+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.
