-Tested Physical Topologies
---------------------------
-
-CSIT DPDK performance tests are executed on physical baremetal servers hosted
-by LF FD.io project. Testbed physical topology is shown in the figure below.

-SUT1 and SUT2 are two System Under Test servers (currently Cisco UCS C240,
-each with two Intel XEON CPUs), TG is a Traffic Generator (TG, currently
-another Cisco UCS C240, with two Intel XEON CPUs). SUTs run Testpmd/L3FWD SW
-application in Linux user-mode as a Device Under Test (DUT). TG runs TRex SW
-application as a packet Traffic Generator. Physical connectivity between SUTs
-and to TG is provided using direct links (no L2 switches) connecting different
-NIC models that need to be tested for performance. Currently installed and
-tested NIC models include:
-
-#. 2port10GE X520-DA2 Intel.
-#. 2port10GE X710 Intel.
-#. 2port10GE VIC1227 Cisco.
-#. 2port40GE VIC1385 Cisco.
-#. 2port40GE XL710 Intel.

-Performance Tests Coverage
---------------------------
-
-Performance tests are split into the two main categories:
-
-- Throughput discovery - discovery of packet forwarding rate using binary search
- in accordance with RFC2544.
-
- - NDR - discovery of Non Drop Rate packet throughput, at zero packet loss;
- followed by packet one-way latency measurements at 10%, 50% and 100% of
- discovered NDR throughput.
- - PDR - discovery of Partial Drop Rate, with specified non-zero packet loss
- currently set to 0.5%; followed by packet one-way latency measurements at
- 100% of discovered PDR throughput.
