Note

Add handshakes-per-second benchmark support across orchestrator and CI

  • Splits run_benchmark.py into throughput and handshake subcommands; throughput is now download-only and handshake takes concurrency and duration_seconds
  • Adds HandshakeResult data model and abstract run_handshake_test to QuicImplementation; reshapes ThroughputResult to bytes, duration_seconds, bits_per_second and removes upload fields
  • Implements run_handshake_test for both msquic.py and quic_go.py, with test-aware output parsers that return the correct result type
  • Converts benchmark.yml to a reusable workflow_call and adds manual handshake.yml and throughput.yml entrypoints; updates report and summary scripts to render scenario-specific tables
  • Behavioral Change: ThroughputResult drops upload_bytes/upload bit-rate fields and the abstract throughput method no longer accepts an upload-byte parameter; any out-of-tree callers using the old shape must update

Summary by CodeRabbit

  • New Features

    • Added dedicated throughput and handshake benchmark workflows with configurable locations, machine types, duration, concurrency, and download size.
    • Added handshake benchmarking support for both supported implementations.
    • Benchmark reports now identify the test type and display scenario-specific results.
  • Changes

    • Throughput benchmarks now measure downloads only; upload measurements and options were removed.
    • Integration runs now separately cover throughput and handshake scenarios.
  • Tests

    • Added coverage for download and handshake result parsing.

🟠 High workflows/orchestrator.yml:81

The quic-go handshake step always exits during argument parsing instead of producing a measurement because quic-go/perf has no handshake subcommand or --duration-seconds/--concurrency options. Remove this step until the built binary supports a handshake benchmark.

🟠 High orchestrator/msquic.py:54

Every MsQuic throughput test fails to produce a measurement because -pctput:1 is not SecNetPerf's throughput-output switch, so the required Result: Download ... line is absent and _parse_result raises ValueError. Use the documented -ptput:1 option instead.

Benchmark scenario support

Layer / File(s) Summary
Scenario result contracts
orchestrator/quic_implementation.py
ThroughputResult now stores download bytes, duration, and rate. HandshakeResult stores handshake rate and optional counts. The interface adds handshake execution and removes the throughput upload-size parameter.
Scenario execution and parsing
orchestrator/run_benchmark.py, orchestrator/quic_go.py, orchestrator/msquic.py, orchestrator/test_run_benchmark.py
The CLI supports throughput and handshake subcommands. Quic-go and MsQuic parse scenario-specific output and execute download-only or handshake commands. Tests cover both result types and scenario parameters.
Workflow scenario orchestration
.github/workflows/*.yml
Reusable workflow inputs now include scenario-specific parameters. New manual throughput and handshake workflows delegate to the reusable workflow. The orchestrator runs explicit throughput and handshake jobs, and artifacts and publication messages include the scenario.
Scenario report rendering
.github/scripts/benchmark_report.py, .github/scripts/benchmark_summary.py
Reports store the selected test. Summaries render separate download and handshake tables with their corresponding measurements.

Merge Risk: 🔵 Low · up to 368e1

The handshake benchmark path lacks an end-to-end mocked test, so regressions in dispatch or emitted results could reach workflows undetected. Add coverage before merge or accept this bounded risk.

Exercise the handshake CLI path.

test_handshakes only tests parser output. It does not call main() with handshake. A regression in handshake dispatch, parameters, or JSON serialization would pass the current tests. Add one mocked handshake invocation through main() and assert the emitted record, including test, parameters, and measurements.
