Network Topology Benchmark Dataset

📊 Dataset Overview

This dataset is designed to test large language models' ability to process network topologies, including two main tasks: building from scratch and modifying existing topologies.

Directory	File Count	Description
origin/	90	Original network topologies (empty + original)
nl/	792	Natural language descriptions (396 Chinese + 396 English)
netjson/	396	Ground Truth NetJSON files

Total: 1278 files
