Internet Measurements

We collect and analyze data, like network topologies and traffic traces, to better understand various facets of the Internet ecosystem, like the behaviour of malware, the exhaustion of IP addresses, and the interconnections between Internet Service Providers (ISPs).

Software Defined Networks

We study how to exploit the rapidly emerging SDN paradigm to counter chronic problems of the Internet, including unpredictable network availability, lack of Quality of Service guarantees, and vulnerability to established and new types of Denial of Service (DoS) attacks.

Network Monitoring Systems

We design and build sophisticated network monitoring systems for efficiently processing, storing, and querying big network data, like traffic traces collected at line rates of 10Gbps and above.
