Why don't we verify networks like other complex systems?

In recent weeks, I have been working with my colleagues on an update to our SDN book, including a fresh look at the future of SDN. We believe network verification will be an important...

Modular Verification in Compositional Network Architecture

In our first article on Compositional Network Architecture, we emphasized its value as a descriptive model. This article considers its uses as a prescriptive model of network architec...

Compositional Network Architecture

Compositional Network Architecture is a new descriptive model of networking, possibly the first since the “classic” Internet architecture of the late 1980s. You all know the classic a...

Network verification 2.0

The first generation of network verification research, or Network Verification 1.0, has been tremendously successful. It has produced a wide range of methods that enable strong guaran...

The Verification-Synthesis Spectrum

Toward Polynomial-Time Verification of Networks with Infinite State Spaces: An Automata-Theoretic Approach

With the increasing scale of communication networks, failures (e.g. link failures) are becoming the norm rather than theexception. Given the critical role such networks play for ourdi...

Talk to a network operator today!

Recently, we have seen significant advances in tools that bring formal methods to networking. These tools verify if a given network satisfies important properties, automatically repai...

Models for Distributed Routing Protocols

Part 1: SIMPLE Models and Simulation

It’s the Equivalence Classes, Stupid

James Carville coined the phrase “It’s the economy, stupid” to say that what mattered in an election year was the economy. Formal methods search through vast state spaces in reasonabl...

You can't verify what you can't specify

Back when I was studying for my master degree, Prof. Axel van Lamsweerde wasteaching us formal logic. Axel is world-famous for his works on requirementsengineering, that is, the proce...

Toward modular network verification

Almost all of the techniques for network verification to date must analyze the entire network’s state and/or configuration data monolithically. In contrast, methodologies for verific...

Capturing the state of research on network verification

Verification and synthesis are old problems in computer science. Verification seeks to answer the question: “can any input to a program result in that program producing an incorrect o...

Welcome to netverify.fun

Network verification and synthesis has emerged as an exciting research area at the intersection of networking, programming languages, and formal methods. Work in this area is motivate...

Harnessing Formal Methods Beyond Routing Layer

Network verification is a mature field with an industrial presence developed to ensure networks and services are safe from configuration-related outages. However, researchers in this ...
