Systems and Networking

The systems and networking group at UCSD engages in a wide range of experimental and theoretical research. Our current projects span fault-tolerant networks and systems, high-speed router design, storage system design, network measurement and traffic analysis, peer-to-peer system design, network security, mobile code architectures, high-performance cluster computing, and wireless networking. Our group consists of 8 core faculty, again as many affiliated faculty (in a broad range of areas including security, machine learning and programming languages) and over 40 graduate students and research staff, and our work is well-supported through generous funding from government and industrial sources.
