Systems & Network Bench Notes
Kernel packet paths, transport protocols, and measurement telemetry

About the Telemetry Bench

This notebook records empirical measurements taken across our Linux network testing nodes and transpacific test circuits. The focus is on packet dynamics: socket queue behavior, transport pacing, eBPF tracing, and the performance boundaries of standard kernel paths versus kernel-bypass architectures.

Instrumentation & Testing Rig

Measurement nodes run modern Debian/Linux kernels (6.6+ PREEMPT_RT and vanilla kernels) with Intel and Mellanox 10/25GbE NICs utilizing hardware timestamping (PTP/IEEE 1588). Traffic generation is executed via DPDK, MoonGen, and custom AF_XDP pipelines to ensure probe traffic does not perturb the measured characteristics.

There are no tracking scripts, analytics, or comment boxes. The pages are static documents compiled from engineering logs.
