Welcome to the Systems and Networking (SYN) Lab

The Systems and Networking (SYN) Lab at Purdue University led by Prof. Ramana Rao Kompella conducts research related to broad topics in the area of computer networks and systems. Since our lab was founded in 2007, we have been focusing on challenging research problems related to measurement, monitoring, fault diagnosis, and security in the Internet. We are also beginning to look at performance optimizations and performance monitoring in virtualized, cloud-based, and data-center environments.
