This extended abstract proposes a novel use of partial evaluation to enable troubleshooting of modern networks. Our key insight is that partial evaluation provides a systematic approach to pre-process the complexity in modern networks, such as compressing large network configurations or compiling away layers of network semantics that hinder analysis. Furthermore, we introduce the concept of a dual partial evaluation process that, based on troubleshooting feedback, seeks to uncover the relevant or faulty parts in the original network.
