Northwestern Networks Group Research
We do research in computer networking. Lately, we have focused on the following research questions:
-
How can we build robust protocols in presence of Denial of Service (DoS) attacks?
DoS attacks are presenting an increasing threat to the global networking infrastructure. Our research efforts are focused on discovering and thwarting new types of attacks. Indeed, without a vision to anticipate, understand, and intercept novel DoS attacks, we can be placed in the unfortunate position of witnessing the collapse of the Internet.
-
How can we build efficient protocols in heterogeneous network environments?
The Internet keeps bringing new stresses, from novel applications, skewed flow-size distributions, to diverse environments with vastly different characteristics. As a result, network protocols more than often operate in regions they were never designed for. Our research interests are in addressing heterogeneity-induced problems for congestion control, routing, and medium-access protocols.

How can we use network measurements to better understand the Internet and to build more efficient protocols?
Network measurements are essential for proper functioning of the Internet. Our research interests are in using measurements to (i) reveal how the Internet is build and how it operates, but also to (ii) more explicitly utilize measurements as an operational tool and an inevitable building block in the networking protocol design.
