John C. Klensin is a political scientist and computer science professional who is active in Internet-related issues. [2] [3]
His career includes 30 years as a principal research scientist at MIT, including a period as INFOODS Project Coordinator for the United Nations University, distinguished engineering fellow at MCI WorldCom, and Internet architecture vice president at AT&T; he is now an independent consultant. [2] [3]
Klensin was involved in The Cambridge Project, [4] a social science data management cooperation project taking place at MIT, Harvard and other universities from 1969 to 1977. As a part of this program, John Klensin led the development of the Consistent System [5] [6] [7] targeted for use by Social Scientists. The Consistent System ran on top of the Multics operating system.
His involvement with Internet protocols began in 1969, when he worked on the File Transfer Protocol. [8]
In 1992, Randy Bush and John Klensin created the Network Startup Resource Center, [9] helping dozens of countries to establish connections with FidoNet, UseNet, and when possible Internet.
Klensin is the author or co-editor of 60 RFCs, [10] and has served as IETF Applications Area director 1993-1995, [11] Internet Architecture Board member 1996-2002, and its chair 2000-2002. [12] He again served on the Board from 2009 to 2011. [13]
The RFCs written or edited by Klensin include SMTP (including RFC 4409 and RFC 5321), IDNA (including RFC 5890 and RFC 6055), Unicode (including RFC 5137 and RFC 5198), and other fields including CRAM-MD5 (RFC 2195) and IETF policies (RFC 3933). In March 2011 8BITMIME (RFC 6152) was published as Internet standard STD 71. In November 2011 Mail submission (RFC 6409) was published as STD 72.
His i18n work also included an April Fools' Day RFC in collaboration with Harald Alvestrand (RFC 5242) and MIME in collaboration with Ned Freed (RFC 4289 among others). As of 2011 [update] , he is a member of the RFC Independent Submissions Editorial Board. [14] He is working on several Internet drafts. [15]
Harald Tveit Alvestrand is a Norwegian computer scientist. He was chair of the Internet Engineering Task Force (IETF) from 2001 until 2005, succeeding Fred Baker. Within the IETF, Alvestrand was earlier the chair of the Areas for Applications from 1995 until 1997, and of Operations and Management in 1998.
In computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force (IETF). They allow interoperation of hardware and software from different sources which allows internets to function. As the Internet became global, Internet Standards became the lingua franca of worldwide communications.
In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by RFC 9051.
The Internet Engineering Task Force (IETF) is a standards organization for the Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors.
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.
The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 587 or 465 per RFC 8314. For retrieving messages, IMAP is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync.
Telnet is a client/server application protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. It is a protocol for bidirectional 8-bit communications. Its main goal was to connect terminal devices and terminal-oriented processes.
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 Internet Research Task Force (IRTF) is an organization, overseen by the Internet Architecture Board, that focuses on longer-term research issues related to the Internet. A parallel organization, the Internet Engineering Task Force (IETF), focuses on the shorter term issues of engineering and standards making.
Leslie B. Lamport is an American computer scientist and mathematician. Lamport is best known for his seminal work in distributed systems, and as the initial developer of the document preparation system LaTeX and the author of its first manual.
Paul V. Mockapetris is an American computer scientist and Internet pioneer, who invented the Internet Domain Name System (DNS).
Privacy-Enhanced Mail (PEM) is a de facto file format for storing and sending cryptographic keys, certificates, and other data, based on a set of 1993 IETF standards defining "privacy-enhanced mail." While the original standards were never broadly adopted and were supplanted by PGP and S/MIME, the textual encoding they defined became very popular. The PEM format was eventually formalized by the IETF in RFC 7468.
A message submission agent (MSA), or mail submission agent, is a computer program or software agent that receives electronic mail messages from a mail user agent (MUA) and cooperates with a mail transfer agent (MTA) for delivery of the mail. It uses ESMTP, a variant of the Simple Mail Transfer Protocol (SMTP), as specified in RFC 6409.
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.
Multipath TCP (MPTCP) is an ongoing effort of the Internet Engineering Task Force's (IETF) Multipath TCP working group, that aims at allowing a Transmission Control Protocol (TCP) connection to use multiple paths to maximize throughput and increase redundancy.
The Network Startup Resource Center (NSRC) is a nonprofit organization, formed in 1992 and based at the University of Oregon. The organization supports deployment of Internet research and education networks in academic institutions and non-governmental organizations throughout the Asia Pacific region, Africa, Latin America and the Caribbean, and the Middle East. NSRC receives major funding and in-kind donations from the National Science Foundation (NSF), Google and Google.org, Cisco, O'Reilly Media, Vint Cerf, the Richard M. Karp Foundation, IDRC, Internet Society (ISOC), and many other institutional and private donors.
Lixia Zhang is the Jonathan B. Postel Professor of Computer Science at the University of California, Los Angeles. Her expertise is in computer networks; she helped found the Internet Engineering Task Force, designed the Resource Reservation Protocol, coined the term "middlebox", and pioneered the development of named data networking.
Murray S. Kucherawy is a computer scientist, mostly known for his work on email standardization and open source software.
