Douglas Comer

Douglas Earl Comer is a professor of computer science at Purdue University, where he teaches courses on operating systems and computer networks. He has written numerous research papers and textbooks, and currently heads several networking research projects. He has been involved in TCP/IP and internetworking since the late 1970s, and is an internationally recognized authority. He designed and implemented X25NET and Cypress networks, and the Xinu operating system. He is director of the Internetworking Research Group at Purdue, editor of Software - Practice and Experience, and a former member of the Internet Architecture Board. Comer completed the original version of Xinu (and wrote correspondent book The Xinu Approach) in 1979. Since then, Xinu has been expanded and ported to a wide variety of platforms, including: IBM PC, Macintosh, Digital Equipment Corporation VAX and DECstation 3100, Sun Microsystems Sun-2, Sun-3 and SPARCstations, and Intel Pentium. It has been used as the basis for many research projects. Furthermore, Xinu has been used as an embedded system in products by companies such as Motorola, Mitsubishi, Hewlett-Packard, and Lexmark.

Education and career
Comer holds a BS in Mathematics and Physics from Houghton College earned in 1971 and a PhD in Computer Science from Pennsylvania State University earned in 1976. He is a Distinguished Professor of Computer Science and professor of electrical and computer engineering at Purdue University in the US. Beginning in the late 1970s he started his continuing research into TCP/IP, which has earned him international fame in the field of Computer Science and computer networking.

Achievements
Douglas Comer headed a number of research projects associated with the creation of the Internet, and is the author of a number of books on Operating Systems, the Internet and TCP/IP networking, and computer architecture.

Comer is also the developer of the Xinu operating system.

Comer is well known for his series of ground breaking textbooks on computer networks, the Internet, computer operating systems, and computer architecture. His books have been translated into sixteen languages, and are widely used in both industry and academia. Comer's three-volume series Internetworking With TCP/IP is often cited as an authoritative reference for the Internet protocols.

For twenty years, Comer served as editor-in-chief of the research journal Software—Practice And Experience, published by John Wiley & Sons. Comer is a Fellow of the ACM and the recipient of numerous teaching awards.
