How can network-wide control architectures and programmable data planes be designed to enforce network-level objectives across enterprise, data-center, and Internet-scale networks? The group pursues software-defined networking and network virtualization projects such as SDX, RCP/4D, and SoftCell to explore scalable control and virtualization for operators. Researchers develop data-plane mechanisms and compact on-switch data structures for telemetry and traffic engineering, including programmable-switch sketches and Δ-sketches, to enable in-network measurement. Researchers build and evaluate prototypes on testbeds and campus/backbone deployments and document results in conference publications and technical reports. Researchers study interdomain routing, traffic engineering, and measurement to evaluate routing, policy mechanisms, and network-wide control strategies.
