CHAOS

Contested, Hostile, Austere Operating System

An in-line, transparent Layer-2 WAN-emulation appliance for defensible test & evaluation. Drop it on any link with no DUT reconfiguration, author or replay a network-conditions scenario, and walk away with a sealed, hardware-timestamped test artifact that holds up under technical scrutiny.

Know before
you field it.

Nobody buys CHAOS for the chaos. They buy knowing how their system behaves when the network turns hostile. Patch it in between two sites, give the link the network your system will meet, and leave with a sealed answer. This is that bench, in your browser.

Put CHAOS in the path.

Site A is a drone ground station; Site B is the ops centre that depends on its feed. Drag Site A's cable into PORT1, then the other into the other port. CHAOS is a transparent bridge, so nothing on either side gets reconfigured.

Nothing is reaching Site B yet. Patch both sites into CHAOS to bring the link up.

Illustrative, computed in your browser; no network traffic. The same impairment is applied to both ports. File time: Mathis TCP model. Voice: simplified ITU-T G.107 E-model, G.711. Video freezes: an illustrative estimate. Pass thresholds are examples; on a real bench you set your own.

01

Drop in-line

Place the appliance on any link. Transparent at Layer 2 — no DUT reconfiguration required.

02

Author / replay

Define a network-conditions scenario in TOML, or replay a captured one. Per-direction, time-varying.

03

Walk away

Leave with a sealed, hardware-timestamped test artifact that holds up under technical scrutiny.

Defensible by design.
Prototype available.

CHAOS runs on the ETHRX-ONE hardware platform — a TPM-anchored, hardware-timestamped appliance built for test & evaluation that has to survive scrutiny. The CHAOS-2 prototype reference unit is a candidate SKU available for evaluation today.
