Computer networks are a key enabling technology. The Internet has not only changed the global economy — it also affects our private lives in many ways. The Internet has become a critical infrastructure, often considered alongside food, water, and energy supply. To provide robust and resilient network services that can scale to support large numbers of users, it is necessary to design the network and services as distributed systems that can tolerate failures, dynamically shift work loads, and stay responsive even in the face of attacks on the infrastructure. The group of Prof. Jürgen Schönwälder researches computer networks and distributed systems.
