PacAna™ is an inline Ethernet test platform designed to reproduce, isolate, and analyze intermittent network failures that cannot be captured or recreated using conventional tools.

By combining packet manipulation, fault injection, and precise timing control, PacAna enables engineers to transform rare, non-deterministic issues into repeatable and debuggable events.

  • Real-time packet inspection and modification

  • Deterministic fault injection engine

  • Script-driven operation

System Architecture

  • Multiple Ethernet ports (A0, A1, B0, B1)

  • Command/control interface (serial or equivalent)

  • Scriptable control for automation environments

  • Suitable for lab and system-level testing

  • Supports automated test frameworks

  • Enables repeatable validation workflow

Interface & Integration

Example Use Case

A system experiences a packet timing fault once every several hours.

Using PacAna:

  • The fault condition is recreated by injecting controlled delay

  • The issue is reproduced in seconds

  • Root cause is identified rapidly
