This talk introduces Chimera, a novel fuzzing framework designed to uncover bugs and vulnerabilities within **P4 network infrastructure**. Presented by Jiwon Kim from Purdue University, with collaboration from Georgetown University, the research addresses critical shortcomings in existing testing methodologies for programmable networks. Traditional network testing tools often focus on either the data plane or the control plane in isolation, failing to account for the complex interdependencies that lead to multi-plane bugs. Chimera fundamentally shifts this paradigm by providing **multi-plane inputs** simultaneously and employing a sophisticated **P4 concrete execution (P4CE)** engine as a reliable bug oracle.
