For test cases that require DUT (VPP) to communicate with
-VirtualMachines (VMs) / LinuxContainers (LXCs) over vhost-user/memif
-interfaces, N of VM/LXC instances are created on SUT1 and SUT2. For N=1
-DUT forwards packets between vhost/memif and physical interfaces. For

Hence the external throughput rates measured by TG and listed in this
report must be multiplied by (N+1) to represent the actual DUT aggregate
packet forwarding rate.

-----------------------------------------

+`TRex traffic generator <https://wiki.fd.io/view/TRex>`_ is used for all
CSIT performance tests. TRex stateless mode is used to measure NDR and PDR
throughputs using binary search (NDR and PDR discovery tests) and for quick
checks of DUT performance against the reference NDRs (NDR check tests) for
- TRex is started in the background mode
::
- $ sh -c 'cd /opt/trex-core-2.25/scripts/ && sudo nohup ./t-rex-64 -i -c 7 --iom 0 > /dev/null 2>&1 &' > /dev/null

- There are traffic streams dynamically prepared for each test, based on traffic
profiles. The traffic is sent and the statistics obtained using
If measurement of latency is requested, two more packet streams are created (one
for each direction) with TRex flow_stats parameter set to STLFlowLatencyStats. In
that case, returned statistics will also include min/avg/max latency values.

+Methodology: TCP/IP tests with WRK tool
+---------------------------------------
+
+`WRK HTTP benchmarking tool <https://github.com/wg/wrk>`_ is used for
+experimental TCP/IP and HTTP tests of VPP TCP/IP stack and built-in
+static HTTP server. WRK has been chosen as it is capable of generating
+significant TCP/IP and HTTP loads by scaling number of threads across
+multi-core processors.
+
+This in turn enables quite high scale benchmarking of the main TCP/IP
+and HTTP service including HTTP TCP/IP Connections-Per-Second (CPS),
+HTTP Requests-Per-Second and HTTP Bandwidth Throughput.
+
+The initial tests are designed as follows:
+
+- HTTP and TCP/IP Connections-Per-Second (CPS)
+
+ - WRK configured to use 8 threads across 8 cores, 1 thread per core.
+ - Maximum of 50 concurrent connections across all WRK threads.
+ - Timeout for server responses set to 5 seconds.
+ - Test duration is 30 seconds.
+ - Expected HTTP test sequence:
+
+ - Single HTTP GET Request sent per open connection.
+ - Connection close after valid HTTP reply.
+ - Resulting flow sequence - 8 packets: >S,<S-A,>A,>Req,<Rep,>F,<F,> A.
+
+- HTTP Requests-Per-Second
+
+ - WRK configured to use 8 threads across 8 cores, 1 thread per core.
+ - Maximum of 50 concurrent connections across all WRK threads.
+ - Timeout for server responses set to 5 seconds.
+ - Test duration is 30 seconds.
+ - Expected HTTP test sequence:
+
+ - Multiple HTTP GET Requests sent in sequence per open connection.
+ - Connection close after set test duration time.
+ - Resulting flow sequence: >S,<S-A,>A,>Req[1],<Rep[1],..,>Req[n],<Rep[n],>F,<F,>A.
