Introduction There are thousands of networks in the internet. There are tens of thousands of host machines. There are hundreds of thousands of users. It takes a great deal of effort to manage the resources and protocols which make the Internet possible. Sites may have people who get paid to manage their hardware and software. But the infrastructure of the Internet is managed by volunteers who spend considerable portions of their valued time to keep the people connected. Hundreds of people attend the three IETF meetings each year. They represent the government, the military, research institutions, educational institutions, and vendors from all over the world. Most of them are volunteers; people who attend the meetings to learn and to contribute what they know. There are a few very special people who deserve special notice. These are the people who sit on the IAB, IESG, and IRSG. Not only do they spend time at the meetings, but they spend additional time to organize them. They are the IETF's interface to other standards bodies and to the funding institutions. Without them, the IETF, indeed the whole Internet, would not be possible. 2. Acknowledgements In addition to the people who took the time to write their biographies so that I could compile them into this FYI RFC, I would like to give special thanks to Joyce K. Reynolds (whose biography is in here) for her help in creating the biography request message and for being such a good sounding board for me. 3. Request for Biographies In mid-February 1991, I sent the following message to the members of the IAB, IESG and IRSG. It is their responses to this message that I have compiled in this FYI RFC. The ARPANET is 20 years old. The next meeting of the IETF in St. Louis this coming March will be the 20th plenary. It is a good time to credit the people who help make the Internet possible. I am sending this request to the current members of the IAB, the Malkin [Page 2] RFC 1336 Who's Who May 1992 IRSG, and the IESG. At some future time, I would like to expand the number of people to be included. For now, however, I am limiting inclusion to members of the groups listed above. I would like to ask you to submit to me your biography. I intend to compile the bios submitted into an FYI RFC to be published before the next IETF meeting. In order to maintain some consistency, I would like to have the bios contain three paragraphs. The first paragraph should contain your bio, second should be your school affiliation & other interests, and the third should contain your opinion of how the Internet has grown. Of course, if there is anything else you would like to say, please feel free. The object is to let the very large user community know about the people who give them what they have. 4. Biographies The biographies are in alphabetical order. The contents have not been edited; only the formating has been changed. 4.1 Philip Almquist, IETF Internet Area Co-director Philip Almquist is an independent consultant based in San Francisco. He has worked on a variety of projects, but is perhaps best known as the network designer for INTEROP '88 and INTEROP '89. His career began at Carnegie-Mellon University in 1980, where he worked on compilers and operating systems. His initial introduction to networking was analyzing crash dumps from TOPS-20 systems running beta test versions of DECNET. He later became involved in early planning for CMU's transition from DECNet to TCP/IP and for network-based software support for the hundreds of PC's that CMU was then planning to acquire. Philip moved to Stanford University in 1983, where he played a key role in the evolution of Stanford's network from a small system built out of donated equipment by graduate students to today's production quality network which extends into virtually every corner of the University. As Stanford's first "hostmaster", he invented Stanford's distributed host registration system and led Stanford's deployment of the Domain Name System. He also did substantial work on the Stanford homebrew router software (now sold commercially by cisco Systems) and oversaw some early experiments in network management. Malkin [Page 3] RFC 1336 Who's Who May 1992 Also, while with Stanford, Philip was a primary contributor to BARRNet and its short-lived predecessor, the BayBridge Network. He brought up the first BARRNet link, and was heavily involved in the day-to-day operation of BARRNet for several years. In 1988, Philip gave up his responsibilities for the Stanford network in order to start his consulting business. He remained with BARRNet on a part-time basis until October 1991, devoting himself to BARRNet planning and to chairing its technical oversight committee. Philip has been an active participant in the IETF since about 1987, when he became a charter member of the IETF's Network Management Working Group. He is one of the authors of the Host Requirements specification, and served a brief term as chair of the Domain Name System Working Group. He is currently chairs of the Router Requirements Working Group. 4.2 Robert Braden, IAB Executive Director, IRSG Member Bob Braden joined the networking research group at ISI in 1986. Since then, he has been supported by NSF for research concerning NSFnet, and by DARPA for protocol research. Tasks have included designing the statspy program for collecting NSFnet statistics, editing the Host Requirements RFCs, and coordinating the DARPA Research Testbed network DARTnet. His research interests generally include end-to-end protocols, especially in the transport and network (Internet) layers. Braden came to ISI from UCLA, where he had worked 16 of the preceding 18 years for the campus computing center. There he had technical responsibility for attaching the first supercomputer (IBM 360/91) to the ARPAnet, beginning in 1970. Braden was active in the ARPAnet Network Working Group, contributing to the design of the FTP protocol in particular. In 1975, he began to receive direct DARPA funding for installing the 360/91 as a "tool-bearing host" in the National Software Works. In 1978, he became a member of the TCP Internet Working Group and began developing a TCP/IP implementation for the IBM system. As a result, UCLA's 360/91 was one of the ARPAnet host systems that replaced NCP by TCP/IP in the big changeover of January 1983. The UCLA package of ARPAnet host software, including Braden's TCP/IP code, was distributed to other OS/MVS sites and was later sold commercially. Braden spent 1981-1982 in the Computer Science Department of Malkin [Page 4] RFC 1336 Who's Who May 1992 University College London. At that time, he wrote the first Telnet/XXX relay system connecting the Internet with the UK academic X.25 network. In 1981, Braden was invited to join the ICCB, an organization that became the IAB, and has been an IAB member ever since. When IAB task forces were formed in 1986, he created and still chairs the End-to-End Task Force (now Research Group). Braden has been in the computer field for 40 years this year. Prior to UCLA, he worked at Stanford and at Carnegie Tech. He has taught programming and operating systems courses at Carnegie Tech, Stanford, and UCLA. He received a Bachelor of Engineering Physics from Cornell in 1957, and an MS in Physics from Stanford in 1962. ------------ Regardless of the ancient Chinese curse, living through interesting times is not always bad. For me, participation in the development of the ARPAnet and the Internet protocols has been very exciting. One important reason it worked, I believe, is that there were a lot of very bright people all working more or less in the same direction, led by some very wise people in the funding agency. The result was to create a community of network researchers who believed strongly that collaboration is more powerful than competition among researchers. I don't think any other model would have gotten us where we are today. This world view persists in the IAB, and is reflected in the informal structure of the IAB, IETF, and IRTF. Nevertheless, with growth and success (plus subtle policy shifts in Washington), the prevailing mode may be shifting towards competition, both commercial and academic. To develop protocols in a commercially competitive world, you need elaborate committee structures and rules. The action then shifts to the large companies, away from small companies and universities. In an academically competitive world, you don't develop any (useful) protocols; you get 6 different protocols for the same objective, each with its research paper (which is the "real" output). This results in efficient production of research papers, but it may not result in the kind of intellectual consensus necessary to create good and useful communication protocols. Being a member of the IAB is sometimes very frustrating. For some years now we have been painfully aware of the scaling Malkin [Page 5] RFC 1336 Who's Who May 1992 problems of the Internet, and since 1982 have lived through a series of mini-disasters as various limits have been exceeded. We have been saying that "getting big" is probably a more urgent (and perhaps more difficult) research problem than "getting fast", but it seems difficult to persuade people of the importance of launching the kind of research program we think is necessary to learn how to deal with Internet growth. It is very hard to figure out when the exponential growth is likely to stop, or when, if ever, the fundamental architectural model of the Internet will be so out of kilter with reality that it will cease be useful. Ask me again in ten years. 4.3 Hans-Werner Braun, IAB Member Hans-Werner Braun joined the San Diego Supercomputer Center as a Principal Scientist in January 1991. In his initial major responsibility as Co-Principal Investigator of, and Executive Committee member on the CASA gigabit network research project he is working on networking efforts beyond the problems of todays computer networking infrastructure. Between April 1983 and January 1991 he worked at the University of Michigan and focused on operational infrastructure for the Merit Computer Network and the University of Michigan's Information Technology Division. Starting out with the networking infrastructure within the State of Michigan he started to investigate into TCP/IP protocols and became very involved in the early stages of the NSFNET networking efforts. He was Principal Investigator on the NSFNET backbone project since the NSFNET award went to Merit in November 1987 and managed Merit's Internet Engineering group. Between April 1978 and April 1983 Hans- Werner Braun worked at the Regional Computing Center of the University of Cologne in West Germany on network engineering responsibilities for the regional and local network. In March 1978 Hans-Werner Braun graduated in West Germany and holds a Diploma in Engineering with a major in Information Processing. He is a member of
