+Tested Virtual Topologies
+-------------------------
+
+CSIT VPP functional tests are executed on virtualized topologies created using
+Virtual Internet Routing Lab (VIRL) simulation platform contributed by Cisco.
+VIRL runs on physical baremetal servers hosted by LF FD.io project. Majority
+of the tests are executed in the three node logical test topology - Traffic
+Generator (TG) node and two Systems Under Test (SUT) nodes connected in a
+loop. Some tests use two node logical test topology - TG node and SUT1 node.
+Both logical test topologies are shown in the figures below.
+
+::
+

+ | | TG | |

+ +-----------+
+
+SUT1 and SUT2 are two VMs (Ubuntu or Centos, depending on the test suite), TG
+is a Traffic Generator (TG, another Ubuntu VM). SUTs run VPP SW application in
+Linux user-mode as a Device Under Test (DUT) within the VM. TG runs Scapy SW
+application as a packet Traffic Generator. Logical connectivity between SUTs
+and to TG 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 thru the Management network connected
+to every node via dedicated virtual NICs and virtual links (not shown above
+for clarity).
+
+For the test cases that require DUT (VPP) to communicate with VM over the
+vhost-user interfaces, a nested VM is created on SUT1 and/or SUT2 for the
+duration of these particular test cases only. DUT (VPP) test topology with VM
+is shown in the figure below including the applicable packet flow thru the VM
+(marked in the figure with ``***``).

+Functional Tests Naming
+-----------------------
+
+CSIT |release| introduced a common structured naming convention for all
+performance and functional tests. This change was driven by substantially
+growing number and type of CSIT test cases. Firstly, the original practice did
+not always follow any strict naming convention. Secondly test names did not
+always clearly capture tested packet encapsulations, and the actual type or
+content of the tests. Thirdly HW configurations in terms of NICs, ports and
+their locality were not captured either. These were but few reasons that drove
+the decision to change and define a new more complete and stricter test naming
+convention, and to apply this to all existing and new test cases.
+
+The new naming should be intuitive for majority of the tests. The complete
+description of CSIT test naming convention is provided on `CSIT test naming
+page <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
+
+Here few illustrative examples of the new naming usage for functional test
+suites:
+
+#. **Physical port to physical port - a.k.a. NIC-to-NIC, Phy-to-Phy, P2P**
+
+ - *eth2p-ethip4-ip4base-func.robot* => 2 ports of Ethernet, IPv4 baseline
+ routed forwarding, functional tests.
+
+#. **Physical port to VM (or VM chain) to physical port - a.k.a. NIC2VM2NIC,
+ P2V2P, NIC2VMchain2NIC, P2V2V2P**
+
+ - *eth2p-ethip4vxlan-l2bdbasemaclrn-eth-2vhost-1vm-func.robot* => 2 ports of
+ Ethernet, IPv4 VXLAN Ethernet, L2 bridge-domain switching to/from two vhost
+ interfaces and one VM, functional tests.
