CSNET Receives 2009 Postel Service Award

The Internet Society (ISOC) has awarded the Jonathan B. Postel Service Award for 2009 to CSNET, the Computer Science Network, a research networking effort that during the early 1980s provided the critical bridge from the original research undertaken through the ARPANET to the modern Internet.

The award recognizes the pioneering work of the four principal investigators that conceived and later led the building of CSNET—Peter J. Denning, David Farber, Anthony C. Hearn and Lawrence Landweber—and the U.S. National Science Foundation program officer and visionary responsible for encouraging and funding CSNET—Kent Curtis.

Stephen Wolff, a past recipient of the Postel Award, said, "CSNET was a critical link in the transition from the research-oriented ARPANET to today's global Internet. CSNET also helped lead the way by sharing technologies, fostering connections, and nurturing the worldwide community that provided a foundation for the global expansion of the Internet."

ISOC presented the award, including a US$20,000 honorarium and a crystal engraved globe, during the 75th meeting of the Internet Engineering Task Force (IETF) in Stockholm, Sweden. The awardees have requested that the ISOC present the honorarium to non-profit organizations they believe support the spirit of the award.

Lynn St. Amour, President and CEO of the ISOC, said "In many ways, CSNET helped set the stage for the Internet that today reaches more than 1 billion people. CSNET's community-driven, self-sustaining governance structure was an early example of the model that helps ensure that even as today's Internet grows and evolves, it remains an open platform for innovation around the world."

CSNET began in 1981 with a five-year grant from the U.S. National Science Foundation (NSF). Five years later, CSNET connected more than 165 academic, government and industrial computer research groups comprised of more than 50,000 researchers, educators and students across the United States and around the world. It had concluded a seminal resource sharing agreement with the ARPANET and was self-governing and self-supporting. Open to all computer researchers, it demonstrated that researchers valued the kind of informal collaboration it made possible. CSNET's success was critical to the decision by NSF in 1986 to adopt the Internet technology for NSFNET, the network backbone to connect its supercomputing centers and their research communities. CSNET provided software, policies, and experienced alumni to the NSFNET teams. NSFNET became the first backbone of the modern Internet.

The CSNET architecture supported the Internet standards, SMTP and TCP/IP, and a variety of connection protocols including telephone dialup, X.25, and ARPANET. This architecture, along with strong technical support, enabled participants of differing means and skill levels to all join the community. CSNET pioneered the model of university, industry, government partnerships that were key to the pre-commercial Internet.

The CSNET proposal was assembled by a lengthy community consensus process that began in 1979. The four principal investigators, who led this effort and served as the project's management committee, were:

Peter Denning was head of the computer science department at Purdue University. His team included professor Douglas Comer, who was responsible for the software that ran TCP/IP over the GTE Telenet X.25 commercial packet network.

David Farber was a professor of electrical engineering at University of Delaware. His team included then graduate student David Crocker, who was responsible for Phonenet, dial-in telephone connections to relay servers for e-mail exchange.

Anthony Hearn was head of the information sciences department at RAND. His team included Michael O'Brien, who was responsible for the relays connecting CSNET and ARPANET.

Lawrence Landweber was a professor of computer science at the University of Wisconsin. His team included professor Marvin Solomon and Michael Litzkow who were responsible for the name server, a precursor of modern Directory Services.

At the NSF, the late Kent Curtis helped conceive the entire effort and, with assistance from Bill Kearn, saw it through its formative years. He was recognized for his pivotal role by the Computing Research Association's first distinguished service award in 1988.

The Jonathan B. Postel Service Award was established by the Internet Society to honor individuals or organizations that, like Jon Postel, have made outstanding contributions in service to the data communications community. The award is focused on sustained and substantial technical contributions, service to the community, and leadership. With respect to leadership, the nominating committee places particular emphasis on candidates who have supported and enabled others in addition to their own specific actions. Previous recipients of the Postel Award include Jon himself (posthumously and accepted by his mother), Scott Bradner, Daniel Karrenberg, Stephen Wolff, Peter Kirstein, Phill Gross, Jun Murai, Bob Braden and Joyce K. Reynolds (jointly), Nii Quaynor, and La Fundación Escuela Latinoamericana de Redes (EsLaRed). The award consists of an engraved crystal globe and a US$20,000 honorarium.

ISOC is dedicated to ensuring the open development, evolution, and use of the Internet for the benefit of people throughout the world. More information is available at: http://www.isoc.org

NRO Declaration on RPKI

The Number Resource Organization (NRO) recently declared: "Over several years, a set of mechanisms has been under development for digital certification of Internet number resources, through a so-called Resource Public Key Infrastructure, or "RPKI." Like other PKIs, the RPKI requires one or more root authorities, to act as so-called trust anchors for one or more certification hierarchies. [1]

The RPKI architecture has been designed to allow a number of trust anchor configurations involving: either a single trust anchor located at the root of a single certification hierarchy; a set of independent trust anchors to be located at the roots of several independent hierarchies; or a hybrid of these. The alternative models may have advantages and disadvantages in various dimensions including: operational efficiency; alignment with resource allocation hierarchies; centralisation vs distribution of functions; recognised global or regional authority; and, operational capacity of the respective host organisations.

The Regional Internet Registries (RIRs) believe that the optimal eventual RPKI configuration involves a single authoritative trust anchor. That configuration may not be achievable in the short-term and the details and timelines for its implementation will depend among other things on discussions within the RIR' communities and dialogues with others including the Internet Architecture Board (IAB) and the Internet Engineering Task Force (IETF).

In the meantime, the RIRs have agreed to undertake pragmatic implementations of RPKI services based on interim trust anchor models, such as, self-signed trust anchors. All such implementations will comply with the overall RPKI architecture. The implementations will also have the ability to evolve into a single trust anchor model and to provide robust and fully operational (and inter-operational) services for those who wish to use them. The objective is for all RIRs to be ready to start issuing certificates by no later than January 1, 2011.

The RIRs will continue working with and receiving feedback from their respective communities and industry partners to ensure effective ongoing evolution of the RPKI system.

ARIN Hosts 4-byte ASN Wiki

The American Registry for Internet Numbers (ARIN) has created a wiki to focus on issues related to 4-byte Autonomous System Numbers (ASNs) [2]. This wiki provides a central repository for ongoing discussion and information exchange associated with 4-byte ASN topics and issues. The wiki can be found at: www.get4byteasn.info

Ongoing Internet growth is rapidly depleting the existing pool of 2-byte ASNs (65,536 numbers in total). As a result, the IETF has approved the expansion of AS Numbers from 2-bytes to 4-bytes, to include over 4 billion ASNs. Following a globally coordinated policy, ARIN and the other RIRs began assigning 4-byte ASNs by request in January 2007 and by default in January 2009. However, some routers do not support the use of these 4-byte ASNs.

ARIN has set up this wiki to help educate the community about 4-byte ASN operational issues, to help vendors understand how to provide 4-byte ASN support in their products and to help network operators find those products. A wide range of community stakeholders will be able to share and benefit from information contributed to the wiki. ARIN looks forward to participation from everyone, including users, ISPs, and vendors, with interest in this topic.
