Our Goal:

We are designing and implementing systems targeted at the wide-area Internet placing a central emphasis on working prototypes, empirical methods, and data-driven analysis. Our research activities span two broad areas.

On the one hand, we are designing systems for Internet Television using peer-to-peer technology, and addressing challenges in the safe, secure and robust deployment of such systems over the Internet. On the other hand, we are studying challenges in the management of enterprise networks. In particular, we are designing abstractions that capture operator intent, and building systems that can enable operators to better manage networks.

We colaborate with AT&T and Microsoft Research in various projects. Besides, we have been awarded grants from ATT, Cisco, and NSF.

Many of the challenges we address are motivated by real-world experience, require insights into operations of distributed systems at Internet scales, are great fun, and can change the world!
