-The minimal configuration file required must specify the PCI addresses of the 2 NIC ports to use.
-If OpenStack is used, the openrc_file property must be defined to point to a valid OpenStack rc file.
+Create a new file containing the minimal configuration for NFVbench, we can call it any name, for example "nfvbench.cfg" and paste the following yaml template in the file:
+
+.. code-block:: bash
+

+If OpenStack is not used, the openrc_file property can be removed.
-Here is an example of mimimal configuration using OpenStack where:
+If OpenStack is used, the openrc_file property must contain a valid container pathname of the OpenStack ``openrc`` file to connect to OpenStack using the OpenStack API.
+This file can be downloaded from the OpenStack Horizon dashboard (refer to the OpenStack documentation on how to
+retrieve the openrc file). This property must point to a valid pathname in the container (/tmp/nfvbench/openrc).
+We will map the host $HOME/nfvbench directory to the container /tmp/nfvbench directory and name the file "openrc".
+The file name viewed from the container will be "/tmp/nfvbench/openrc" (see container file pathname mapping in the next sections).
-- the openrc file is located on the host current directory which is mapped under /tmp/nfvbench in the container (this is achieved using -v $PWD:/tmp/nfvbench)
-- the 2 NIC ports to use for generating traffic have the PCI addresses "04:00.0" and "04:00.1"
+The PCI address of the 2 physical interfaces that will be used by the traffic generator must be configured.
+The PCI address can be obtained for example by using the "lspci" Linux command. For example:

-3. Start the Docker container
------------------------------
-As for any Docker container, you can execute NFVbench measurement sessions using a temporary container ("docker run" - which exits after each NFVbench run)
-or you can decide to run the NFVbench container in the background then execute one or more NFVbench measurement sessions on that container ("docker exec").
+.. warning::
+
+ You have to put quotes around the pci addresses as shown in the above example, otherwise TRex will read it wrong.
+ The other fields in the minimal configuration must be present and must have the same values as above.
-The former approach is simpler to manage (since each container is started and terminated after each command) but incurs a small delay at start time (several seconds).
-The second approach is more responsive as the delay is only incurred once when starting the container.
-We will take the second approach and start the NFVbench container in detached mode with the name "nfvbench" (this works with bash, prefix with "sudo" if you do not use the root login)
+3. Starting NFVbench in CLI mode
+--------------------------------
-First create a new working directory, and change the current working directory to there. A "nfvbench_ws" directory under your home directory is good place for that, and this is where the OpenStack RC file and NFVbench config file will sit.
+In this mode, the NFVbench code will reside in a container running in the background. This container will not run anything in the background.
+An alias is then used to invoke a new NFVbench benchmark run using docker exec.
+The $HOME/nfvbench directory on the host is mapped on the /tmp/nfvbench in the container to facilitate file sharing between the 2 environments.

-retrieve the openrc file). The file pathname in the container must be stored in the "openrc_file" property. If it is stored on the host in the current directory, its full pathname must start with /tmp/nfvbench (since the current directory is mapped to /tmp/nfvbench in the container).
+Edit the full_nfvbench.cfg file to only keep those properties that need to be modified (preserving the nesting).

+4. Start NFVbench in REST server mode
+-------------------------------------
+In this mode, the NFVbench REST server will run in the container.
+The $HOME/nfvbench directory on the host is mapped on the /tmp/nfvbench in the container to facilitate file sharing between the 2 environments.
+

+
+REST mode requires the same arguments as CLI mode and adds the following options:
++-------------------------------------------------------+-------------------------------------------------------+
+| Docker options | Description |
++=======================================================+=======================================================+
+| --net=host | use "host" docker networking mode |
+| | Other modes (such as NAT) could be used if required |
+| | with proper adjustment of the port to use for REST |
++-------------------------------------------------------+-------------------------------------------------------+
+| -e CONFIG_FILE="/tmp/nfvbench/nfvbench.cfg" | (optional) |
+| | specify the initial NFVbench config file to use. |
+| | defaults to none |
++-------------------------------------------------------+-------------------------------------------------------+
+| start_rest_server | to request a REST server to run in background in the |
+| | container |

+| | specify the IP address to listen to. |
+| | defaults to 127.0.0.1 |
++-------------------------------------------------------+-------------------------------------------------------+
+| -e PORT=7555 | (optional) |
+| | specify the port address to listen to. |
+| | defaults to 7555 |
++-------------------------------------------------------+-------------------------------------------------------+
+
+The initial configuration file is optional but is handy to define mandatory deployment parameters that are common to all subsequent REST requests.
+If this initial configuration file is not passed at container start time, it must be included in every REST request.

+
+Requesting an NFVbench benchmark run
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+To request a benchmark run, you must create a JSON document that describes the benchmark and send it to the NFVbench server in the body of a POST request.
+
+
+Examples of REST requests
+~~~~~~~~~~~~~~~~~~~~~~~~~
+In this example, we will use curl to interact with the NFVbench REST server.
+
+Query the NFVbench version:
-.. warning::
+.. code-block:: bash
- You have to put quotes around the pci addresses as shown in the above example, otherwise TRex will read it wrong.
+ [root@sjc04-pod3-mgmt ~]# curl -G http://127.0.0.1:7555/version
+ 3.1.1
-Alternatively, the full template with comments can be obtained using the --show-default-config option in yaml format:
+This is the JSON for a fixed rate run at 10,000pps bi-directional (or 5kpps in each direction) using the PVP packet path:
.. code-block:: bash
- nfvbench --show-default-config > my_nfvbench.cfg
+ {"rate": "10kpps"}
-Edit the nfvbench.cfg file to only keep those properties that need to be modified (preserving the nesting).
+This is the curl request to send this benchmark request to the NFVbench server:
-Make sure you have your nfvbench configuration file (my_nfvbench.cfg) and - if OpenStack is used - OpenStack RC file in your pre-created working directory.
+.. code-block:: bash
+ [root@sjc04-pod3-mgmt ~]# curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"rate": "10kpps"}' http://127.0.0.1:7555/start_run
+ {
+ "error_message": "nfvbench run still pending",
+ "status": "PENDING"
+ }
+ [root@sjc04-pod3-mgmt ~]#
-5. Run NFVbench
----------------
+This request will return immediately with status set to "PENDING" if the request was started successfully.
-To do a single run at 10,000pps bi-directional (or 5kpps in each direction) using the PVP packet path:
+The status can be polled until the run completes. Here the poll returns a "PENDING" status, indicating the run is still not completed:
.. code-block:: bash
- nfvbench -c /tmp/nfvbench/my_nfvbench.cfg --rate 10kpps
+ [root@sjc04-pod3-mgmt ~]# curl -G http://127.0.0.1:7555/status
+ {
+ "error_message": "nfvbench run still pending",
+ "status": "PENDING"
+ }
+ [root@sjc04-pod3-mgmt ~]#
-NFVbench options used:
+Finally, the status request returns a "OK" status along with the full results (truncated here):
-* ``-c /tmp/nfvbench/my_nfvbench.cfg`` : specify the config file to use (this must reflect the file path from inside the container)
-* ``--rate 10kpps`` : specify rate of packets for test for both directions using the kpps unit (thousands of packets per second)
+.. code-block:: bash
-This should produce a result similar to this (a simple run with the above options should take less than 5 minutes):
+ [root@sjc04-pod3-mgmt ~]# curl -G http://127.0.0.1:7555/status
+ {
+ "result": {
+ "benchmarks": {

NFVbench Server mode and NFVbench client API
============================================
-NFVbench can run as an HTTP server to:
-
-- optionally provide access to any arbitrary HTLM files (HTTP server function) - this is optional
-- service fully parameterized aynchronous run requests using the HTTP protocol (REST/json with polling)
-- service fully parameterized run requests with interval stats reporting using the WebSocket/SocketIO protocol.
-
-Start the NFVbench server
--------------------------
-To run in server mode, simply use the --server <http_root_path> and optionally the listen address to use (--host <ip>, default is 0.0.0.0) and listening port to use (--port <port>, default is 7555).
-
-
-If HTTP files are to be serviced, they must be stored right under the http root path.
-This root path must contain a static folder to hold static files (css, js) and a templates folder with at least an index.html file to hold the template of the index.html file to be used.
-This mode is convenient when you do not already have a WEB server hosting the UI front end.
-If HTTP files servicing is not needed (REST only or WebSocket/SocketIO mode), the root path can point to any dummy folder.
-
-Once started, the NFVbench server will be ready to service HTTP or WebSocket/SocketIO requests at the advertised URL.
-
-Example of NFVbench server start in a container:
-
-.. code-block:: bash
-
- # get to the container shell (assume the container name is "nfvbench")
- docker exec -it nfvbench bash
- # from the container shell start the NFVbench server in the background
- nfvbench -c /tmp/nfvbench/nfvbench.cfg --server /tmp &
- # exit container
- exit
