Virtual Topologies
------------------
-CSIT NSH_SFC 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 thru server SUTs, one logical
-topology type is used for VPP DUT data plane testing:

-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 NSH_SFC 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).

-NSH_SFC Functional Tests Coverage
----------------------------------
-
-Following NSH_SFC functional test areas are covered in the |csit-release| with
-results listed in this report:
-
-- **NSH SFC Classifier** - TG sends some TCP packets to test NSH SFC
- Classifier functional. DUT1 will receive these packets from one NIC and
- loopback the VXLAN-GPE-NSH encapsulated packets to the TG from other NIC.
-
- - Test case count: 7
-
-- **NSH SFC Proxy Inbound** - TG sends some VXLAN-GPE-NSH encapsulated packets
- to test NSH SFC Proxy Inbound functional. DUT1 will receive these packets from
- one NIC and loopback the VXLAN encapsulated packets to the TG from other NIC.
-
- - Test case count: 6
-
-- **NSH SFC Proxy Outbound** - TG sends some VXLAN encapsulated packets to test
- NSH SFC Proxy Outbound functional. DUT1 will receive these packets from one
- NIC and loopback the VXLAN-GPE-NSH encapsulated packets to the TG from other
- NIC.
-
- - Test case count: 6
-
-- **NSH SFC Service Function Forward** - TG sends some VXLAN-GPE-NSH
- encapsulated packets to test NSH SFC Service Function Forward functional. DUT1
- will receive these packets from one NIC and swap the VXLAN-GPE-NSH header,
- after that DUT1 loopback the VXLAN-GPE-NSH encapsulated packtes to the TG from
- other NIC.
-
- - Test case count: 6
-
-Total 25 NSH SFC functional tests in the |csit-release|.
