We present the design and implementation of p4v, a practical tool for verifying data planes
described using the P4 programming language. The design of p4v is based on classic …

By moving network functionality from dedicated hardware to software running on end-hosts,
Network Functions Virtualization (NFV) pledges the benefits of cloud computing to packet …

In-network Access Control List (ACL) is an important technique in ensuring network-wide
connectivity and security. As cloud-scale WANs today constantly evolve in size and …

We present Vera, a tool that verifies P4 programs using symbolic execution. Vera
automatically uncovers a number of common bugs including parsing/deparsing errors …

This paper describes an approach to designing, implementing, and formally verifying the
functional correctness of an OS kernel, named Hyperkernel, with a high degree of proof …

We describe our experiences using formal methods and automated theorem proving for
network operation at scale. The experiences are based on develo** and applying the …

We present PacketMill, a system for optimizing software packet processing, which (i)
introduces a new model to efficiently manage packet metadata and (ii) employs code …

Modern programmers routinely use third-party code, and infrastructure operators deploy
software they did not write. This would not be possible without semantic interfaces …

We present the design and implementation of Vigor, a software stack and toolchain for
building and running software network middleboxes that are guaranteed to be correct, while …

Centralized data plane verification (DPV) faces significant scalability issues in large
networks (ie, the verifier being a performance bottleneck and single point of failure and …
