================================+
+| IPv4                  | ICMPv4.                                      |
++-----------------------+----------------------------------------------+
+| IPv6                  | ICMPv6.                                      |
++-----------------------+----------------------------------------------+
+
+Tests Naming
+------------
+
+|csit-release| follows a common structured naming convention for all
+performance and system functional tests, introduced in CSIT-17.01.
+
+The naming should be intuitive for majority of the tests. Complete
+description of CSIT test naming convention is provided on
+:ref:`csit_test_naming`.
