2022-05-03feat(astf): Support framesizes for ASTFVratko Polak1-8/+11
- No support for IMIX. + Fix a bad bug in padding (most ASTF profiles had wrong frame sizes). + Fix a big typo in TCP PPS profiles (s->c was not data, just RST). + Control transaction size via ASTF_N_DATA_FRAMES env variable. - Default value 5 leads to transactions smaller than before. + It ensures transaction is one burst (per direction) even for jumbo. + Edit autogen to set supported frame sizes based on suite id. + Both TCP and UDP use the same values: + 64B for CPS (exact for UDP, nominal for TCP). + 100B, 1518B and 9000B for TPUT and PPS. - TCP TPUT achievable minimum is 70B. + Used 100B to leave room for possible IPv6 ASTF tests. + Separate function for code reused by vpp and trex tests. - I do not really like the new "copy and edit" approach added here. + But it is a quick edit, better autogen refactor is low priority. + Consider both established and transitory sessions as valid. - Mostly for compatibility with 2202 behavior and to avoid ramp-ups. - Assuming both session states have similar enough VPP CPU overhead. + Added a TODO to investigate and maybe reconsider later. + Update the state timeout value to 240s. + That is the default for TCP (for transitory state). - UDP could keep using 300s. + But I prefer UDP and TCP to behave as similarly as possible. + Use TRex tunables to get the exact frame size (for data packets). - It is not clear why the recipe for MSS has to be this complicated. + Move code away from profile init, as frame size is not known there. + Change internal profile API, so values related to MSS are passed. + Lower ramp-up rate for TCP TPUT tests. + Because without lower rate, jumbo fails on packet loss in ramp-up. + UDP TPUT ramp-up rate also lowered (just to keep suites more similar). + Distinguish one-direction and aggregated average frame size. + Update keyword documentation where the distiction matters. + One-direction is needed for turning bandwidth limit to TPS limit. + Aggregated is needed for correct NDRPDR bandwidth result value. - TCP TPUT will always be few percent below bidirectional maximum. + That is unavoidable, as one direction sends more control packets. + Add runtime consistency checks so future refactors are safer. + Fail if padding requested would be negative. + Fail if suite claims unexpected values for packets per transaction. + Edit the 4 types of ASTF profiles to keep them similar to each other. + Move UDP TPUT limit value from a field back to direct argument. + Stop pretending first UDP packet is not data. + Apply small improvements where convenient. + Replace "aggregate" with "aggregated" where possible. + To lower probability of any future typos in variable names. + Avoid calling Set Numeric Frame Sizes twice. + Code formatting, keyword documentation, code comments, ... + Add TODOs for less important code quality improvements. - Postpone updating of methodology pages to a subsequent change.

2021-09-29MLRsearch: Increase timeout to 20 minutesVratko Polak1-1/+1
There are sporadic failures due to timeout. An earlier edit changed how the timeout is applied (now it is for the whole search, previously it was for final phase only) so failures are not unexpected. Increasing timeout value from 12 minutes to 20 minutes (both for NDRPDR and for NDR part of RECONF) as the frequency shows it will not prolong runs much. The timeout is increased both in Robot call site and in Python keyword default argument. Change-Id: I3f07125ba9eeb90ce5819b1450044441b8b3977a Signed-off-by: Vratko Polak <vrpolak@cisco.com>

+ PPS limit for AWS set to 1.2 Mpps. + The logic is very similar to that one in ASTF driver. + This helps for testbeds with high duration stretching (e.g. AWS). + Difference: No transaction scale, and we deal with floats. + Update loss counting to count unsent packets as lost. + Also count "unsent" transactions for other transaction types. + If nonzero, log the number of unsent packets/transactions. + Make STL and ASTF time overhead constant (called delay) configurable. + Subtract delay from approximated_duration, also for ASTF.

2021-03-22MLRsearch: Support other than just two ratiosVratko Polak1-17/+21
+ Change some method names and argument types: + Do not mention NDR and PDR, except as examples. + Return list of ReceiveRateInterval instead of NdrPdrResult. + The resulting intervals can be degenerate when hitting min/max rate. + Rename quantity name parts from "fraction" to "ratio". + Intervals are no longer tracked for each target ratio. + They are found dynamically from known results. + Add effective_loss_ratio field to avoid loss inversion effects. + Move some functions to separate files. + Bound search logic moved to MeasurementDatabase.py + ProgressState moved to its file. + WidthArithmetics.py holds small computation functions. + Use parameter expansion_coefficient instead of "doublings". + Do uneven bisect to save time when width is not power of two times goal. + Timeout now correctly tracked for the whole search, not just the current phase. + Make logging (debug) function pluggable. + Added debug log messages for initial phase. + Do not mark as subclass if contructor signature differs. + Avoid re-measure on scale-limited (ASTF) profiles. + Remove outdated comments. + Bump copyright years.

2020-10-29Support existing test types with ASTFVratko Polak1-331/+623
+ Add UDP_CPS, TCP_CPS, UDP_PPS and TCP_PPS suites. + Update existing cps traffic profiles. + Add missing traffic profiles. + UDP: + Single burst of 32 packets was confirmed as safe enough for TRex. + Maybe 64 could work, but not enough testing for that. + Multiple bursts have lead to reduced TRex performance, as overlaping bursts (from different client instances) tend to fill up the buffers. + TCP: + Data size set to 11111 bytes, completely arbitrarily. + Results look reasonable, so I have kept that. - MSS not set at all - No tested support for frame size other than 64B. - Frame size does not even factor into TCP profiles. + So other frame sizes are skipped in autogen. + Update tags in related suites. - HOSTS_{n} and SRC_USER_{n} should be unified. - Questionable clarification on difference between IP4BASE and SCALE. + Add NAT state resetters to tests that need them. + Resetter is called (if set) before each measurement. + If ramp-up is detected, resetter is not set. + Rename "mult" argument to "multiplier". + Abstracted from packets to transactions. + Transaction corresponds to profile. + TRex multiplier argument sets target rate in transactions per second. + The familiar STL traffic: + Bidirectional is considered to be 2 packets per transaction. + Unidirectional is considered to be 1 packet per transaction. + The newer ASTF traffic: + 4 subtypes, each has different number of packets per transaction. + For max rate computation: + Packets in the more numerous direction are considered. + Rely on TRex reported traffic duration for ASTF: + Use the server side value. - Client side value is higher by an overhead. - TRex is not sending traffic during that time. + Remove delays from traffic profiles. - Those delays would increase the reprted traffic time. + Support for scale lmited trials. + Only for ASTF profiles, each ASTF profile has limited scale. + Scale defined in suite variables. + For TRex to send all transactions provided duration value is ignored. + The appropriate value is computed in TrafficGenerator. + An ad-hoc time constant is added to match the TRex client side time overhead. + The profile driver receives the computed duration. + Measurement for PLRsearch add a sleep if the computed duration is smaller. + Alternative argument for search algos if scale is limited. + Both need higher timeout to accomodate big scales. + MLRsearch can afford fewer phases. + Added a parameter to optionally shorten the duration. + Use short duration for runtime stats trial and failure stats trial. + Use very large keepalive values in udp profiles to avoid ka packets. + No polling in ASTF profile driver. - Polling could eliminate the time overhead value. + But polling proved to introduce some loss, affecting the results. + Handle duration stretching in ASTF by stopping traffic. + The stop has several steps so that: + The traffic is really stopped entirely. + Late packets do not count (maybe as errors). + Stats are preserved to read for results (and cleared afterwards). + Several quantities added to ReceiveRateMeasurement: + Original target duration is preserved (algos need that). + Input estimate (tps) for early search iterations. + Output estimate (maybe pps) for MRR output. + Strict result (unsent counts as loss) for NDR. + Use L2 counters (opackets, ipackets) where possible. - TRex has trouble processing packets for the L7 ones at high loads. + Remove warmup from profile drivers and keywords. + Suites should call "Send ramp-up traffic" explicitly if needed. + Added parsing for few more counters. + Both to use in formulas or just for debug purposes. - Only 64B cases in autogen, framesize support to be added later. + Latency streams during search can be enabled via PERF_USE_LATENCY env var. + MLRsearch improvments: + Rename argument names to min_rate and max_rate. + Use relative receive rate in initial phase. + PLRsearch improvements: + Careful computation when output (pps) does not match input (tps). + Use geometric distribution (instead of Poisson). + Helps agains math errors. + This should improve estimate stability. - But in practice big losses still lead to significant jumps. + Traffic generator improvements: + send_traffic_on_tg now calls the full set_rate_provider_defaults. + _send_traffic_on_tg_internal for the logic without provider defaults. + As the internal function is re-used by measure() without affecting defaults. + Move _parse_traffic_results just before get_measurement_result. + As the latter uses fields set bu the former, it is now easier to read. + Multiple sources for approximate duration. + Tried from more precise to more available. + Includes logic for _pps tests (added in later change). + Move explicit type conversions to earlier occurences. + Profile driver output field uses semicolons to simplify parsing. + Performance Robot lib file split to several smaller ones. + performance_actions.robot: + Hosts Additional Statistics Action For * keywords. + performance_display.robot: + Hosts keyword for displaying and verifying results. + Change test message to use the correct unit (pps or cps). + performance_limits.robot renamed to performance_vars.robot + Added many keywords, mostly for accessing test variables. + Moved variables for Policer into a new keyword there. + Some keywords need sophisticated logic. - Other are basically Get Variable Value. + But in future more logic can be added, without editing callers. + Documentation for the new keywords acts as a documentation for test variables. + performance_utils.robot has the rest. + Eliminated arguments if the value is in test variable. + Small improvements to documentation. - Still not enough cleanup with respect to arguments and test variables. + Keywords are sorted alphabetically now in each one. + Suites: + Unified variables table: + No colons in comments. + ${n_hosts}, ${n_ports} and use them instead hardcoded numbers. + Add -cps to existing cps suite names. + Remove "trial data overwrite". + Compute max rate as in STL suites. + Each NAT suite has ip4base suite to compare results to. - Those act as indirect TRex calibration. - VPP does not lose packets in those. + Latency in ASTF suites is disabled hard. - As we do not support latency in ASTF profiles yet. + Unidirectional tests governed by suite variable, not an argument. + Write long argument lists vertically. + Prefer to use argument names. + In Python, also the last argument is followed by comma. + It makes renaming and reordering easier. + Similarly applies to prints with long lists of values. + A TODO to update api crc file comments.

2019-09-24Reconf tests: Fix async measurementsVratko Polak1-9/+38
TRex does not zero the server counters. It copies the values to use as reference, and subtracts them when asked for results. But the reference is stored in the client (not the server). And CSIT uses different scripts to start and stop async traffic, which means different clients. This patch introduces a workaround. Async start will return xstats objects to use as reference, and async stop will use the objects to compute the correct results. The xstats objects are stored in TrafficGenerator instance. Sync measurement does not export the counters, to shorten logs. Other improvements: + Make stop_traffic_on_tg return measurement results directly. + Rename --async to --async_start as "async" is reserved in Python 3.7 + Minor pylint, docstring and typo fixes.

Documented. + Clarified min framesize tags are for TG-DUT. + Added a TODO concerning overhead values. + Added 118B tag. + Robot performance keywords improvements. + Added missing return value documentation. + Frame size as required test variable, not an explicit argument. + MLRsearch keyword to store result (not into test message). - TODO: De-duplicate: main keyword to measure, minor to set test message. - But implementation uses the fact default arguments are different. + Keywords for starting and stopping background traffic. - No checks whether start-stop pair is complete. + Multiple minor indentation and logging improvements. - Missing / TODOs: - Support also vlan_per_chain=True? - Support dot1q without vxlan? - Support also deletion? - How to package config steps so -reconf can be generated from -ndrpdr?

2019-05-10PLRsearch: Use stat trackers to shorten IntegratorVratko Polak1-5/+6
+ Extract several tracker classes and use them in Integrator. + Apply next_rate workarounds to focus more on critical region. + Rewrite stretch function, as the previous implementation was wrong. + Rework logging: ++ Use injected trace() function in Integrator. ++ Inject function that skips trace logging on default initialization. ++ Use the same multiprocessing-safe passing, but separate queue. + Set duration to 120m in Robot, but keep at 30m in Python. + Apply minor changes to make computations more reproducible: ++ Attempt to log everything needed by reproducibility in one line. ++ Log samples used, and make it settable as upper limit. ++ Use repr output in TRex scripts, to avoid rounding when copypasting. +- Numpy seems to be sharing PRNG between processes. +-- An edit to disable one thread is needed for full reproducibility. +-- Such an edit is prepared, but will not be merged anytime soon.

2019-04-17Clean up traffic_profile vs osi_layerVratko Polak1-10/+10
The two types were not well distinguished before. Error introduced in: https://gerrit.fd.io/r/#/c/17811/84/resources/libraries/robot/performance/performance_setup.robot@255 Error hotfixed in: https://gerrit.fd.io/r/#/c/18847/4/resources/libraries/robot/shared/default.robot@109 + Rename some arguments and improve method docstrings. Newly introduced argument name osi_layer should be dissimilar enough. Change-Id: Ie0f6f97dc010fc6477f09c54574970f1d15462e2 Signed-off-by: Vratko Polak <vrpolak@cisco.com>
2019-04-08Upgrade autogen to NICs and search typesVratko Polak1-35/+37
+ All perf suites updated, as autogen change is backward incompatible. + Only x710 -ndrpdr suites remain in git repository. + Removed retry feature of run_tests. + Renamed topology_type and traffic_type to traffic_profile. + Renamed framesize to frame_size; nic_model to nic_name. + Reordered Variables table to start with nic_name and overhead. + Fixed wrong overhead value in some cbc-sha1 suites. + Fixed some suite tags. ++ Introduced tags to distinguish suites, such as IPSECINT. + Bound crypto hardware to NIC name. + Implemented NIC limit hiding. + Also search and teardown related arguments are now hidden. + Main measurement keywords updated to new arg handling. + Max rate related keywords moved to performance_limits.robot + Teardowns unified. + Generated tests are archived. ++ Generated directory is .gitignore-d. + Regenerator raises an exception on seeing non-compatible suite. ++ Relatively helpful message should be seen in exception. + Suite and template Documentation has generated parts. +- With short NIC names only. + Autogen checker also upgraded. + Tag expressions replaced with long files to ensure analogous tests.

2019-03-04Rename to Constants.pyVratko Polak1-1/+1
Motivation: Make the constants available also for Robot. Restraint: Robotframework user guide says: Because variable files are always imported using a file system path, creating them as classes has some restrictions: Python classes must have the same name as the module they are located.

2019-02-26De-duplicate unidirection supportVratko Polak1-125/+60
- Latency is now reported in both directions. -- For unidirection that means additional -1/-1/-1. + Changed function argument wrapping to save vertical space. + Changed trex command synthesys to save vertical space. + Fixed handling of command line arguments to avoid superfluous spaces. + More care distinguishing (0, 1) from (port_0, port_1). - Not renaming the original port arguments.
