2018-04-11ixia: Bugfixing and burst type enhancementMartin Klozik1-10/+15
A support for proper reporting of "Burst" traffic type was added. Several bugs were fixed: * RFC2544 Throughput - end of search condition was moved to avoid situation, that another iteration is executed but its results dropped * RFC2544 Throughput - pause after each iteration was added to ensure that all frames are cleared from buffers; It improves stability of results. Also "received" values are no longer higher then "sent" values. * VSPERF will report also the number of sent and received frames * VSPERF will correctly process send and received values - they were switched on several places JIRA: VSPERF-149 JIRA: VSPERF-562 Change-Id: I8a5caa6385a1ef86aa4bf4511d2753100ed0ab14 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Sridhar Rao <sridhar.rao@spirent.com> Reviewed-by: Richard Elias <richardx.elias@intel.com>

2018-03-26scapy: Fix conflict of scapy librariesMartin Klozik2-4/+23
T-Rex requires a modified version of SCAPY library for python3 to function properly. It doesn't work with vanilla version of scapy-python3 module, which is installed within vsperf environment by pip for Xena. Currently vanilla scapy is imported by Xena and enforced to T-Rex too, which causes following issues: * missing implementation of Dot1AD causes failures * broken multistream feature in T-Rex VSPERF loads all Traffic Generator classes and thus all imports performed at module level are performed. The solution would be to import SCAPY module by Xena only in case, that Xena traffic generator is really used. Please see JIRA for additional information.

2017-01-23xena_cont_learning: Adds learning preemption to continuous trafficChristian Trautman2-0/+18
Adds a configurable learning preemptive option when running xena continuous traffic tests. This resolves a missing packet or two when running OVS tests at flow rates that should not drop packets.

2017-01-23xena_cont_accuracy_fix: Xena continuous traffic accuracy fixesChristian Trautman1-7/+11
Second patch to help improve Xena continuous traffic accuracy. Increases delay before gathering statistics to allow packets in flight to be received. Changes bps and fps to be calculated based on total bytes and packets received versus capturing the data while port is transmitting from active statistics. Sets time limit on ports based on duration.

2017-01-16traffic: Configurable traffic detailsMartin Klozik8-145/+27
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.

2017-01-05pkt_gen: STC - Handle Results DB file synchronization failures.Sridhar K. N. Rao2-4/+14
If the downloading of results-database file fails, the CSV file and corresponding results are not generated - eventhough the test was successful. This small patch handles such cases. Updated the logging to be more explicit. JIRA: VSPERF-435 Change-Id: I14bf519fbca2ea362777e29920bc1759494965e0 Signed-off-by: Sridhar K. N. Rao <sridhar.rao@spirent.com>
