The Center for Networked Systems (CNS), established in 2004, forms a hub for some of the leading research in networked systems and security. CNS brings together researchers in the UCSD community with those in industry to develop key technologies and frameworks for networked systems and foster a lively intellectual community that works to accelerate the advancement of innovation in the field. Our areas of expertise and activity involve modeling network traffic and topology, network security (including botnets, spam, and the underground economy), data center architecture, energy efficiency, thermal and energy management in computational infrastructure and wireless devices, “cloud” computing; data center networking, wireless system performance, and diagnosis, and database organization for unstructured (“XML”) data.
