Example invocation:
$ yardstick samples/ping-task.yaml
+
+ Servers are the same as VMs (Nova call them servers in the API)
+
+ Many tests use a client/server architecture. A test client is configured
+ to use a specific test server e.g. using an IP address. This is true for
+ example iperf. In some cases the test server is included in the kernel
+ (ping, pktgen) and no additional software is needed on the server. In other
+ cases (iperf) a server process needs to be installed and started
+
+ One server is required to host the test client program (such as ping or
+ iperf). In the task file this server is called host.
+
+ A server can be the _target_ of a test client (think ping destination
+ argument). A target server is optional but needed in most test scenarios.
+ In the task file this server is called target. This is probably the same
+ as DUT in existing terminology.
+
+ Existing terminology:
+ https://www.ietf.org/rfc/rfc1242.txt (throughput/latency)
+ https://www.ietf.org/rfc/rfc2285.txt (DUT/SUT)
+
+ New terminology:
+ NFV TST
