+Versioning
+----------
+
+In order to determine any benchmark anomalies (progressions,
+regressions) between releases of a specific data-plane DUT application
+(e.g. VPP, DPDK), the DUT needs to be tested in the same test
+environment, to avoid test environment changes impacting the results and
+clouding the picture.
+
+In order to enable test system evolution, a mirror scheme is required to
+determine benchmarking anomalies between releases of specific test
+system like CSIT. This is achieved by testing the same DUT application
+version between releases of CSIT test system.
+
+CSIT test environment versioning scheme ensures integrity of all the
+test system components, including their HW revisions, compiled SW code
+versions and SW source code, within a specific CSIT version. Components
+included in the CSIT environment versioning include:
+
+- Server hosts hardware firmware and BIOS (motherboard, processsor, NIC(s), accelerator card(s)).
+- Server host Linux operating system versions.
+- Server host Linux configuration.
+- TRex Traffic Generator version, drivers and configuration.
+- CSIT framework code.
