Testbed physical topology is shown in the figure below. - -:: - - +------------------------+ +------------------------+ - | | | | - | +------------------+ | | +------------------+ | - | | | | | | | | - | | <-----------------> | | - | | DUT1 | | | | DUT2 | | - | +--^---------------+ | | +---------------^--+ | - | | | | | | - | | SUT1 | | SUT2 | | - +------------------------+ +------------------^-----+ - | | - | | - | +-----------+ | - | | | | - +------------------> TG <------------------+ - | | - +-----------+ - -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 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. - -Detailed LF FD.io test bed specification and topology is described in -`wiki CSIT LF testbed <https://wiki.fd.io/view/CSIT/CSIT_LF_testbed>`_. - -Testing Summary ---------------- - -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. - -- Throughput verification - verification of packet forwarding rate against - previously discovered NDR throughput. These tests are currently done against - 0.9 of reference NDR, with reference rates updated periodically. - -CSIT |release| includes following performance test suites, listed per NIC type: - -- 2port10GE X520-DA2 Intel - - - **L2IntLoop** - L2 Interface Loop forwarding any Ethernet frames between - two Interfaces. - -Execution of performance tests takes time, especially the throughput discovery -tests. Due to limited HW testbed resources available within FD.io labs hosted -by Linux Foundation, the number of tests for NICs other than X520 (a.k.a. -Niantic) has been limited to few baseline tests. Over time we expect the HW -testbed resources to grow, and will be adding complete set of performance -tests for all models of hardware to be executed regularly and(or) -continuously. |
