Research

A programmable network and the five lines of work that study it. Hover over a line to highlight it in the network.

Programmable networks

Programmable control and data planes (SDN and P4) to manage, monitor and protect the network in software, including traffic engineering with reinforcement learning.
Virtualization and resource allocation

Virtual network embedding, service function chain composition and placement (NFV), and cloud and edge orchestration, formulated as optimization problems.
Network cybersecurity

Detection and mitigation of DDoS attacks and intrusions with machine and self-supervised learning, open datasets and in-network detection in the data plane.
Networks for critical infrastructure

Communication networks for IEC 61850 digital substations, smart grids and microgrids: reliability, quality of service and security.
Engineering education

Remote laboratories for networking education and adaptive learning strategies supported by learning analytics.
