  28 SUT1 and SUT2 are two System Under Test servers (Cisco UCS C240, each with two\r
  29 Intel XEON CPUs), TG is a Traffic Generator (TG, another Cisco UCS C240, with\r
  30 two Intel XEON CPUs). SUTs run VPP SW application in Linux user-mode as a\r
  31 Device Under Test (DUT). TG runs TRex SW application as a packet Traffic\r
  32 Generator. Physical connectivity between SUTs and to TG is provided using\r
  33 different NIC models that need to be tested for performance. Currently\r
  34 installed and tested NIC models include:\r
  35 \r
  36 #. 2port10GE X520-DA2 Intel.\r
  37 #. 2port10GE X710 Intel.\r
  38 #. 2port10GE VIC1227 Cisco.\r

  42 Detailed LF FD.io test bed specification and topology is described on `CSIT LF\r
  43 testbed wiki page <https://wiki.fd.io/view/CSIT/CSIT_LF_testbed>`_.\r
  44 \r
  45 For test cases that require DUT (VPP) to communicate with VM over vhost-user\r
  46 interfaces, a VM is created on SUT1 and SUT2. DUT (VPP) test topology with VM\r
  47 is shown in the figure below including applicable packet flow thru the VM\r

  72 Note that for VM tests, packets are switched by DUT (VPP) twice, hence the\r
  73 throughput rates measured by TG must be multiplied by two to represent the\r
  74 actual DUT packet forwarding rate.\r
  75 \r
  76 VPP Performance Tests Overview\r
  77 ------------------------------\r
  78 \r
  79 Performance tests are split into two main categories:\r
  80 \r
  81 - Throughput discovery - discovery of packet forwarding rate using binary search\r
  82   in accordance to RFC2544.\r
  83 \r
  84   - NDR - discovery of Non Drop Rate, zero packet loss.\r
  85   - PDR - discovery of Partial Drop Rate, with specified non-zero packet loss.\r
  86 \r
  87 - Throughput verification - verification of packet forwarding rate against\r
  88   previously discovered throughput rate. These tests are currently done against\r
  89   0.9 of reference NDR, with reference rates updated periodically.\r
