All substantial progressions and +regressions have been marked up with RCA analysis. See +:ref:`vpp_throughput_comparisons` and :ref:`vpp_known_issues`. + +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: + +- **3-Node Topology**: Consisting of two servers acting as SUTs + (Systems Under Test) and one server as TG (Traffic Generator), all + connected in ring topology. +- **2-Node Topology**: Consisting of one server acting as SUTs and one + server as TG both connected in ring topology. + +Tested SUT servers are based on a range of processors.
