Mr. David H. Crocker

A Senior Advisor of the Messaging Anti-Abuse Working Group, active in the IETF, and self-employed working under the company name Brandenburg InternetWorking. He currently designs network-based applications businesses and system architectures. He has forty years of work experience in the Internet industry, including early work with DARPA and designing the basis for today's email system. He is well-known for his work on RFC 822, which was the first standard to describe the syntax of a domain name. He received his B.A. in Psychology from UCLA in (1975), his M.A. in Communication from Annenberg School, USC (1977) and pursued Doctoral work in Computer Science from University of Delaware (1978-1982). He began his networking career in the 1970's, when he worked for four years at UCLA with ARPANET. He was the Area Director for the IETF from 1989-1996. He participated in the effort to standardize facsimile, and electronic data exchange over the Internet. He chaired the Silicon Valley?Public Access Link in the early 1990s. He has also contributed to work on Internet commerce, domain name service, emergency services, and TCP/IP enhancements. He was one of Jon Postel's appointees to the IAHC. He has also taught several classes on Internet, TCP/IP and Open Systems Networking. From 1989 to 1991, he worked as the Manager of Network Systems Laboratory, Digital Equipment Corporation, prior to which he was the Vice President of Engineering at The Wollongong Group, Inc. He has also held the position of Development Manager at Ungermann-Bass, Inc. and has worked as the Director of System Development at MCI Digital Information Services Corp, where he worked with Vint Cerf to build a national email service for the company. Prior to this, he worked as the Co-Principal Investigator, Electrical Engineering at University of Delaware. He is responsible in part for the facilitation and growth of email. He developed MS, based on the design of MSG, which was the first modern email sender program. MS was designed for UNIX operating system. The idea was initiated by Steve Walker, who was then the Program Manager at DARPA. He designed the functional specifications and Steve Tepper and Bill Crosby did the programming, reporting to the Rand department head, Bob Anderson. In 1977, he along with John Vittal, Kenneth Pogran, and Austin Henderson worked on a DARPA initiative that was meant to collect various email data formats into a single, coherent specification. The result of their work was RFC 733. In 1982, He revised RFC 733 and prepared RFC 822, which was the first standard to describe the syntax of domain names. In 1978, he was once again with Dave Farber at the University of Delaware, where they developed the first versions of what would become the Multi-purpose Memo Distribution Facility (MMDF). This project was for the U.S. Army Materiel Command, and served as the foundation of CSNet. He has developed two national email services and designed two others. He has worked as an Advisor at Goodmail Systems, the Co-Founder of Portola Software, an Engineer at Silicon Graphics, and Director at Digital Equipment Corporation. Much of his recent work revolves around email anti-abuse, working towards a trust overlay on the Internet. He is currently a member of the IETF's administrative and legal oversight bodies (IAOC/Trust). He is also a member of Association of Computing Machinery, Institute of Electrical & Electronic Engineers, and ISOC. He actively participates in meetings in the Internet industry and has chaired and presented at several conferences, including: N+I Interop; Electronic Messaging Association; APRICOT '06, '05, '04, '99; RIPE, Edinburgh; EMail World; Unix Expo and FTC email authentication conference in 2004. He is the author of book chapters, magazine articles, presentations and specifications on open systems networking, standards, electronic mail and electronic commerce. A complete list of his presentations and publications can be read at http://www.bbiw.net/musings.html. In 2004, he received the IEEE Internet Award.
