Leveraging Large Language Models for Automated Reproduction of Networking Research Results

Code reproduction is a cornerstone of scientific validity, yet it remains a formidable challenge in computer networking research due to the scarcity of open-source implementations and the complexity of heterogeneous system architectures. While Large Language Models have demonstrated potential in code generation, existing code generation frameworks often fail to address the long-context constraints and intricate logical dependencies required to reproduce network systems from academic papers. To facilitate result reproduction, we introduce \emph{RepLLM}, an end-to-end multi-agent framework designed to automate the transformation of network research into executable code. RepLLM features a novel collaborative architecture comprising four specialized agents – Content Parsing, Architecture Design, Code Generation, and Audit & Repair – coordinated through an explicit $\mathit{\text{Shared}}\mathit{\text{Memory}}$ mechanism to ensure global context consistency. With the enhancement of Chain-of-Thought LLM reasoning and a sandbox-isolated static-dynamic debugging methodology, our framework effectively resolves semantic discrepancies and runtime errors. Extensive evaluations on representative papers from SIGCOMM and NSDI demonstrate that RepLLM significantly outperforms state-of-the-art baselines in generating compile-ready and logically correct systems. Results further demonstrate that RepLLM facilitates the reproduction of 80% of the original benchmarks with only four hours of human intervention.
