Fragments - The Internet Protocol Journal - Volume 5, Number 2

The Institute of
Electrical and Electronics Engineers
(IEEE) has named Stephen D. Crocker, chief executive officer of Shinkuro, Inc. in Bethesda, Md., as recipient of the 2002
IEEE Internet Award
. The award recognizes Crocker for his leadership in the creation of key Internet protocols. It will be presented on 19 June, at INET 2002, in Arlington, Va.

In the formative days of the Internet and its predecessor, the ARPA-NET, Crocker led the development of crucial technologies, processes and organizations that continue to support the Internet today. At the University of California at Los Angeles, Crocker and his team developed protocols for the ARPANET such as the
Network Control Protocol
. NCP laid the groundwork for today's
Transmission Control Protocol
(TCP). Crocker also founded and led the
Network Working Group
(NWG), which has evolved to become the
Internet Engineering Task Force

In organizing the notes from the first few meetings of NWG, Crocker was anxious to expand the community and invite further discussion and responses, and thus named the series
Requests for Comments
. RFCs remain a mainstay of Internet protocol publishing today, and have played a big part in creating the environment of open and evolving standards of the Internet.

"The Internet Society is honored that INET 2002 was chosen as the venue to present this year's prestigious IEEE Internet Award," said Lynn St. Amour, president and CEO of the Internet Society (ISOC). "Dr. Stephen Crocker is highly regarded throughout the international Internet community and we're pleased that his contributions will be recognized at INET 2002 in front of his peers."

Crocker's many contributions to the Internet also include extensive work organizing the standards process of the IETF, where he has served as area director of security and on the Internet Architecture Board. Crocker previously worked for the University of Southern California Information Sciences Institute in Marina del Rey, the Aerospace Corporation in El Segundo, Calif., and at Trusted Information Systems, Inc., in Glenwood, Md. In 1994, he co-founded CyberCash of Reston, Va., and served as its senior vice president for development and chief technology officer. He also has started other ventures including Steve Crocker Associates in Bethesda, Md.; Executive DSL in Bethesda, Md.; and Longitude Systems in Chantilly, Va.

He has served on the Council of Visitors at the Marine Biological Laboratory, as part of the National Research Council Study of Information Systems Trustworthiness and currently chairs the ICANN Security and Stability Advisory Committee and the ISOC 2002 Jonathan B. Postel Service Award Committee. The author of numerous papers, Crocker also holds patents in relation to his security and electronic commerce work.

He received his bachelor's degree in mathematics and doctoral degree in computer science, both from UCLA, he and studied artificial intelligence at the Massachusetts Institute of Technology.

The IEEE is the world's largest technical professional society with more than 377,000 members in approximately 150 countries. Through its members, the IEEE is a leading authority on areas ranging from aerospace, computers and telecommunications to biomedicine, electric power and consumer electronics.

The Internet Society
is a non-profit, non-governmental, open membership organization whose worldwide individual and organization members make up a veritable "who's who" of the Internet industry. It provides leadership in technical and operational standards, policy issues, and education. ISOC is the organizational home of the International Engineering Task Force, the Internet Architecture Board, the Internet Engineering Steering Group, and the IETF—the standards setting and research arms of the Internet community.

Interim Approval for ENUM Provisioning

International Telecommunication Union
(ITU) and the
Internet Architecture Board
(IAB) recently announced interim approval for a single domain for ENUM, a technology that builds a bridge between the public switched telephone network and the Internet.

Voice on IP networks today operate by translating telephone numbers to IP addresses and placing an H.323 or SIP call to the device. The interchange format and translation record has not heretofore been standardized, limiting the possibility of deployment of multi-corporate and international Voice on IP services. Under the ENUM proposal, E.164 numbers can be represented as Internet Domain Names, providing a scalable and standard way to translate the numbers, and opening the way to such services. ITU has begun approving delegations for the purposes of trials. "The lack of an interoperable standard way to turn a telephone number into an IP Address has been one factor limiting the deployment of Voice on IP services internationally," said Leslie Daigle, Chair of the IAB.

If desk-mounted computers or servers are given telephone numbers as well as mnemonic names, this system further enables common telephone handsets to place Voice or Video on IP calls to such computers. This is a significant step towards integrating Internet-based services with the global telephone network, and the current agreements between IAB and ITU will allow trials to take place.

Patrik Fältström, member of the
Internet Engineering Steering Group
(IESG), said that "the integration of the desktop telephone and computer allows corporations to simplify their internal networks."

Roy Blane, Chair of ITU-T's Study Group 2, concurred, saying that "In the long term this protocol may facilitate many new internet services. In the short term, countries wishing to trial the system can begin work on developing it."

This interim approval is made possible due to cooperation between ITU, IAB and the IETF. As outlined in the ENUM specification document, RFC 2916, sub-domains from a single domain will be delegated after acceptance by the registries according to the existing assignment of country codes in the telephone address space. Information on how the ENUM registration requests will be processed can be found at:

The IETF is an international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet. The definition of the ENUM protocol, as proposed by the IETF can be found at
The IETF is an organized activity of the Internet Society.

The ITU is a global organization where the public and private sectors cooperate for the development of telecommunications and the harmonization of national telecommunications policies. Study Group 2 of the
ITU Telecommunication Standardization Sector
(ITU-T), where work on ENUM is being carried out, is the Lead Study Group on Service definition, Numbering, Routing and Global Mobility and is responsible for the operational aspects of service provision, networks and performance.

Committee on ICANN Evolution and Reform posts Recommendations

Following the publication in February of "President's Report: ICANN—The Case for Reform, " by Stuart Lynn, President and CEO of
The Internet Corporation for Assigned Names and Numbers
(ICANN), a committee of the board has been examining the details of the restructuring proposal, receiving input from the community at large, and publishing several documents with recommendations. You can find pointers to all of these documents in the "Announcements" section at

Errata List

This is the 17th issue of
The Internet Protocol Journal
. Inevitably, some minor, and a few major errors have made their way into print since our June 1998 issue. We are planning to publish a list of corrections on our Web site in the near future. Since the online material is a reflection of the printed version, we feel it would be inappropriate to simply "silently" correct the online editions, thereby rewriting history. Instead, a list of the errors along with the corrections will be presented.
