Blackbox Performance Analysis of LLM-based Network Control

However, auditing these systems is challenging due to the inherent opacity of LLMs. LENS is the first step towards black-box performance analysis of LLM-enabled network control systems.

Key points

  • LLMs are becoming an indispensable part of network control systems due to their impressive reasoning.
  • Before such LLM-enabled systems can be deployed, it is imperative to develop tools that can audit their performance on previously unseen inputs.
  • It uses novel methods to extend deep reinforcement learning to guide the search for performance gaps and inputs that make LLMs struggle.
  • LENS finds large gaps for LLM-based traffic engineering and GPU allocation systems, and even matches existing white-box analyzers designed for hand-crafted TE heuristics.
