Encourage the community to contribute and close the feature gaps. + • † No Vendor/Proprietary Workloads + +SampleVNF supports installation directly in Ubuntu. The installation procedure +are detailed in the sections below. + +The steps needed to run SampleVNF are: +1. Install and Build SampleVNF. +2. deploy the VNF on the target and modify the config based on the + Network under test +3. Run the traffic generator to generate the traffic. + +Prerequisites +------------- + +Supported Test setup: +-------------------- +The device under test (DUT) consists of a system following; + * A single or dual processor and PCH chip, except for System on Chip (SoC) cases + * DRAM memory size and frequency (normally single DIMM per channel) + * Specific Intel Network Interface Cards (NICs) + * BIOS settings noting those that updated from the basic settings + * DPDK build configuration settings, and commands used for tests +Connected to the DUT is an IXIA* or Software Traffic generator like pktgen or TRex, +simulation platform to generate packet traffic to the DUT ports and +determine the throughput/latency at the tester side. + +Below are the supported/tested (:term `VNF`) deployment type. +.. image:: images/deploy_type.png + :width: 800px + :alt: SampleVNF supported topology + +Hardware & Software Ingredients +------------------------------- +.. code-block:: console + +-----------+------------------+ + | Item | Description | + +-----------+------------------+ + | Memory | Min 20GB | + +-----------+------------------+ + | NICs | 2 x 10G | + +-----------+------------------+ + | OS | Ubuntu 16.04 LTS | + +-----------+------------------+ + | kernel | 4.4.0-34-generic| + +-----------+------------------+ + |DPD | 17.02 | + +-----------+------------------+ + + Boot and BIOS settings + +------------------+---------------------------------------------------+ + | Boot settings | default_hugepagesz=1G hugepagesz=1G hugepages=16 | + | | hugepagesz=2M hugepages=2048 isolcpus=1-11,22-33 | + | | nohz_full=1-11,22-33 rcu_nocbs=1-11,22-33 | + | | Note: nohz_full and rcu_nocbs is to disable Linux*| + | | kernel interrupts, and it’s import | + +------------------+---------------------------------------------------+ + |BIOS | CPU Power and Performance Policy <Performance> | + | | CPU C-state Disabled | + | | CPU P-state Disabled | + | | Enhanced Intel® Speedstep® Tech Disabled | + | | Hyper-Threading Technology (If supported) Enable | + | | Virtualization Techology Enable | + | | Coherency Enable | + | | Turbo Boost Disabled | + +------------------+---------------------------------------------------+ + +Network Topology for testing VNFs +--------------------------------- +The ethernet cables should be connected between traffic generator and the VNF server (BM, +SRIOV or OVS) setup based on the test profile. + +The connectivity could be +1.
