traffic: Configurable traffic details
Traffic generated by traffic generator is based on default values and their modifications specific to particular testing scenario. Traffic default values were defined inside VSPERF code and it was not possible to change them. This patch introduces new TRAFFIC dictionary inside 03_traffic.conf. Thus user can modify any of TRAFFIC values either in configuration file or by CLI or by 'Parameters' section of testcase definition. Following CLI options were obsoleted by this patch: 'bidirectional', 'traffic_type', 'iload', 'multistream', 'stream_type' and 'pre-installed_flows' Following CLI option was renamed to be consistent with other options: 'tunnel_type' => 'TUNNEL_TYPE' Following sections of testcase definition were obsoleted: "Traffic Type", "biDirectional", "MultiStream", "Stream Type", "Pre-installed Flows", "Flow Type" and "iLoad" New TRAFFIC dictionary should be used instead of old CLI options and old testcase definition sections. Testcase definitons, yardstick sample testcases and documentation were updated to reflect configuration changes.

"trafficgen-pause" - execute vSwitch and VNF but wait before traffic transmission
In case, that VSPERF is executed in "trafficgen" mode, then configuration
-of traffic generator should be configured through ``--test-params`` option.
-Supported CLI options useful for traffic generator configuration are:
-
-.. code-block:: console
-
- 'traffic_type' - One of the supported traffic types. E.g.
- rfc2544_throughput,
- rfc2544_back2back or rfc2544_continuous
- Default value is "rfc2544_throughput".
- 'bidirectional' - Specifies if generated traffic will be full-duplex (true)
- or half-duplex (false)
- Default value is "false".
- 'iload' - Defines desired percentage of frame rate used during
- continuous stream tests.
- Default value is 100.
- 'multistream' - Defines number of flows simulated by traffic generator.
- Value 0 disables MultiStream feature
- Default value is 0.
- 'stream_type' - Stream Type is an extension of the "MultiStream" feature.
- If MultiStream is disabled, then Stream Type will be
- ignored. Stream Type defines ISO OSI network layer used
- for simulation of multiple streams.
- Default value is "L4".
+of traffic generator can be modified through ``TRAFFIC`` dictionary passed to the
+``--test-params`` option. It is not needed to specify all values of ``TRAFFIC``
+dictionary. It is sufficient to specify only values, which should be changed.
+Detailed description of ``TRAFFIC`` dictionary can be found at
+`Configuration of TRAFFIC dictionary
+<http://artifacts.opnfv.org/vswitchperf/docs/index.html#configuration-of-traffic-dictionary>`__
Example of execution of VSPERF in "trafficgen" mode:
.. code-block:: console
$ ./vsperf -m trafficgen --trafficgen IxNet --conf-file vsperf.conf \
- --test-params "traffic_type=rfc2544_continuous;bidirectional=True;iload=60"
+ --test-params "TRAFFIC={'traffic_type':'rfc2544_continuous','bidir':'False','framerate':60}"
