Stephen D. Crocker (born October 15, 1944) is an Internet pioneer. In 1969, he created the ARPA "Networking Working Group" and the Request for Comments series. He served as chair of the board of the Internet Corporation for Assigned Names and Numbers (ICANN) from 2011 through 2017. [1] [2] [3]
Steve Crocker attended Van Nuys High School, as did Vint Cerf and Jon Postel. Crocker received his bachelor's degree (1968) and PhD (1977) from the University of California, Los Angeles. [4]
He has worked in the Internet community since its inception. He was instrumental in creating the ARPA "Network Working Group" and the instigator of the Request for Comment (RFC) series, [5] authoring the first RFC [6] and many more. [7] As a UCLA graduate student in the 1960s, he was part of the team that developed the protocols for the ARPANET which were the foundation for today's Internet. [8]
While at UCLA Crocker taught an extension course on computer programming (for the IBM 7094 mainframe computer). The class was intended to teach digital processing and assembly language programming to high school teachers, so that they could offer such courses in their high schools. A number of high school students were also admitted to the course, to ensure that they would be able to understand this new discipline. Crocker was also active in the newly formed UCLA Computer Club.
Crocker has been a program manager at Defense Advanced Research Projects Agency (DARPA), a senior researcher at USC's Information Sciences Institute, founder and director of the Computer Science Laboratory at The Aerospace Corporation and a vice president at Trusted Information Systems. In 1994, Crocker was one of the founders and chief technology officer of CyberCash, Inc. [9] [10] In 1998, he founded and ran Executive DSL, a DSL-based ISP. In 1999 he cofounded and was CEO of Longitude Systems. He is currently CEO of Shinkuro, [11] a research and development company.
The Networking Working Group RFC's provided the context in which the IETF was created in 1986. He has been an IETF security area director, a member of the Internet Architecture Board, chair of the ICANN Security and Stability Advisory Committee, board member and chairman of ICANN, a board member of the Internet Society and numerous other Internet-related volunteer positions.
For his work on the Internet, Crocker was awarded the 2002 IEEE Internet Award. [12] In 2012, Crocker was inducted into the Internet Hall of Fame by the Internet Society. [13]
The history of the Internet has its origin in information theory and the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA.
Jonathan Bruce Postel was an American computer scientist who made many significant contributions to the development of the Internet, particularly with respect to standards. He is known principally for being the Editor of the Request for Comment (RFC) document series, for Simple Mail Transfer Protocol (SMTP), and for administering the Internet Assigned Numbers Authority (IANA) until his death. During his lifetime he was referred to as the "god of the Internet" for his comprehensive influence; Postel himself noted that this "compliment" came with a barb, the suggestion that he should be replaced by a "professional," and responded with typical self-effacing matter-of-factness: "Of course, there isn’t any 'God of the Internet.' The Internet works because a lot of people cooperate to do things together."
A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF). An RFC is authored by individuals or groups of engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. It is submitted either for peer review or to convey new concepts, information, or, occasionally, engineering humor.
Vinton Gray Cerf is an American Internet pioneer and is recognized as one of "the fathers of the Internet", sharing this title with TCP/IP co-developer Bob Kahn.
A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connectionless communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not be guaranteed by the network.
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols and Internet numbers.
InterNIC, known as the Network Information Center (NIC) until 1993, was the organization primarily responsible for Domain Name System (DNS) domain name allocations and X.500 directory services. From its inception in 1972 until October 1, 1991, it was run by the Stanford Research Institute, now known as SRI International, and led by Jake Feinler. From October 1991 until September 18, 1998, it was run by Network Solutions. Thereafter, the responsibility was assumed by the Internet Corporation for Assigned Names and Numbers (ICANN).
The Internet Architecture Board (IAB) is "a committee of the Internet Engineering Task Force (IETF) and an advisory body of the Internet Society (ISOC). Its responsibilities include architectural oversight of IETF activities, Internet Standards Process oversight and appeal, and the appointment of the Request for Comments (RFC) Editor. The IAB is also responsible for the management of the IETF protocol parameter registries."
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.
The Network Control Protocol (NCP) was a communication protocol for a computer network in the 1970s and early 1980s. It provided the transport layer of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet.
The domain name arpa is a top-level domain (TLD) in the Domain Name System (DNS) of the Internet. It is used predominantly for the management of technical network infrastructure. Prominent among such functions are the subdomains in-addr.arpa and ip6.arpa, which provide namespaces for reverse DNS lookup of IPv4 and IPv6 addresses, respectively.
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. In later years the IMPs were made from the non-ruggedized Honeywell 316 which could handle two-thirds of the communication traffic at approximately one-half the cost. An IMP requires the connection to a host computer via a special bit-serial interface, defined in BBN Report 1822. The IMP software and the ARPA network communications protocol running on the IMPs was discussed in RFC 1, the first of a series of standardization documents published by what later became the Internet Engineering Task Force (IETF).
Robert Braden was an American computer scientist who played a role in the development of the Internet. His research interests included end-to-end network protocols, especially in the transport and network layers.
WHOIS is a query and response protocol that is used for querying databases that store an Internet resource's registered users or assignees. These resources include domain names, IP address blocks and autonomous systems, but it is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format. The current iteration of the WHOIS protocol was drafted by the Internet Society, and is documented in RFC 3912.
Einar A. Stefferud (Stef) was a computer researcher and entrepreneur, who made many significant contributions to the development of the Internet, particularly in the areas of IETF RFCs and standards, secure online payment systems, DNS, and secure email. Stefferud was one of the original designers of the MIME protocol for sending multimedia Internet electronic mail.
Mark James Handley is Professor of Networked Systems in the Department of Computer Science of University College London since 2003, where he leads the Networks Research Group.
Elizabeth Jocelyn "Jake" Feinler is an American information scientist. From 1972 until 1989 she was director of the Network Information Systems Center at the Stanford Research Institute. Her group operated the Network Information Center (NIC) for the ARPANET as it evolved into the Defense Data Network (DDN) and the Internet.
A long-running debate in computer science known as the Protocol Wars occurred from the 1970s to the 1990s when engineers, organizations and nations became polarized over the issue of which communication protocol would result in the best and most robust computer networks. This culminated in the Internet–OSI Standards War in the 1980s and early 1990s, which was ultimately "won" by the Internet protocol suite (TCP/IP) by the mid-1990s and has since resulted in most other protocols disappearing.
