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

-SUT1 and SUT2 are two VMs (Ubuntu or Centos, depending on the test suite), TG\r
-is a Traffic Generator (TG, another Ubuntu VM). SUTs run VPP SW application in\r
-Linux user-mode as a Device Under Test (DUT) within the VM. TG runs Scapy SW\r
-application as a packet Traffic Generator. Logical connectivity between SUTs\r
-and to TG is provided using virtual NICs using VMs' virtio driver.\r
-\r
-Virtual testbeds are created on-demand whenever a verification job is started\r
-(e.g. triggered by the gerrit patch submission) and destroyed upon completion\r
-of all functional tests. Each node is a Virtual Machine and each connection\r
-that is drawn on the diagram is available for use in any test case. During the\r
-test execution, all nodes are reachable thru the Management network connected\r
-to every node via dedicated virtual NICs and virtual links (not shown above\r
-for clarity).\r
-\r
-For the test cases that require DUT (VPP) to communicate with VM over the\r
-vhost-user interfaces, a nested VM is created on SUT1 and/or SUT2 for the\r
-duration of these particular test cases only. DUT (VPP) test topology with VM\r
-is shown in the figure below including the applicable packet flow thru the VM\r
-(marked in the figure with ``***``).\r
