-To identify performance changes due to VPP code changes from v20.01.0 to
-v20.05.0, both have been tested in CSIT environment ver. 4 and compared
-against each other. All substantial progressions has been marked up with
-RCA analysis. See Current vs Previous Release and Known Issues.
-
-CSIT environment ver. 4 has been evaluated against the ver. 2 by
-benchmarking VPP v20.01.0 in both environment versions.

-Physical Testbeds
------------------
-
-FD.io CSIT performance tests are executed in physical testbeds hosted by
-:abbr:`LF (Linux Foundation)` for FD.io project. Two physical testbed
-topology types are used:
