Özalp Babaoğlu

BSD Unix

During his PhD work at UC Berkeley, Babaoğlu was one of the architects of “BSD Unix” which was a major factor in the rapid growth of the Internet with its built-in TCP/IP stack and has influenced numerous other modern operating systems including FreeBSD, NetBSD, and OpenBSD, SunOS, Mac OS/X and iOS. His virtual memory system, implemented with Bill Joy, the co-founder of Sun Microsystems, became a core part of the kernel of Unix/32V, the first 32-bit version of Unix, written for the DEC VAX minicomputer, a hardware lacking page reference bits. The Berkeley version of UNIX became the standard in education and research, garnering development support from DARPA, and was notable for introducing virtual memory and inter-networking using TCP/IP. BSD Unix was widely distributed in source form so that others could learn from it and improve it; this style of software distribution has led to the open source movement, of which BSD Unix is now recognized to be one of the earliest examples.

Research Areas

Babaoğlu is the author of more than 100 peer-reviewed papers in a wide range of research topics, including:

• Operating Systems
• Performance Evaluation and Modeling
• Distributed Computing
• Byzantine Agreement
• Parallel Computing on Networks of Workstations
• Group Communication Systems
• Peer-to-Peer Systems. Babaoğlu has contributed to peer-to-peer computing through paradigms, algorithms, frameworks (Anthill) and a widely used open source simulation software package (PeerSim)
• Autonomic Computing and Self-Management
• Gossip-Based Aggregation
• Overlay Networks and Topology Management
• Decentralized Shape Formation
• Biology and Nature-Inspired Computing. As part of work on the EU-funded BISON Project, Babaoğlu and colleagues have developed a library of “design patterns” for distributed computing that draw inspiration from biological or natural processes.
• Game-Theoretic Techniques in Peer-to-Peer Systems
• Cloud Computing
• High-Performance Computing
