We present Minesweeper, a tool to verify that a network satisfies a wide range of intended
properties such as reachability or isolation among nodes, waypointing, black holes …

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 …

Declarative Networking is a programming methodology that enables developers to concisely
specify network protocols and services, which are directly compiled to a dataflow framework …

Network operators often need to adapt the configuration of a network in order to comply with
changing routing policies. Evolving existing configurations, however, is a complex task as …

Today's distributed network control planes are highly sophisticated, with multiple interacting
protocols operating at layers 2 and 3. The complexity makes network configurations highly …

This paper presents Aquila, the first practically usable verification system for Alibaba's
production-scale programmable data planes. Aquila addresses four challenges in building a …

The control plane of most computer networks runs distributed routing protocols that
determine if and how traffic is forwarded. Errors in the configuration of network control …

When debugging a distributed system, it is sometimes necessary to explain the absence of
an event-for instance, why a certain route is not available, or why a certain packet did not …

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 …

Introduction The NEBULA Future Internet Architecture (FIA) project is focused on a future
network that enables the vision of cloud computing [8, 12] to be realized. With computation …
