A Programmable Framework for Validating Data Planes.

Due to the emerging trend of programmable network hardware, developers have begun to explore ways to accelerate various applications and services. As a result, there is a pressing need for new tools and techniques for debugging network devices. This paper presents NetDebug, a fully programmable hardware-software framework for validating and real-time debugging of programmable data planes. We describe validation use cases, compare our design to alternative solutions, and present a preliminary evaluation using a prototype implementation.
